Helpers

You can think of these Jekyll helpers as little shortcuts. Since GitHub Pages doesn’t allow most plugins — custom tags are out. Instead the theme leverages includes to do something similar.

Base Path

Deprecated. Use relative_url filter instead.

Instead of repeating {{ site.url }}{{ site.baseurl }} over and over again to create absolute URLs, you can use {{ base_path }} instead. Simply add {% include base_path %} to layouts, posts, pages, collections, or other includes and you’re good to go.

ProTip: It’s a good practice to use absolute URL paths for assets (especially post images) so they correctly resolve in the site’s XML feeds. Example: {{ "/assets/images/filename.jpg" | relative_url }} ~> https://yourdoamin.com/assets/images/filename.jpg

Group by Array

Jekyll Group-By-Array by Max White.

A liquid include file for Jekyll that allows an object to be grouped by an array.

Figure

Generate a <figure> element with a single image and caption.

Include Parameter	Required	Description
image_path	Required	Full path to image eg: `/assets/images/filename.jpg`. Use absolute URLS for those hosted externally.
alt	Optional	Alternate text for image.
caption	Optional	Figure caption text. Markdown is allowed.

Using the figure include like so:

{% include figure image_path="/assets/images/unsplash-image-10.jpg" alt="this is a placeholder image" caption="This is a figure caption." %}

Will output the following:

this is a placeholder image — This is a figure caption.

<figure>
  <img src="/assets/images/unsplash-image-10.jpg" alt="this is a placeholder image">
  <figcaption>This is a figure caption.</figcaption>
</figure>

Gallery

Generate a <figure> element with optional caption of arrays with two or more images.

To place a gallery add the necessary YAML Front Matter.

Name	Required	Description
url	Optional	URL to link gallery image to (eg. a larger detail image).
image_path	Required	Full path to image eg: `/assets/images/filename.jpg`. Use absolute URLS for those hosted externally.
alt	Optional	Alternate text for image.
title	Optional	Title text for image. Will display as a caption in a Magnific Popup overlay when linked to a larger image with `url`.

gallery:
  - url: /assets/images/unsplash-gallery-image-1.jpg
    image_path: /assets/images/unsplash-gallery-image-1-th.jpg
    alt: "placeholder image 1"
    title: "Image 1 title caption"
  - url: /assets/images/unsplash-gallery-image-2.jpg
    image_path: /assets/images/unsplash-gallery-image-2-th.jpg
    alt: "placeholder image 2"
    title: "Image 2 title caption"
  - url: /assets/images/unsplash-gallery-image-3.jpg
    image_path: /assets/images/unsplash-gallery-image-3-th.jpg
    alt: "placeholder image 3"
    title: "Image 3 title caption"

And then drop-in the gallery include in the body where you’d like it to appear.

Include Parameter	Required	Description	Default
id	Optional	To add multiple galleries to a document uniquely name them in the YAML Front Matter and reference in `{% include gallery id="gallery_id" %}`	`gallery`
class	Optional	Use to add a `class` attribute to the surrounding `<figure>` element for additional styling needs.
caption	Optional	Gallery caption description. Markdown is allowed.

{% include gallery caption="This is a sample gallery with **Markdown support**." %}

Gallery example with caption:

placeholder image 1 — This is a sample gallery with **Markdown support**.

placeholder image 2 — This is a sample gallery with **Markdown support**.

Feature Row

Designed to compliment the splash page layout as a way of arranging and aligning “feature blocks” containing text or image.

To add a feature row containing three content blocks with text and image, add the following YAML Front Matter

Name	Required	Description	Default
image_path	Required	Full path to image eg: `/assets/images/filename.jpg`. Use absolute URLS for those hosted externally.
image_caption	Optional	Caption for image, Markdown is supported eg: `“Image from Unsplash”
alt	Optional	Alternate text for image.
title	Optional	Content block title.
excerpt	Optional	Content block excerpt text. Markdown is allowed.
url	Optional	URL that the button should link to.
btn_label	Optional	Button text label.	`more_label` in UI Text data file.
btn_class	Optional	Button style. See utility classes for options.	`btn`

feature_row:
  - image_path: /assets/images/unsplash-gallery-image-1-th.jpg
    alt: "placeholder image 1"
    title: "Placeholder 1"
    excerpt: "This is some sample content that goes here with **Markdown** formatting."
  - image_path: /assets/images/unsplash-gallery-image-2-th.jpg
    alt: "placeholder image 2"
    title: "Placeholder 2"
    excerpt: "This is some sample content that goes here with **Markdown** formatting."
    url: "#test-link"
    btn_label: "Read More"
    btn_class: "btn--inverse"
  - image_path: /assets/images/unsplash-gallery-image-3-th.jpg
    title: "Placeholder 3"
    excerpt: "This is some sample content that goes here with **Markdown** formatting."

