1 - Adding Content

So you’ve got a new Hugo website with Docsy, now it’s time to add some content! This page tells you how to use the theme to add and structure your site content.

Content root directory

You add content for your site under the content root directory of your Hugo site project - either content/ or a language-specific root like content/en/. The main exception here is static files that you don’t want built into your site: you can find out more about where you add these below in Adding static content. The files in your content root directory are typically grouped in subdirectories corresponding to your site’s sections and templates, which we’ll look at in Content sections and templates.

You can find out more about Hugo directory structure in Directory Structure Explained.

Content sections and templates

Hugo builds your site pages using the content files you provide plus any templates provided by your site’s theme. These templates (or “layouts” in Hugo terminology) include things like your page’s headers, footers, navigation, and links to stylesheets: essentially, everything except your page’s specific content. The templates in turn can be made up of partials: little reusable snippets of HTML for page elements like headers, search boxes, and more.

Because most technical documentation sites have different sections for different types of content, the Docsy theme comes with the following templates for top-level site sections that you might need:

• docs is for pages in your site’s Documentation section.
• blog is for pages in your site’s Blog.
• community is for your site’s Community page.

It also provides a default “landing page” type of template with the site header and footer, but no left nav, that you can use for any other section. In this site and our example site it’s used for the site home page and the About page.

Each top-level section in your site corresponds to a directory in your site content root. Hugo automatically applies the appropriate template for that section, depending on which folder the content is in. For example, this page is in the docs subdirectory of the site’s content root directory content/en/, so Hugo automatically applies the docs template. You can override this by explicitly specifying a template or content type for a particular page.

If you’ve copied the example site, you already have appropriately named top-level section directories for using Docsy’s templates, each with an index page ( _index.md or index.html) page for users to land on. These top-level sections also appear in the example site’s top-level menu.

Custom sections

If you’ve copied the example site and don’t want to use one of the provided content sections, just delete the appropriate content subdirectory. Similarly, if you want to add a top-level section, just add a new subdirectory, though you’ll need to specify the layout or content type explicitly in the frontmatter of each page if you want to use any existing Docsy template other than the default one. For example, if you create a new directory content/en/amazing and want one or more pages in that custom section to use Docsy’s docs template, you add type: docs to the frontmatter of each page:

• Front matter:
• toml
• yaml
• json

+++
title = "My amazing new section"
weight = 1
type = "docs"
description = '''
A special section with a docs layout.
'''
+++

---
title: "My amazing new section"
weight: 1
type: docs
description: >
  A special section with a docs layout.  
---

{
  "title": "My amazing new section",
  "weight": 1,
  "type": "docs",
  "description": "A special section with a docs layout.\n"
}

Alternatively, create your own page template for your new section in your project’s layouts directory based on one of the existing templates.

You can find out much more about how Hugo page layouts work in Hugo Templates. The rest of this page tells you about how to add content and use each of Docsy’s templates.

Alternative site structure

As noted above, by default your site has a home page (using the _default layout), a docs section under /开发文档/, a blog section under /更新日志/ and a community section under /技术交流/. The type of each section (which determines the layout it uses) matches its directory name.

In some cases, you may want to have a different directory structure, but still make use of Docsy’s layouts. A common example is for a “docs site”, where most of the pages (including the home page) use the docs layout, or perhaps you’d rather have a /news/ directory treated with the blog layout.

Since Hugo 0.76, this has become practical without copying layouts to your site, or having to specify type: blog on every single page by making use of target specific cascading front matter.

For example, for the /news/ section, you can specify the following front matter in the index page which will change the type of the section and everything below it to “blog”:

• Front matter:
• toml
• yaml
• json

+++
title = "Latest News"
linkTitle = "News"

[menu.main]
weight = 30

[[cascade]]
type = "blog"
+++

---
title: "Latest News"
linkTitle: "News"
menu:
  main:
    weight: 30

cascade:
  - type: "blog"
---

{
  "title": "Latest News",
  "linkTitle": "News",
  "menu": {
    "main": {
      "weight": 30
    }
  },
  "cascade": [
    {
      "type": "blog"
    }
  ]
}

If you want to create a “docs” site, specifying something like the following in the top level _index.md will set all top level sections to be treated as “docs”, except for “news”:

• Front matter:
• toml
• yaml
• json

+++
title = "My Wonderful Site"

[[cascade]]
type = "blog"
toc_root = true

  [cascade._target]
  path = "/news/**"

[[cascade]]
type = "docs"

  [cascade._target]
  path = "/**"
+++

---
title: "My Wonderful Site"

cascade:
  - type: "blog"
    toc_root: true
    _target:
    path: "/news/**"
  - type: "docs"
    _target:
    path: "/**"
---

{
  "title": "My Wonderful Site",
  "cascade": [
    {
      "type": "blog",
      "toc_root": true,
      "_target": {
        "path": "/news/**"
      }
    },
    {
      "type": "docs",
      "_target": {
        "path": "/**"
      }
    }
  ]
}

Note the addition of toc_root here. Setting that to true for a section causes it to be treated as a separate part of the site, with its own left hand navigation menu.

An example docs-based site that uses this technique can be found at the mostly docs repo.

Page frontmatter

Each page file in a Hugo site has metadata frontmatter that tells Hugo about the page. You specify page frontmatter in TOML, YAML, or JSON (our example site and this site use YAML). Use the frontmatter to specify the page title, description, creation date, link title, template, menu weighting, and even any resources such as images used by the page. You can see a complete list of possible page frontmatter in Front Matter.

For example, here’s the frontmatter for this page:

• Front matter:
• toml
• yaml
• json

+++
title = "Adding Content"
linkTitle = "Adding Content"
weight = 1
description = '''
Add different types of content to your Docsy site.
'''
+++

---
title: "Adding Content"
linkTitle: "Adding Content"
weight: 1
description: >
  Add different types of content to your Docsy site.  
---

{
  "title": "Adding Content",
  "linkTitle": "Adding Content",
  "weight": 1,
  "description": "Add different types of content to your Docsy site.\n"
}

The minimum frontmatter you need to provide is a title: everything else is up to you! However, if you leave out the page weight, your navigation may get a little disorganized. You may also want to include description since Docsy uses that to generate the meta description tag used by search engines. See Search Engine Optimization (SEO) meta tags for details.

Page contents and markup

By default you create pages in a Docsy site as simple Markdown or HTML files with page frontmatter, as described above. As of version 0.100, Goldmark is the only Markdown parser supported by Hugo.

[markup]
  [markup.goldmark]
    [markup.goldmark.renderer]
      unsafe = true

markup:
  goldmark:
    renderer:
      unsafe: true

{
  "markup": {
    "goldmark": {
      "renderer": {
        "unsafe": true
      }
    }
  }
}

In addition to your marked-up text, you can also use Hugo and Docsy’s shortcodes: reusable chunks of HTML that you can use to quickly build your pages. Find out more about shortcodes in Docsy Shortcodes.

Working with links

Hugo lets you specify links using normal Markdown syntax, though remember that you need to specify links relative to your site’s root URL, and that relative URLs are left unchanged by Hugo in your site’s generated HTML.

Alternatively you can use Hugo’s helper ref and relref shortcodes for creating internal links that resolve to the correct URL. However, be aware this means your links will not appear as links at all if a user views your page outside your generated site, for example using the rendered Markdown feature in GitHub’s web UI.

You can find (or add!) tips and gotchas for working with Hugo links in Hugo Tips.

Content style

We don’t mandate any particular style for your page contents. However, if you’d like some guidance on how to write and format clear, concise technical documentation, we recommend the Google Developer Documentation Style Guide, particularly the Style Guide Highlights.

Page bundles

You can create site pages as standalone files in their section or subsection directory, or as folders where the content is in the folder’s index page. Creating a folder for your page lets you bundle images and other resources together with the content.

