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 absolute_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" | absolute_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.

The Liquid based taxonomy archives found amongst the demo pages rely on this helper.

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>

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 placeholder image 2 placeholder image 3
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.  
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 image 1

Table of Contents

To include an auto-generated table of contents for posts and pages, add the following helper before any actual content in your post or page.

{% include toc %}

table of contents example

Parameter Required Description Default
title Optional Table of contents title. toc_label in UI Text data file.
icon Optional Table of contents icon (shows before the title). Font Awesome file-text icon. Any other FA icon can be used instead.

TOC example with custom title and icon

{% include toc icon="gears" 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(https://github.com/mmistakes/minimal-mistakes/tree/master/docs/) 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.