And then drop-in the feature row include in the body where you’d like it to appear.

Include Parameter	Required	Description	Default
id	Optional	To add multiple rows to a document uniquely name them in the YAML Front Matter and reference in `{% include feature_row id="row2" %}`	`feature_row`
type	Optional	Alignment of the featured blocks in the row. Options include: `left`, `center`, or `right` aligned.

{% include feature_row %}

Placeholder 1

This is some sample content that goes here with Markdown formatting.

Placeholder 2

This is some sample content that goes here with Markdown formatting.

Placeholder 3

This is some sample content that goes here with Markdown formatting.

Responsive Video Embed

Embed a video from YouTube or Vimeo that responsively sizes to fit the width of its parent.

Parameter	Required	Description
`id`	Required	ID of the video
`provider`	Required	Hosting provider of the video, either `youtube` or `vimeo`

YouTube

To embed the following YouTube video at url https://www.youtube.com/watch?v=XsxDH4HcOWA (long version) or https://youtu.be/XsxDH4HcOWA (short version) into a post or page’s main content you’d use:

{% include video id="XsxDH4HcOWA" provider="youtube" %}

To embed it as a video header you’d use the following YAML Front Matter

header:
  video:
    id: XsxDH4HcOWA
    provider: youtube

Vimeo

To embed the following Vimeo video at url https://vimeo.com/212731897 into a post or page’s main content you’d use:

{% include video id="212731897" provider="vimeo" %}

To embed it as a video header you’d use the following YAML Front Matter

header:
  video:
    id: 212731897
    provider: vimeo

Auto-generated table of contents list for your posts and pages can be enabled using two methods.

table of contents example

Enabled via YAML Front Matter

Add toc: true to the YAML Front Matter of any post or page.

Parameter	Required	Description	Default
toc	Optional	Show table of contents. (boolean)	`false`
toc_label	Optional	Table of contents title. (string)	`toc_label` in UI Text data file.
toc_icon	Optional	Table of contents icon, displays before the title. (string)	Font Awesome file-alt icon. Other FA icons can be used instead.
toc_sticky	Optional	Stick table of contents to top of screen.	`false`

TOC example with custom title and icon

---
toc: true
toc_label: "My Table of Contents"
toc_icon: "cog"
---

Note: using both methods will have unintended results. Be sure to remove {% include toc %} placed table of contents from your content when using toc: true.

Enabled via `toc` include (deprecated)

To include a Kramdown auto-generated table of contents for posts and pages, add the following helper to your content.

{% include toc %}

Note: this method only works with Markdown files.

Deprecated: toc helper will be removed in the next major version of the theme. It is encouraged that you migrate to the YAML Front Matter method above.

Parameter	Required	Description	Default
title	Optional	Table of contents title. (string)	`toc_label` in UI Text data file.
icon	Optional	Table of contents icon, displays before the title. (string)	Font Awesome file-alt icon. Other FA icons can be used instead.

TOC example with custom title and icon

{% include toc icon="cog" title="My Table of Contents" %}

Include an unordered list of links to be used as sidebar navigation with the nav_list helper.

1. Start by adding a set of titles and URLs to _data/navigation.yml in the same way the main navigation is built.

foo navigation example:

# _data/navigation.yml
foo:
  - title: "Link 1 Title"
    url: /link-1-page-url/

  - title: "Link 2 Title"
    url: http://external-link.com

  - title: "Link 3 Title"
    url: /link-3-page-url/

  - title: "Link 4 Title"
    url: /link-4-page-url/

For a navigation list that has child pages you’d structure the YAML like this:

# _data/navigation.yml
foo:
  - title: "Parent Link 1"
    url: /parent-1-page-url/
    children:
      - title: "Child Link 1"
        url: /child-1-page-url/
      - title: "Child Link 2"
        url: /child-2-page-url/

  - title: "Parent Link 2"
    url: /parent-2-page-url/
    children:
      - title: "Child Link 1"
        url: /child-1-page-url/
      - title: "Child Link 2"
        url: /child-2-page-url/
      - title: "Child Link 3"
        url: /child-3-page-url/

2: On the page(s) you’d like the foo sidebar nav add the following YAML Front Matter, referencing the same key name.

sidebar:
  nav: "foo"

ProTip: If you’re applying the same navigation list to several pages setting it as a Front Matter default is the better option.

The theme’s documentation is built with the nav_list helper so if you’d like an example to dissect take a look at navigation.yml, _config.yml and _doc collection in the /docs/ folder of this repo.

To add a navigation list to a post or page’s main content instead of the sidebar use the include this way:

{% include nav_list nav="foo" %}

Parameter	Required	Description
items	Required	Name of the links array found in `_data/navigation.yml`.