You can see examples of both approaches in this and our example site. For example, the source for this page is just a standalone file /content/en/开发文档/adding-content.md. However the source for Docsy Shortcodes in this site lives in /content/en/开发文档/adding-content/shortcodes/index.md, with the image resource used by the page in the same /shortcodes/ directory. In Hugo terminology, this is called a leaf bundle because it’s a folder containing all the data for a single site page without any child pages (and uses index.md without an underscore).

You can find out much more about managing resources with Hugo bundles in Page Bundles.

Adding docs and blog posts

The template you’ll probably use most often is the docs template (as used in this page) or the very similar blog template. Both these templates include:

• a left nav
• GitHub links (populated from your site config) for readers to edit the page or create issues
• a page menu

as well as the common header and footer used by all your site’s pages. Which template is applied depends on whether you’ve added the content to the blog or docs content directory. You can find out more about how the nav and page menu are created in Navigation and Search.

Organizing your documentation

While Docsy’s top-level sections let you create site sections for different types of content, you may also want to organize your docs content within your docs section. For example, this site’s docs section directory has multiple subdirectories for Getting Started, Content and Customization, and so on. Each subdirectory has an _index.md (it could also be an _index.html), which acts as a section index page and tells Hugo that the relevant directory is a subsection of your docs.

Docsy’s docs layout gives you a left nav pane with an autogenerated nested menu based on your docs file structure. Each standalone page or subsection _index.md or _index.html page in the 开发文档/ directory gets a top level menu item, using the link name and weight metadata from the page or index.

To add docs to a subsection, just add your page files to the relevant subdirectory. Any pages that you add to a subsection in addition to the subsection index page will appear in a submenu (look to the left to see one in action!), again ordered by page weight. Find out more about adding Docsy’s navigation metadata in Navigation and Search

If you’ve copied the example site, you’ll already have some suggested subdirectories in your docs directory, with guidance for what types of content to put in them and some example Markdown pages. You can find out more about organizing your content with Docsy in Organizing Your Content.

Docs section landing pages

By default a docs section landing page (the _index.md or _index.html in the section directory) uses a layout that adds a formatted list of links to the pages in the section, with their frontmatter descriptions. The Content and Customization landing page in this site is a good example.

To display a simple bulleted list of links to the section’s pages instead, specify simple_list: true in the landing page’s frontmatter:

• Front matter:
• toml
• yaml
• json

+++
title = "Simple List Page"
simple_list = true
weight = 20
+++

---
title: "Simple List Page"
simple_list: true
weight: 20
---

{
  "title": "Simple List Page",
  "simple_list": true,
  "weight": 20
}

To display no links at all, specify no_list: true in the landing page’s frontmatter:

• Front matter:
• toml
• yaml
• json

+++
title = "No List Page"
no_list = true
weight = 20
+++

---
title: "No List Page"
no_list: true
weight: 20
---

{
  "title": "No List Page",
  "no_list": true,
  "weight": 20
}

Organizing your blog posts

Docsy’s blog layout also gives you a left nav menu (like the docs layout), and a list-type index page for your blog that’s applied to /更新日志/_index.md and automatically displays snippets of all your recent posts in reverse chronological order.

To create different blog categories to organize your posts, create subfolders in 更新日志/. For instance, in our example site we have news and releases. Each category needs to have its own _index.md or _index.html landing page file specifying the category title for it to appear properly in the left nav and top-level blog landing page. Here’s the index page for releases:

• Front matter:
• toml
• yaml
• json

+++
title = "New Releases"
linkTitle = "Releases"
weight = 20
+++

---
title: "New Releases"
linkTitle: "Releases"
weight: 20
---

{
  "title": "New Releases",
  "linkTitle": "Releases",
  "weight": 20
}

To add author and date information to blog posts, add them to the page frontmatter:

• Front matter:
• toml
• yaml
• json

+++
date = 2018-10-06T00:00:00.000Z
title = "Easy documentation with Docsy"
linkTitle = "Announcing Docsy"
description = "The Docsy Hugo theme lets project maintainers and contributors focus on content, not on reinventing a website infrastructure from scratch"
author = "Riona MacNamara"

[[resources]]
src = "**.{png,jpg}"
title = "Image #:counter"

  [resources.params]
  byline = "Photo: Riona MacNamara / CC-BY-CA"
+++

---

title: "Easy documentation with Docsy"
linkTitle: "Announcing Docsy"
description: "The Docsy Hugo theme lets project maintainers and contributors focus on content, not on reinventing a website infrastructure from scratch"
author: Riona MacNamara
resources:
  - src: "**.{png,jpg}"
    title: "Image #:counter"
    params:
    byline: "Photo: Riona MacNamara / CC-BY-CA"
---

{
  "date": "2018-10-06T00:00:00.000Z",
  "title": "Easy documentation with Docsy",
  "linkTitle": "Announcing Docsy",
  "description": "The Docsy Hugo theme lets project maintainers and contributors focus on content, not on reinventing a website infrastructure from scratch",
  "author": "Riona MacNamara",
  "resources": [
    {
      "src": "**.{png,jpg}",
      "title": "Image #:counter",
      "params": {
        "byline": "Photo: Riona MacNamara / CC-BY-CA"
      }
    }
  ]
}

If you’ve copied the example site and you don’t want a blog section, or want to link to an external blog instead, just delete the blog subdirectory.

Working with top-level landing pages.

Docsy’s default page template has no left nav and is useful for creating a home page for your site or other “landing” type pages.

Customizing the example site pages

If you’ve copied the example site, you already have a simple site landing page in content/en/_index.html. This is made up of Docsy’s provided Hugo shortcode page blocks.

To customize the large landing image, which is in a cover block, replace the content/en/featured-background.jpg file in your project with your own image (it can be called whatever you like as long as it has background in the file name). You can remove or add as many blocks as you like, as well as adding your own custom content.

The example site also has an About page in content/en/项目简介/_index.html using the same Docsy template. Again, this is made up of page blocks, including another background image in content/en/项目简介/featured-background.jpg. As with the site landing page, you can replace the image, remove or add blocks, or just add your own content.

Building your own landing pages

If you’ve just used the theme, you can still use all Docsy’s provided page blocks (or any other content you want) to build your own landing pages in the same file locations.

Adding a community page

The community landing page template has boilerplate content that’s automatically filled in with the project name and community links specified in hugo.toml/hugo.yaml/hugo.json, providing your users with quick links to resources that help them get involved in your project. The same links are also added by default to your site footer.

• Configuration file:
• hugo.toml
• hugo.yaml
• hugo.json

[params.links]

          "desc": "Discuss development issues around the project"
        }
      ]
    }
  }
}

If you’re creating your own site and want to add a page using this template, add a /技术交流/_index.md file in your content root directory. If you’ve copied the example site and don’t want a community page, just delete the /content/en/技术交流/ directory in your project repo.

Adding static content

You may want to serve some non-Hugo-built content along with your site: for example, if you have generated reference docs using Doxygen, Javadoc, or other doc generation tools.

To add static content to be served “as-is”, just add the content as a folder and/or files in your site’s static directory. When your site is deployed, content in this directory is served at the site root path. So, for example, if you have added content at /static/reference/cpp/, users can access that content at http://{server-url}/reference/cpp/ and you can link to pages in this directory from other pages at /reference/cpp/{file name}.

You can also use this directory for other files used by your project, including image files. You can find out more about serving static files, including configuring multiple directories for static content, in Static Files.

RSS feeds

Hugo will, by default, create an RSS feed for the home page and any section. For the main RSS feed you can control which sections to include by setting a site param in your hugo.toml/hugo.yaml/hugo.json. This is the default configuration:

• Configuration file:
• hugo.toml
• hugo.yaml
• hugo.json

[params]
rss_sections = ["blog"]

params:
  rss_sections: [blog]

{
  "params": {
    "rss_sections": [
      "blog"
      ]
  }
}

To disable all RSS feeds, add the following to your hugo.toml/hugo.yaml/hugo.json:

• Configuration file:
• hugo.toml
• hugo.yaml
• hugo.json

[params]
disableKinds = ["RSS"]

params:
  disableKinds: [RSS]

{
  "params": {
    "disableKinds": [
      "RSS"
      ]
  }
}

[outputs]
section = [ "HTML", "RSS", "print" ]

outputs:
  section:
    - HTML
    - RSS
    - print

{
  "outputs": {
    "section": [
      "HTML",
      "RSS",
      "print"
    ]
  }
}

Sitemap

Hugo creates a sitemap.xml file for your generated site by default: for example, here’s the sitemap for this site.

You can configure the frequency with which your sitemap is updated, your sitemap filename, and the default page priority in your hugo.toml/hugo.yaml/hugo.json:

• Configuration file:
• hugo.toml
• hugo.yaml
• hugo.json

[sitemap]
  changefreq = "monthly"
  filename = "sitemap.xml"
  priority = 0.5

sitemap:
  changefreq: monthly
  filename: sitemap.xml
  priority: 0.5

{
  "sitemap": {
    "changefreq": "monthly",
    "filename": "sitemap.xml",
    "priority": 0.5
  }
}

To override any of these values for a given page, specify it in page frontmatter:

• Front matter:
• toml
• yaml
• json

+++
title = "Adding Content"
linkTitle = "Adding Content"
weight = 1
description = '''
Add different types of content to your Docsy site.
'''
[sitemap]
priority = 1
+++

---
title: "Adding Content"
linkTitle: "Adding Content"
weight: 1
description: >
  Add different types of content to your Docsy site.  
sitemap:
  priority: 1.0
---

{
  "title": "Adding Content",
  "linkTitle": "Adding Content",
  "weight": 1,
  "description": "Add different types of content to your Docsy site.\n",
  "sitemap": {
    "priority": 1
  }
}

To learn more about configuring sitemaps, see Sitemap Template.

2 - Look and Feel

By default, a site using Docsy has the theme’s default fonts, colors, and general look and feel. However, if you want your own color scheme (and you probably will!) you can very easily override the theme defaults with your own project-specific values - Hugo will look in your project files first when looking for information to build your site. And because [Docsy uses Bootstrap 5] and SCSS for styling, you can override just single values (such as project colors and fonts) in its special SCSS project variables file, or do more serious customization by creating your own styles.

Docsy also provides options for styling your code blocks, using either Chroma or Prism for highlighting.

Project style files

To customize your project’s look and feel, create your own version of the following Docsy placeholder files (note the _project*.scss suffixes) and place them inside your project’s assets/scss/ folder:

• _variables_project.scss and
  _variables_project_after_bs.scss :

  Use these files to add project-specific definitions of theme variables as well as any additional Bootstrap variables you want to set or override. For details, including an explanation of which file to use, see Site colors.

  For a list of Docsy’s theme variables and their default values, see _variables.scss. For information about other Bootstrap 5 variables, see Variable defaults and Bootstrap’s _variables.scss file.

• _styles_project.scss is where you can add your own custom SCSS styles, including overriding any of the styles in Docsy’s theme SCSS files.

Colors and color themes

Site colors

To customize your site’s colors, add SCSS variable overrides to assets/scss/_variables_project.scss. For example, you can set the primary and secondary site colors as follows:

$primary: #390040;
$secondary: #a23b72;

Docsy has Bootstrap features such as gradient backgrounds ($enable-gradients) and shadows ($enable-shadows) enabled by default. These can also be toggled in your project variables file by setting the variables to false.

To add colors to or modify Bootstrap’s color maps, use assets/scss/_variables_project_after_bs.scss. For example:

$custom-colors: (
  'my-favorite-color': purple,
  'my-other-color': pink,
);

$theme-colors: map-merge($theme-colors, $custom-colors);

Light/dark color themes

Docsy 0.10.0 supports light and dark mode color themes. To allow your website users to choose light/dark modes, enable the Docsy light/dark menu or create your own custom theme selector.

If your site uses Chroma for code highlighting, there are extra steps required so that code-block styles are compatible with light/dark mode:

• Ensure that markup.highlight.noClasses is false in your project config. For details about this option, see Generate syntax highlighter CSS.
• Add @import 'td/code-dark' to your project’s _styles_project.scss file.

For details, see Chroma for code highlighting.

Fonts

The theme uses Open Sans as its primary font. To disable Google Fonts and use a system font, set this SCSS variable in assets/scss/_variables_project.scss:

$td-enable-google-fonts: false;

To configure another Google Font:

$google_font_name: 'Open Sans';
$google_font_family: 'Open+Sans:300,300i,400,400i,700,700i';

Note that if you decide to go with a font with different weights (in the built-in configuration this is 300 (light), 400 (medium) and 700 (bold)), you also need to adjust the weight related variables, i.e. variables starting with $font-weight-.

CSS utilities

For documentation of available CSS utility classes, see the Bootstrap documentation. This theme adds very little on its own in this area. However, we have added some color state CSS classes that can be useful in a dynamic context:

• .-bg-<color>
• .-text-<color>

You can use these classes, for example, to style your text in an appropriate color when you don’t know if the primary color is dark or light, to ensure proper color contrast. They are also useful when you receive the color code as a shortcode parameter.

The value of <color> can be any of the color names, primary, white, dark, warning, light, success, 300, blue, orange etc.

When you use .-bg-<color>, the text colors will be adjusted to get proper contrast:

<div class="-bg-primary p-3 display-6">Background: Primary</div>
<div class="-bg-200 p-3 display-6">Background: Gray 200</div>

To only set the text color use .-text-<color>:

<div class="-text-blue pt-3 display-6">Text: Blue</div>

Code highlighting with Chroma

As of Hugo 0.60+, you can choose from a range of code block highlight and color styles using Chroma. These styles are applied to your fenced code blocks. For details about code highlighting in Hugo using Chroma, see Syntax Highlighting.

Chroma style configuration

Hugo’s default Chroma style is monokai. To use another style, such as tango, add the following to your project configuration:

• Configuration file:
• hugo.toml
• hugo.yaml
• hugo.json

[markup]
  [markup.highlight]
      style = "tango"

markup:
  highlight:
    style: tango

{
  "markup": {
    "highlight": {
      "style": "tango"
    }
  }
}

For the complete list of available styles, see Chroma Style Gallery.

Light/dark code styles

Docsy’s default Chroma styles for light/dark mode are:

• tango for light mode
• onedark for dark mode

If you would like to use other styles, save the Hugo generated Chroma styles to the appropriate file:

• assets/scss/td/chroma/_light.scss
• assets/scss/td/chroma/_dark.scss

Code blocks without a specified language

By default, highlighting is not applied to code blocks without a specified language. If you would like code highlighting to apply to all code blocks, even without a language, set markup.highlight.guessSyntax to true in your project’s configuration file.

Copy to clipboard

If you are using a Docsy 0.6.0 or later, code blocks show a “Copy to clipboard” button in the top right-hand corner. To disable this functionality, set disable_click2copy_chroma to true in your configuration file:

Code highlighting with Prism

Optionally, you can enable Prism syntax highlighting in your hugo.toml/hugo.yaml/hugo.json:

• Configuration file:
• hugo.toml
• hugo.yaml
• hugo.json

[params]
prism_syntax_highlighting = true

params:
  prism_syntax_highlighting: true

{
  "params": {
    "prism_syntax_highlighting": true
  }
}

When this option is enabled your site uses Prism instead of Chroma for code block highlighting.

Prism is a popular open source syntax highlighter which supports over 200 languages and various plugins.

Docsy includes JavaScript and CSS files for a basic Prism configuration, which supports:

• Code blocks styled with the Prism Default theme
• Copy to clipboard buttons on code blocks
• Syntax highlighting for a number of common languages, as specified in the following Prism download link, Customize your download.

Code blocks with no language

By default, Prism code highlighting styles are not applied to code blocks without a specified language, instead you get Docsy’s default style of grey with black text. To apply Prism styling to code blocks with no language or a language not supported by Prism, specify none as the language after your triple backticks.

Extending Prism for additional languages or plugins

If the included Prism configuration is not sufficient for your requirements, and you want to use additional languages or plugins you can replace the included files with your own.

1. Download your own Prism JS and CSS files from https://prismjs.com/download.html
2. Replace the included Prism JS and CSS with the files you downloaded:
   • Copy the Javascript file to static/js/prism.js
   • Copy the CSS file to static/css/prism.css

Navbar

Styling your project logo and name

The default Docsy navbar (.td-navbar) displays your site identity, consisting of the following:

1. Your logo, which is included in the navbar as an inline SVG, styled by .td-navbar .navbar-brand svg. For the style details, see _nav.scss.

   To ensure your logo displays correctly, you may want to resize it and ensure that it doesn’t have height and width attributes so that its size is fully responsive. Override the default styling of .td-navbar .navbar-brand svg or (equivalently) .td-navbar .navbar-brand__logo as needed.

2. Your project name, which is the site title. If you don’t want your project name to appear (for example, because your logo is or contains a wordmark), then add the following custom styling to your project’s styles:

   .td-navbar .navbar-brand__name {
     display: none;
   }
   

Light/dark mode menu

If you enable this feature, Docsy adds a menu to your navbar that lets users switch your site’s documentation page display between a default “light” mode, and a “dark” mode where the text is displayed in a light color on a dark background.

To enable the display of a light/dark mode menu in the navbar, set params.ui.showLightDarkModeMenu to true in your project’s configuration file. The dropdown menu appears at the right, immediately before the search box, if present.

• Configuration file:
• hugo.toml
• hugo.yaml
• hugo.json

[params]
[params.ui]
showLightDarkModeMenu = true

params:
  ui:
    showLightDarkModeMenu: true

{
  "params": {
    "ui": {
      "showLightDarkModeMenu": true
    }
  }
}

Translucent over cover images

For pages containing a blocks/cover shortcode, like most homepages, the navbar is translucent as long as the hero image hasn’t scrolled up past the navbar. For an example, see the About Docsy page. This initial translucent setting ensures that the hero image is maximally visible.

After the hero image has scrolled past the navbar, the navbar’s (opaque) background color is set – usually to the site’s primary color.

The text of navbar entries can be difficult to read with some hero images. In these cases, you can disable navbar translucency by setting the params.ui.navbar_translucent_over_cover_disable option to true in your site’s configuration file.

Tables

Docsy applies the following styles to all tables, through the class .td-table:

• Bootstrap table styles:
  • .table
  • .table-striped
  • .table-responsive
• display: block, which is necessary for tables to be responsive.

This styling configuration gives you responsive tables using Markdown only, without the need to wrap the table in a <div>. It does, however, mean that all your tables have display set to block. If you don’t want this, you can create your own custom styles for tables.

To render a table without Docsy styling, apply the .td-initial class to the table. From the resulting <table> style base, it is easier to apply your own custom styles (rather than trying to undo Docsy table styling), as is illustrated in the following example:

| Shape    | Number of sides |
| -------- | --------------- |
| Triangle | 3               |
| Square   | 4               |
{.td-initial .my-dark-table-style}

The example above uses Markdown attribute syntax, and might render like this:

Customizing templates

Add code to head or before body end

If you need to add some code (CSS import, cookie consent, or similar) to the head section on every page, add the head-end.html partial to your project:

layouts/partials/hooks/head-end.html

And add the code you need in that file. Your partial code is automatically included just before the end of the theme partial head.html. The theme version of head-end.html is empty.

Similarly, if you want to add some code right before the body end, create your own version of the following file:

layouts/partials/hooks/body-end.html

Any code in this file is included automatically at the end of the theme partial scripts.html.

Both head.html and scripts.html are then used to build Docsy’s base page layout, which is used by all the other page templates:

<!doctype html>
<html lang="{{ .Site.Language.Lang }}" class="no-js">
  <head>
    {{ partial "head.html" . }}
  </head>
  <body class="td-{{ .Kind }}">
    <header>
      {{ partial "navbar.html" . }}
    </header>
    <div class="container-fluid td-default td-outer">
      <main role="main" class="td-main">
        {{ block "main" . }}{{ end }}
      </main>
      {{ partial "footer.html" . }}
    </div>
    {{ partialCached "scripts.html" . }}
  </body>
</html>

3 - Navigation and Menus

Docsy provides multiple built-in navigation features for your sites, including site menus, section menus, and page menus. This page shows you how they work and how to configure and customize them to meet your needs.

Top-level menu

The top level menu (the one that appears in the top navigation bar for the entire site) uses your site’s main menu. All Hugo sites have a main menu array of menu entries, accessible via the .Site.Menus site variable and populatable via page front matter or your site’s hugo.toml/hugo.yaml/hugo.json.

To add a page or section to this menu, add it to the site’s main menu in either hugo.toml/hugo.yaml/hugo.json or in the destination page’s front matter (in _index.md or _index.html for a section, as that’s the section landing page). For example, here’s how we added the Documentation section landing page to the main menu in this site:

• Front matter:
• toml
• yaml
• json

+++
title = "Welcome to Docsy"
linkTitle = "Documentation"

[menu.main]
weight = 20
pre = "<i class='fa-solid fa-book'></i>"
+++

---
title: "Welcome to Docsy"
linkTitle: "Documentation"
menu:
  main:
    weight: 20
    pre: <i class='fa-solid fa-book'></i>
---

{
  "title": "Welcome to Docsy",
  "linkTitle": "Documentation",
  "menu": {
    "main": {
      "weight": 20,
      "pre": "<i class='fa-solid fa-book'></i>"
    }
  }
}

The menu is ordered from left to right by page weight. So, for example, a section index or page with weight: 30 would appear after the Documentation section in the menu, while one with weight: 10 would appear before it.

If you want to add a link to an external site to this menu, add it in hugo.toml/hugo.yaml/hugo.json, specifying the weight.

• Configuration file:
• hugo.toml
• hugo.yaml
• hugo.json

[[menu.main]]
    name = "GitHub"
    weight = 50
    url = "https://github.com/quatm/quatm/"

menu:
  main:
    - name: GitHub
      weight: 50
      url: 'https://github.com/quatm/quatm/'

{
  "menu": {
    "main": [
      {
        "name": "GitHub",
        "weight": 50,
        "url": "https://github.com/quatm/quatm/"
      }
    ]
  }
}

Adding icons to the top-level menu

As described in the Hugo docs, you can add icons to the top-level menu by using the pre and/or post parameter for main menu items defined in your site’s hugo.toml/hugo.yaml/hugo.json or via page front matter. For example, the following configuration adds the GitHub icon to the GitHub menu item, and a New! alert to indicate that this is a new addition to the menu.

• Configuration file:
• hugo.toml
• hugo.yaml
• hugo.json

[[menu.main]]
    name = "GitHub"
    weight = 50
    url = "https://github.com/quatm/quatm/"
    pre = "<i class='fa-brands fa-github'></i>"
    post = "<span class='alert'>New!</span>"

menu:
  main:
    - name: GitHub
      weight: 50
      url: 'https://github.com/quatm/quatm/'
      pre: <i class='fa-brands fa-github'></i>
      post: <span class='alert'>New!</span>

{
  "menu": {
    "main": [
      {
        "name": "GitHub",
        "weight": 50,
        "url": "https://github.com/quatm/quatm/",
        "pre": "<i class='fa-brands fa-github'></i>",
        "post": "<span class='alert'>New!</span>"
      }
    ]
  }
}

You can find a complete list of icons to use in the FontAwesome documentation. Docsy includes the free FontAwesome icons by default.

Adding a version drop-down

If you add some [params.versions] in hugo.toml, the Docsy theme adds a version selector drop down to the top-level menu.

You can find out more in the guide to versioning your docs.

Adding a language drop-down

If you configure more than one language in hugo.toml, the Docsy theme adds a language selector drop down to the top-level menu. Selecting a language takes the user to the translated version of the current page, or the home page for the given language.

You can find out more in Multi-language support.

Section menu

The section menu, as shown in the left side of the docs section, is automatically built from the content tree. Like the top-level menu, it is ordered by page or section index weight (or by page creation date if weight is not set), with the page or index’s Title, or linkTitle if different, as its link title in the menu. If a section subfolder has pages other than _index.md or _index.html, those pages will appear as a submenu, again ordered by weight. For example, here’s the metadata for this page showing its weight and title:

• Front matter:
• toml
• yaml
• json

+++
title = "Navigation and Search"
linkTitle = "Navigation and Search"
date = 2017-01-05T00:00:00.000Z
weight = 3
description = '''
Customize site navigation and search for your Docsy site.
'''
+++

---
title: "Navigation and Search"
linkTitle: "Navigation and Search"
date: 2017-01-05
weight: 3
description: >
  Customize site navigation and search for your Docsy site.  
---

{
  "title": "Navigation and Search",
  "linkTitle": "Navigation and Search",
  "date": "2017-01-05T00:00:00.000Z",
  "weight": 3,
  "description": "Customize site navigation and search for your Docsy site.\n"
}

To hide a page or section from the left navigation menu, set toc_hide: true in the front matter.

To hide a page from the section summary on a docs section landing page, set hide_summary: true in the front matter. If you want to hide a page from both the TOC menu and the section summary list, you need to set both toc_hide and hide_summary to true in the front matter.

• Front matter:
• toml
• yaml
• json

+++
title = "My Hidden Page"
weight = 99
toc_hide = true
hide_summary = true
description = '''
Page hidden from both the TOC menu and the section summary list.
'''
+++

---
title: "My Hidden Page"
weight: 99
toc_hide: true
hide_summary: true
description: >
  Page hidden from both the TOC menu and the section summary list.  
---

{
  "title": "My Hidden Page",
  "weight": 99,
  "toc_hide": true,
  "hide_summary": true,
  "description": "Page hidden from both the TOC menu and the section summary list.\n"
}

Section menu options

By default, the section menu shows the current section fully expanded all the way down. This may make the left nav too long and difficult to scan for bigger sites. Try setting site parameter ui.sidebar_menu_compact = true in hugo.toml.

With the compact menu (.ui.sidebar_menu_compact = true), only the current page’s ancestors, siblings and direct descendants are shown. You can use the optional parameter .ui.ul_show to set a desired menu depth to always be visible. For example, with .ui.ul_show = 1 the first menu level is always displayed.

As well as the completely expanded and compact menu options, you can also create a foldable menu by setting the site parameter ui.sidebar_menu_foldable = true in hugo.toml. The foldable menu lets users expand and collapse menu sections by toggling arrow icons beside the section parents in the menu.

On large sites (default: > 2000 pages) the section menu is not generated for each page, but cached for the whole section. The HTML classes for marking the active menu item (and menu path) are then set using JS. You can adjust the limit for activating the cached section menu with the optional parameter .ui.sidebar_cache_limit.

The tabbed pane below lists the menu section options you can define in your project [configuration file].

• Configuration file:
• hugo.toml
• hugo.yaml
• hugo.json

[params.ui]
sidebar_menu_compact = true
ul_show = 1
sidebar_menu_foldable = true
sidebar_cache_limit = 1000

params:
  ui:
    sidebar_menu_compact: true
    ul_show: 1
    sidebar_menu_foldable: true
    sidebar_cache_limit: 1000

{
  "params": {
    "ui": {
      "sidebar_menu_compact": true,
      "ul_show": 1,
      "sidebar_menu_foldable": true,
      "sidebar_cache_limit": 1000,
    }
  }
}

Add icons to the section menu

You can add icons to the section menu in the sidebar by setting the icon parameter in the page front matter (e.g. icon: fa-solid fa-screwdriver-wrench).

You can find a complete list of icons to use in the FontAwesome documentation. Docsy includes the free FontAwesome icons by default.

Out of the box, if you want to use icons, you should define icons for all items on the same menu level in order to ensure an appropriate look. If the icons are used in a different way, individual CSS adjustments are likely necessary.

Add manual links to the section menu

By default the section menu is entirely generated from your section’s pages. If you want to add a manual link to this menu, such as a link to an external site or a page in a different section of your site, you can do this by creating a placeholder page file in the doc hierarchy with the appropriate weight and some special parameters in its metadata (frontmatter) to specify the link details.

To create a placeholder page, create a page file as usual in the directory where you want the link to show up in the menu, and add a manualLink parameter to its metadata. If a page has manualLink in its metadata, Docsy generates a link for it in the section menu for this page and in the section index (the list of the child pages of a section on a landing page - see description in the Docsy docs), but the link destination is replaced by the value of manualLink. The link text is the title (or linkTitle if set) of your placeholder page. You can optionally also set the title attribute of the link with the parameter manualLinkTitle and a link target with manualLinkTarget - for example if you want an external link to open in a new tab you can set the link target to _blank. Docsy automatically adds rel=noopener to links that open new tabs as a security best practice.

You can also use manualLink to add an additional cross reference to another existing page of your site. For internal links you can choose to use the parameter manualLinkRelref instead of manualLink to use the built-in Hugo function relref. If relref can’t find a unique page in your site, Hugo throws a error message.

Breadcrumb navigation

Breadcrumb navigation links appear at the top of each page by default. To disable breadcrumb navigation, set site param ui.breadcrumb_disable = true in hugo.toml.

Breadcrumb navigation links are also shown for each item on the taxonomy results page (i.e. when you click one of the taxonomy labels, e.g. Tags/Categories). These breadcrumbs can be disabled in hugo.toml by setting site param ui.taxonomy_breadcrumb_disable = true.

The tabbed pane below lists the breadcrumb navigation options you can define in your project [configuration file].

• Configuration file:
• hugo.toml
• hugo.yaml
• hugo.json

[params.ui]
breadcrumb_disable = true
taxonomy_breadcrumb_disable = true

params:
  ui:
    breadcrumb_disable: true
    taxonomy_breadcrumb_disable: true

{
  "params": {
    "ui": {
      "breadcrumb_disable": true,
      "taxonomy_breadcrumb_disable": true
    }
  }
}

Heading self links

Docsy supports build-time generation of heading self links using Hugo’s render-heading.html hook.

To enable this feature in your project, define layouts/_default/_markup/render-heading.html as:

{{ template "_default/_markup/td-render-heading.html" . }}

The heading self-link anchor class is .td-heading-self-link, which you can customize for your project. By default, the heading self-link style has these defaults:

• The self-link symbol is #.
• The symbol is always visible on mobile and touch devices, otherwise it is only visible on hover or focus.

Your projects can also reuse (in your own custom heading render hook) or override the heading self-link template _default/_markup/_td-heading-self-link.html, which is defined in layouts/_default/_markup/td-render-heading.html.

4 - Search

Docsy offers multiple options that let your readers search your site content, so you can pick one that suits your needs. You can choose from:

• Google Custom Search Engine (GCSE), the default option, which uses Google’s index of your public site to generate a search results page.
• Algolia DocSearch, which uses Algolia’s indexing and search mechanism. Search results are displayed as a pop-up. Algolia DocSearch is free for public documentation sites.
• Local search with Lunr, which uses Javascript to index and search your site without the need to connect to external services. This option doesn’t require your site to be public.

If you enable any of these search options in your project configuration file, a search box displays in the right of your top navigation bar. By default a search box also displays at the top of the section menu in the left navigation pane, which you can disable if you prefer, or if you’re using a search option that only works with the top search box.

Disabling the sidebar search box

By default, the search box appears in both the top navigation bar and at the top of the sidebar left navigation pane. If you don’t want the sidebar search box, set the site parameter sidebar_search_disable to true in hugo.toml/hugo.yaml/hugo.json:

• Configuration file:
• hugo.toml
• hugo.yaml
• hugo.json

[params.ui]
sidebar_search_disable = true

params:
  ui:
    sidebar_search_disable: true

{
  "params": {
    "ui": {
      "sidebar_search_disable": true
    }
  }
}

Configure search with a Google Custom Search Engine

By default Docsy uses a Google Custom Search Engine (GCSE) to search your site. To enable this feature, you’ll first need to make sure that you have built and deployed a production version of your site, as otherwise your site won’t be crawled and indexed.

Setting up site search

1. Create a Google Custom Search Engine for your deployed site by clicking New search engine on the Custom Search page and following the instructions. Make a note of the ID for your new search engine.

2. Add any further configuration you want to your search engine using the Edit search engine options. In particular you may want to do the following:

   • Select Look and feel. Change from the default Overlay layout to Results only, as this option means your search results are embedded in your search page rather than appearing in a separate box. Click Save to save your changes.
   • Edit the default result link behavior so that search results from your site don’t open in a new tab. To do this, select Search Features - Advanced - Websearch Settings. In the Link Target field, type “_parent”. Click Save to save your changes.

Adding the search page

Once you have your search engine set up, you can add the feature to your site:

1. Ensure you have a Markdown file in content/en/search.md (and one per other languages if needed) to display your search results. It only needs a title and layout: search, as in the following example:

   • Front matter:
   • toml
   • yaml
   • json

   +++
   title = "Search Results"
   layout = "search"
   +++

   ---
   title: Search Results
   layout: search
   ---

   {
       "title": "Search Results",
       "layout": "search"
   }

2. Add your Google Custom Search Engine ID to the site params in hugo.toml/hugo.yaml/hugo.json. You can add different values per language if needed.

   • Configuration file:
   • hugo.toml
   • hugo.yaml
   • hugo.json

   [params]
   # Google Custom Search Engine ID. Remove or comment out to disable search.
   gcs_engine_id = "011737558837375720776:fsdu1nryfng"

   params:
     gcs_engine_id: 011737558837375720776:fsdu1nryfng

   {
     "params": {
       "gcs_engine_id": "011737558837375720776:fsdu1nryfng"
     }
   }

Disabling GCSE search

If you don’t specify a Google Custom Search Engine ID for your project and haven’t enabled any other search options, the search box won’t appear in your site. If you’re using the default hugo.toml from the example site and want to disable search, just comment out or remove the relevant line.

Algolia DocSearch

As an alternative to GCSE, you can use Algolia DocSearch, which is free for public documentation sites. Docsy supports Algolia DocSearch v3.

Sign up for Algolia DocSearch

Complete the form at https://docsearch.algolia.com/apply. Proceed to the next step once you’ve received Algolia DocSearch parameters for your project.

Eager to test DocSearch?

Docsy defaults to the Algolia test-site parameters when none are provided. To enable search over the Algolia test, define params.search.algolia without any other fields, as outlined next.

Configure Algolia DocSearch

1. Ensure that GCSE search is disabled.

2. Add your project’s Algolia DocSearch parameters to hugo.toml/hugo.yaml/hugo.json, for example (using Algolia test values):

   • Configuration file:
   • hugo.toml
   • hugo.yaml
   • hugo.json

   [params.search.algolia]
   appId = "R2IYF7ETH7"
   apiKey = "599cec31baffa4868cae4e79f180729b"
   indexName = "docsearch"

   params:
     search:
       algolia:
         appId: R2IYF7ETH7
         apiKey: 599cec31baffa4868cae4e79f180729b
         indexName: docsearch

   {
     "params": {
       "search": {
         "algolia": {
           "appId": "R2IYF7ETH7",
           "apiKey": "599cec31baffa4868cae4e79f180729b",
           "indexName": "docsearch"
         }
       }
     }
   }

To learn more about Algolia DocSearch V3, see Getting started.

When you’ve completed these steps, Algolia search should be enabled on your site. Search results are displayed as a pop-up, so you don’t need to add any search results page.

Customizing Algolia templates

You can customize or disable Docsy’s default Algolia support by creating the following template files:

• layouts/partials/algolia/head.html used by head.html to load Algolia DocSearch styles. It also issues a deprecation warning for params.algolia_docsearch.
• layouts/partials/algolia/scripts.html used by scripts.html to load and configure Algolia DocSearch.

Leave either file empty to disable Docsy’s implementation.

Local search with Lunr

Lunr is a Javascript-based search option that lets you index your site and make it searchable without the need for external, server-side search services. This is a good option particularly for smaller or non-public sites.

To add Lunr search to your Docsy site:

1. Enable local search in hugo.toml/hugo.yaml/hugo.json.

   • Configuration file:
   • hugo.toml
   • hugo.yaml
   • hugo.json

   [params]
   offlineSearch = true

   params:
     offlineSearch: true

   {
     "params": {
       "offlineSearch": true
     }
   }

2. Remove or comment out any GCSE ID in hugo.toml/hugo.yaml/hugo.json and ensure Algolia DocSearch is set to false, as you can only have one type of search enabled. See Disabling GCSE search.

Once you’ve completed these steps, local search is enabled for your site and results appear in a drop down when you use the search box.

Changing the summary length of the local search results

You can customize the summary length by setting offlineSearchSummaryLength in hugo.toml/hugo.yaml/hugo.json.

• Configuration file:
• hugo.toml
• hugo.yaml
• hugo.json

#Enable offline search with Lunr.js
[params]
offlineSearch = true
offlineSearchSummaryLength = 200

params:
  offlineSearch: true
  offlineSearchSummaryLength: 200

{
  "params": {
    "offlineSearch": true,
    "offlineSearchSummaryLength": 200
  }
}

Changing the maximum result count of the local search

You can customize the maximum result count by setting offlineSearchMaxResults in hugo.toml/hugo.yaml/hugo.json.

• Configuration file:
• hugo.toml
• hugo.yaml
• hugo.json

[params]
offlineSearch = true
offlineSearchMaxResults = 25

params:
  offlineSearch: true
  offlineSearchMaxResults: 25

{
  "params": {
    "offlineSearch": true,
    "offlineSearchMaxResults": 25
  }
}

Changing the width of the local search results popover

The width of the search results popover will automatically widen according to the content.

If you want to limit the width, add the following scss into assets/scss/_variables_project.scss.

.td-offline-search-results {
  max-width: 460px;
}

Excluding pages from local search results

To exclude pages from local search results, add exclude_search: true to the the frontmatter of each page:

• Front matter:
• toml
• yaml
• json

+++
title = "Index"
weight = 10
exclude_search = true
+++

---
title: "Index"
weight: 10
exclude_search: true
---

{
  "title": "Index",
  "weight": 10,
  "exclude_search": true
}

5 - Doc Versioning

Depending on your project’s releases and versioning, you may want to let your users access previous versions of your documentation. How you deploy the previous versions is up to you. This page describes the Docsy features that you can use to provide navigation between the various versions of your docs and to display an information banner on the archived sites.

Adding a version drop-down menu

If you add some [params.versions] in hugo.toml/hugo.yaml/hugo.json, the Docsy theme adds a version selector drop down to the top-level menu. You specify a URL and a name for each version you would like to add to the menu, as in the following example:

• Configuration file:
• hugo.toml
• hugo.yaml
• hugo.json

# Add your release versions here
[[params.versions]]
  version = "master"
  url = "https://master.kubeflow.org"

[[params.versions]]
  version = "v0.2"
  url = "https://v0-2.kubeflow.org"

[[params.versions]]
  version = "v0.3"
  url = "https://v0-3.kubeflow.org"

params:
  versions:
    - version: master
      url: 'https://master.kubeflow.org'
    - version: v0.2
      url: 'https://v0-2.kubeflow.org'
    - version: v0.3
      url: 'https://v0-3.kubeflow.org'

{
  "params": {
    "versions": [
      {
        "version": "master",
        "url": "https://master.kubeflow.org"
      },
      {
        "version": "v0.2",
        "url": "https://v0-2.kubeflow.org"
      },
      {
        "version": "v0.3",
        "url": "https://v0-3.kubeflow.org"
      }
    ]
  }
}

Remember to add your current version so that users can navigate back!

The default title for the version drop-down menu is Releases. To change the title, change the site parameter version_menu in hugo.toml/hugo.yaml/hugo.json:

• Configuration file:
• hugo.toml
• hugo.yaml
• hugo.json

[params]
version_menu = "Releases"

params:
  version_menu: Releases

{
  "params": {
    "version_menu": "Releases"
  }
}

If you set the version_menu_pagelinks parameter to true, then links in the version drop-down menu point to the current page in the other version, instead of the main page. This can be useful if the document doesn’t change much between the different versions. Note that if the current page doesn’t exist in the other version, the link will be broken.

You can read more about Docsy menus in the guide to navigation and search.

Displaying a banner on archived doc sites

If you create archived snapshots for older versions of your docs, you can add a note at the top of every page in the archived docs to let readers know that they’re seeing an unmaintained snapshot and give them a link to the latest version.

For example, see the archived docs for Kubeflow v0.6:

To add the banner to your doc site, make the following changes in your hugo.toml/hugo.yaml/hugo.json file:

1. Set the site parameter archived_version to true:

   • Configuration file:
   • hugo.toml
   • hugo.yaml
   • hugo.json

   [params]
   archived_version = true

   params:
     archived_version: true

   {
     "params": {
       "archived_version": true
     }
   }

2. Set the site parameter version to the version of the archived doc set. For example, if the archived docs are for version 0.1:

   • Configuration file:
   • hugo.toml
   • hugo.yaml
   • hugo.json

   [params]
   version = "0.1"

   params:
     version: 0.1

   {
     "params": {
       "version": "0.1"
     }
   }

3. Make sure that site parameter url_latest_version contains the URL of the website that you want to point readers to. In most cases, this should be the URL of the latest version of your docs:

   • Configuration file:
   • hugo.toml
   • hugo.yaml
   • hugo.json

   [params]
   url_latest_version = "https://your-latest-doc-site.com"

   params:
     url_latest_version: https://your-latest-doc-site.com

   {
     "params": {
       "url_latest_version": "https://your-latest-doc-site.com"
     }
   }

6 - Docsy Shortcodes

Rather than writing all your site pages from scratch, Hugo lets you define and use shortcodes. These are reusable snippets of content that you can include in your pages, often using HTML to create effects that are difficult or impossible to do in simple Markdown. Shortcodes can also have parameters that let you, for example, add your own text to a fancy shortcode text box. As well as Hugo’s built-in shortcodes, Docsy provides some shortcodes of its own to help you build your pages.

Shortcode delimiters

As illustrated below, using the bracket styled shortcode delimiter, {{<...>}}, tells Hugo that the inner content is HTML/plain text and needs no further processing. By using the delimiter {{%...%}}, Hugo will treat the shortcode body as Markdown. You can use both styles in your pages.

Shortcode blocks

The theme comes with a set of custom Page Block shortcodes that can be used to compose landing pages, about pages, and similar.

These blocks share some common parameters:

height

A pre-defined height of the block container. One of min, med, max, full, or auto. Setting it to full will fill the Viewport Height, which can be useful for landing pages.

color

The block will be assigned a color from the theme palette if not provided, but you can set your own if needed. You can use all of Bootstrap’s color names, theme color names or a grayscale shade. Some examples would be primary, white, dark, warning, light, success, 300, blue, orange. This will become the background color of the block, but text colors will adapt to get proper contrast.

blocks/cover

The blocks/cover shortcode creates a landing page type of block that fills the top of the page.

{{< blocks/cover title="Welcome!" image_anchor="center" height="full" color="primary" >}}
<div class="mx-auto">
	<a class="btn btn-lg btn-primary me-3 mb-4" href="{{< relref "/docs" >}}">
		Learn More <i class="fa-solid fa-circle-right ms-2"></i>
	</a>
	<a class="btn btn-lg btn-secondary me-3 mb-4" href="https://example.org">
		Download <i class="fa-brands fa-github ms-2"></i>
	</a>
	<p class="lead mt-5">This program is now available in <a href="#">AppStore!</a></p>
	<div class="mx-auto mt-5">
		{{< blocks/link-down color="info" >}}
	</div>
</div>
{{< /blocks/cover >}}

Note that the relevant shortcode parameters above will have sensible defaults, but is included here for completeness.

To set the background image, place an image with the word “background” in the name in the page’s Page Bundle. For example, in our the example site the background image in the home page’s cover block is featured-background.jpg, in the same directory.

For available icons, see Font Awesome.

blocks/lead

The blocks/lead block shortcode is a simple lead/title block with centred text and an arrow down pointing to the next section.

{{% blocks/lead color="dark" %}}
TechOS is the OS of the future.

Runs on **bare metal** in the **cloud**!
{{% /blocks/lead %}}

blocks/section

The blocks/section shortcode is meant as a general-purpose content container. It comes in two “flavors”, one for general content and one with styling more suitable for wrapping a horizontal row of feature sections.

The example below shows a section wrapping 3 feature sections.

{{< blocks/section color="dark" type="row" >}}
{{% blocks/feature icon="fa-lightbulb" title="Fastest OS **on the planet**!" %}}
The new **TechOS** operating system is an open source project. It is a new project, but with grand ambitions.
Please follow this space for updates!
{{% /blocks/feature %}}
{{% blocks/feature icon="fa-brands fa-github" title="Contributions welcome!" url="https://github.com/gohugoio/hugo" %}}

blocks/feature

{{% blocks/feature icon="fa-brands fa-github" title="Contributions welcome!" url="https://github.com/gohugoio/hugo" %}}
We do a [Pull Request](https://github.com/gohugoio/hugo/pulls) contributions workflow on **GitHub**. New users are always welcome!
{{% /blocks/feature %}}

blocks/link-down

The blocks/link-down shortcode creates a navigation link down to the next section. It’s meant to be used in combination with the other blocks shortcodes.

<div class="mx-auto mt-5">
	{{< blocks/link-down color="info" >}}
</div>

Shortcode helpers

alert

The alert shortcode creates an alert block that can be used to display notices or warnings.

{{% alert title="Warning" color="warning" %}}
This is a warning.
{{% /alert %}}

Renders to:

pageinfo

The pageinfo shortcode creates a text box that you can use to add banner information for a page: for example, letting users know that the page contains placeholder content, that the content is deprecated, or that it documents a beta feature.

{{% pageinfo color="info" %}}
This is placeholder content.
{{% /pageinfo %}}

Renders to:

imgproc

The imgproc shortcode finds an image in the current Page Bundle and scales it given a set of processing instructions.

{{% imgproc spruce Fill "400x450" %}}
Norway Spruce *Picea abies* shoot with foliage buds.
{{% /imgproc %}}

Use the syntax above if the inner content and/or the byline parameter of your shortcode is authored in markdown. In case of HTML content, use <> as innermost delimiters: {{< imgproc >}}<b>HTML</b> content{{< /imgproc >}}.

The example above has also a byline with photo attribution added. When using illustrations with a free license from WikiMedia and similar, you will in most situations need a way to attribute the author or licensor. You can add metadata to your page resources in the page front matter. The byline param is used by convention in this theme:

• Front matter:
• toml
• yaml
• json

+++
[[resources]]
src = "**spruce*.jpg"

  [resources.params]
  byline = "*Photo*: Bjørn Erik Pedersen / CC-BY-SA"
+++

---
resources:
- src: "**spruce*.jpg"
  params:
    byline: "*Photo*: Bjørn Erik Pedersen / CC-BY-SA"
---

{
  "resources": [
    {
      "src": "**spruce*.jpg",
      "params": {
        "byline": "*Photo*: Bjørn Erik Pedersen / CC-BY-SA"
      }
    }
  ]
}

swaggerui

You can place the swaggerui shortcode anywhere inside a page with the swagger layout; it renders Swagger UI using any OpenAPI YAML or JSON file as source. This file can be hosted anywhere you like, for example in your site’s root /static folder.

• Front matter:
• toml
• yaml
• json

+++
title = "Pet Store API"
type = "swagger"
weight = 1
description = "Reference for the Pet Store API"
+++

{{< swaggerui src="/openapi/petstore.yaml" >}}

---
title: "Pet Store API"
type: swagger
weight: 1
description: Reference for the Pet Store API
---

{{< swaggerui src="/openapi/petstore.yaml" >}}

{
  "title": "Pet Store API",
  "type": "swagger",
  "weight": 1,
  "description": "Reference for the Pet Store API"
}

{{< swaggerui src="/openapi/petstore.yaml" >}}

You can customize Swagger UI’s look and feel by overriding Swagger’s CSS in themes/docsy/assets/scss/_swagger.scss.

redoc

The redoc shortcode uses the open-source Redoc tool to render reference API documentation from an OpenAPI YAML or JSON file. This can be hosted anywhere you like, for example in your site’s root /static folder, but you can use a URL as well, for example:

---
title: "Pet Store API"
type: docs
weight: 1
description: Reference for the Pet Store API
---

{{< redoc "https://raw.githubusercontent.com/OAI/OpenAPI-Specification/main/examples/v2.0/yaml/petstore.yaml" >}}

iframe

With this shortcode you can embed external content into a Docsy page as an inline frame (iframe) - see: https://www.w3schools.com/tags/tag_iframe.asp

Tabbed panes

Sometimes it’s very useful to have tabbed panes when authoring content. One common use-case is to show multiple syntax highlighted code blocks that showcase the same problem, and how to solve it in different programming languages. As an example, the tabbed pane below shows the language-specific variants of the famous Hello world! program one usually writes first when learning a new programming language:

• C
• C++
• Go
• Java
• Kotlin
• Lua
• PHP
• Python
• Ruby
• Scala

#include <stdio.h>
#include <stdlib.h>

int main(void)
{
  puts("Hello World!");
  return EXIT_SUCCESS;
}

#include <iostream>

int main()
{
  std::cout << "Hello World!" << std::endl;
}

package main
import "fmt"
func main() {
  fmt.Printf("Hello World!\n")
}

class HelloWorld {
  static public void main( String args[] ) {
    System.out.println( "Hello World!" );
  }
}

fun main(args : Array<String>) {
    println("Hello, world!")
}

print "Hello world"

<?php
echo 'Hello World!';
?>

print("Hello World!")

puts "Hello World!"

object HelloWorld extends App {
  println("Hello world!")
}

The Docsy template provides two shortcodes tabpane and tab that let you easily create tabbed panes. To see how to use them, have a look at the following code block, which renders to a right aligned pane with one disabled and three active tabs:

{{< tabpane text=true right=true >}}
  {{% tab header="**Languages**:" disabled=true /%}}
  {{% tab header="English" lang="en" %}}
  ![Flag United Kingdom](flags/uk.png)
  Welcome!
  {{% /tab %}}
  {{< tab header="German" lang="de" >}}
    <b>Herzlich willkommen!</b>
    <img src="flags/de.png" alt="Flag Germany" style="float: right; padding: 0 0 0 0px">
  {{< /tab >}}
  {{% tab header="Swahili" lang="sw" %}}
  ![Flag Tanzania](flags/tz.png)
  **Karibu sana!**
  {{% /tab %}}
{{< /tabpane >}}

This code translates to the right aligned tabbed pane below, showing a Welcome! greeting in English, German or Swahili:

• Languages:
• English
• German
• Swahili

Welcome!

Herzlich willkommen!

Karibu sana!

Shortcode details

Tabbed panes are implemented using two shortcodes: tabpane containing two or more nested tabs.

tabpane

The tabpane shortcode, which is the container element for the tabs, supports the following named parameters, all of which are optional:

• lang: the default code-block language to use for all contained tabs
• highlight: parameter passed on to the code-block highlight function, as described below
• langEqualsHeader: set to true when header text matches the tab language.
• persist: one of header, lang, or disabled
• persistLang: deprecated, use persist instead
• right: set to true if you want right-aligned tabs
• text: set to true if the content of all contained tabs are text. Default is false and assumes the content is code.

The value of the optional parameters lang and highlight are passed on as second LANG and third OPTIONS arguments to Hugo’s built-in highlight function, which is used to render the code blocks of the individual tabs.

Tab selection is persisted by default. When unspecified, persist defaults to header when text=true or lang is set; otherwise persist defaults to lang. To disable tab persistence, set persist=disable.

tab

The tab shortcode represent the tabs you want to show. It supports the following named parameters, all of which are optional:

• header: defines the tab’s header text. When omitted it defaults to text of the form “Tab n”. You can omit the parameter name if it is the only tab parameter:

  {{< tab "My tab header" >}} … {{< /tab >}}
  

• lang: code-block language for code tabs
• highlight: parameter passed on to the code-block highlight function
• right: set to true in order to split tab panes into a left aligned and a right aligned tab groups. Specify right=true in the dividing tab. By using right=true more than once, you can even render multiple tab groups.
• disabled: set to true to disable a tab.
• text: set to true for text tabs. By default tabs are assumed to contain code.

For enabled tabs, there are two modes for content display, code representation and textual representation:

• By default, the tab’s content is rendered as a code block. In order to get proper syntax highlighting, specify the named parameter lang –and optionally the parameter highlight– for each tab. Parameters set in the parent tabpane shortcode will be overwritten.
• If the contents of your tabs should be rendered as text with different styles and optional images, specify text=true as parameter of your tab:

Reminder: If your content is markdown, use the percent sign % as delimiter for your tab shortcode, like this:

{{% tab %}} Your \*\*markdown\*\* content {{% /tab %}}

Card panes

When authoring content, it’s sometimes very useful to put similar text blocks or code fragments on card like elements, which can be optionally presented side by side. Let’s showcase this feature with the following sample card group which shows the first four Presidents of the United States:

George Washington

*1732     †1799

President: 1789 – 1797

John Adams

* 1735     † 1826

President: 1797 – 1801

Thomas Jefferson

* 1743     † 1826

President: 1801 – 1809

James Madison

* 1751     † 1836

President: 1809 – 1817

Docsy supports creating such card panes via different shortcodes:

• The cardpane shortcode which is the container element for the various cards to be presented.
• The card shortcodes, with each shortcode representing an individual card. While cards are often presented inside a card group, a single card may stand on its own, too. A card shortcode can hold programming code, text, images or any other arbitrary kind of markdown or HTML markup as content. In case of programming code, cards provide automatic code-highlighting and other optional features like line numbers, highlighting of certain lines, ….

Shortcode card: textual content

Make use of the card shortcode to display a card. The following code sample demonstrates how to code a card element:

{{< card header="**Imagine**" title="Artist and songwriter: John Lennon" subtitle="Co-writer: Yoko Ono"
          footer="![SignatureJohnLennon](https://server.tld/…/signature.png 'Signature John Lennon')">}}
Imagine there's no heaven, It's easy if you try<br/>
No hell below us, above us only sky<br/>
Imagine all the people living for today…

…
{{< /card >}}

This code translates to the left card shown below, showing the lyrics of John Lennon’s famous song Imagine. A second explanatory card element to the right indicates and explains the individual components of a card:
