Configure Type on Strap šŸ› 

Open _config.yml in a text editor to change most of the blog's settings.

If a variable in this document is marked as "optional", disable the feature by removing all text from the variable.

Site configuration

Base url

Configure Jekyll as your own blog or with a "baseurl" in _config.yml:

Jekyll website without a "baseurl" (such as a GitHub Pages website with your username as the repository name):

baseurl: ""
url: "https://username.github.io"

Jekyll website with "baseurl" (like the Type on Strap demo page):

baseurl: "/sub-directory"
url: "https://username.github.io"

Jekyll blog configuration

And here is the basic information you will need in your _config.yml for it to work properly:

post_navigation: true
paginate: 10
paginate_path: "blog/page:num"
plugins: [jekyll-paginate, jekyll-seo-tag, jekyll-feed]

To configure the blog part and default plugins. Those plugins are validated by GitHub page.

Meta and Branding

Meta variables hold basic information about your Jekyll site, which will be used throughout the site and as meta properties that are used for search engines, browsers, and the site's RSS feed.

Change these variables in _config.yml:

title: My Jekyll Blog                 # Name of website
avatar: assets/img/avatar.png         # Path of avatar image, to be displayed in the theme's header
description: My blog posts            # Short description, primarily used by search engines
favicon: assets/favicon.ico           # Icon displayed in the tab
color_theme: auto                     # color theme auto, dark or light

You can also customize the seo tags default option following the jekyll-seo-tag plugin documentation. The color theme can be set to dark or light (customize it in variables.scss). Using auto you'll have a tiny icon in the navbar allowing the use to manually switch from dark to light theme.

Theme customization šŸŽØ

Customize your site header/footer with these variables in _config.yml:

header_text: Welcome to my Jekyll blog
footer_text: Copyright 2017

If you don't want anything, replace the value by " ".

Header's image

The header's image (tested with 2480x1280) can be set as one image with header_feature_image but can also be responsive:

header_feature_image: assets/img/header/my-header-image.png
header_feature_image_responsive: true

By setting header_feature_image_responsive to true, it will look for images with suffix -small (620x320) and -medium (1240x640) to display on smaller screen.

Localisation string

Localization string is a way to quickly change the template language for text like Next Post or Follow on, ... You can find all the properties in _data/language.yml.

By default, it is in English, but you can easily add your own language.

Here you also can set the date format, e.g., set str_date_format: '%B %-d, %Y' for "January, 13, 2024", str_date_format: '%Y-%m-%d' for 2024-01-13, or str_date_format: '%d.%m.%Y' for 13.01.2024.

Google Analytics

To enable Google Analytics (GA4), add your Measurement ID to _config.yml like so:

google_analytics: G-XXXXXXXXXX

It will use the Google Tag Manager

Comments šŸ’¬


If you have a Disqus account, you can show a comments section below each post.

To enable Disqus comments, add your Disqus shortname to your project's _config.yml file:

  disqus_shortname: my_disqus_shortname


Cusdis is an open-source alternative to Disqus. You can read more about it in the documentation

To enable it, set your Cusdis name in _config.yml:

  cusdis_app_id: my_data-app-id                                     


Utterances is another open source alternative linked to one's GitHub account. It stores the comments as GitHub issues on a repository for each page.

Install the utterance app to your repo. After installing, add your info in the _config.yml:

  utterances:              # Enable by filling below information. For more info, go to https://utteranc.es
    repo:                  # your public comments repository (e.g. owner/repo)
    issue-term:            # Issue term (e.g. "comment" consider issues with this word in the title as comments)
    theme:                 # OPTIONAL: Take the `color_theme` by default, or set a custom one like github-dark-orange
    label:                 # OPTIONAL: Adds an issue label in the issue

Math typesetting with KateX

When KateX is set in _config.yml:

katex: true # to enable it

You can then wrap math expressions with $$ signs in your posts and make sure you have set the katex variable in _config.yml to true for math typesetting.

For inline math typesetting, type your math expression on the same line as your content. For example:

Type math within a sentence $$2x^2 + x + c$$ to display inline

For display math typesetting, type your math expression on a new line. For example:

  \bar{y} = {1 \over n} \sum_{i = 1}^{n}y_i

You can find a cheat sheet of the compatible LaTex symbols online.

Diagrams with Mermaid

Enable the mermaid-js diagram rendering by setting mermaid to true in the _config.yml. This will load and init the mermaid.min.js.

mermaid: default # Enable mermaid-js for diagrams, use theme: base, forest, dark, default, neutral

Find all the help you need on the official mermaid documentation. Use mermaid as color highlighter language to render the diagram or with the class="mermaid" inside the <div>:

    Alice->>John: Hello John, how are you?
    John-->>Alice: Great!

Social icons

In _data/social.yml you can customize the social icons that will be displayed in the post to share your post. You can also enable RSS. The site icons come from Font Awesome.

In _data/icons.yml you can set the footer icon that will appear at the bottom of the page. They will redirect the user on your profile on to other platforms like Twitter, GitHub and so many more!

You can add a cookie consent with a disclaimer if you use Google Analytics while respecting the GDPR. Set to true, there will be a banner at the bottom of the page with the disclaimer, and an approve button. Once the user clicks on "Approve" the cookies will be created for Google Analytics.

Share in article

The share icons are the one at the bottom of the blog page if enabled. They will on click redirect you to the logo's platform to share the article.

Display icons in the footer. All icon variables should be your username enclosed in quotes (e.g. "username") in _data/icons.yml.

You can update the RSS settings in _data/social to change the default feed path (generated by jekyll-feel). To enable the share icons at the bottom of each article set to true the one you'd like under share in the _data/social.yml file.

Personalize your Blog Posts šŸ“

When writing a post, be sure in jekyll to:

  • Put it in the _posts folder
  • Name it with the date first like 2019-08-21-This-is-my-blog-post.md

Please refer to the Jekyll docs for writing posts.

Layout: Post

These are the basic features you can use with the post layout, in the comment the Opt means that it is optional.

layout: post
title: Hello World                                # Title of the page
hide_title: true                                  # [Opt] Hide the title when displaying the post, but shown in lists of posts
feature-img: "assets/img/sample.png"              # [Opt] Add a feature-image to the post
thumbnail: "assets/img/thumbnails/sample-th.png"  # [Opt] Add a thumbnail image on blog view
color: rgb(80,140,22)                             # [Opt] Add the specified colour as feature image, and change link colors in post
position: 1                                       # [Opt] Set position on the menu navigation bar
tags: [sample, markdown, html]                    # [Opt] Add tags to the page

With thumbnail, you can add a smaller image than the feature-img. If you don't have a thumbnail, you can still use the same image as the feature one. Or use the gulp task to create it.

If you don't use a feature image, but color, the transparent background is set comes from lineart.png. You can edit it in the config file (_config.yml > color_image). If you want another one, put it in /assets/img as well.

For position, if not set on all pages, it will be by alphabetical order without position then by position order. If two pages have the same position number, the order is decided by alphabetical order on the page title.

There's also bootstrap: true which is not mandatory and only useful if you want to add HTML content in your page that requires bootstrap. It will respect the page and theme layout, mind the padding on the sides.

Post excerpt

The excerpt are the first lines of an article that is displayed on the blog page. The length of the excerpt has a default of around 250 characters or can be manually set in the post using:

in conflig.yml:

excerpt: true

Then in your post, add the excerpt separator:

layout: post
title: Sample Page
excerpt_separator: <!--more-->

some text in the excerpt
... rest of the text not shown in the excerpt ...

The html is stripped out of the excerpt, so it only displays text.

Image aligner

To easily add align images side by side in your article using the aligner.html include:

{% include aligner.html images="path/to/img1.png,path/to/img2.png,path/to/img3.png" column=3 %}

Use it in any markdown file. There are two fields in the include you need to look into:

  • images: Takes a string separated with , of all the images' path.
    • It by default look into assets/img/ so give the path from there.
  • column: (OPTIONAL) Set the number of column you want your imaged displayed in.
    • default is 2 columns
    • column=3 set 3 columns
    • column="auto" makes as many columns as images

Code highlight

Like all CSS variables in the theme, you can edit the color of the code highlight in _sass > base > _variables.scss. The code highlighting works with base16 you can find existing example of your favourite highlight color scheme on this format.

Feature pages and layouts

All feature pages besides the "home" one are stored in the page folder, they will appear in the navigation bar unless you set Hide: true in the front matter.

Here are the documentation for the other feature pages that can be added through _config.yml.

Non-standard features are documented below.

Layout: Default

This layout includes the head, navigation bar and footer around your content. Unless you are making a custom layout you won't need it.

Layout: Home šŸ”

This page is used as the home page of the template (in the index.html). It displays the list of articles in _posts. You can use this layout in another page (adding a title to it will make it appear in the navigation bar).

The recommended width and height for the home picture is width:2484px; and height:1280px which are the dimensions of the actual picture for it to be rolling down as you scroll the page.

If your posts are not displaying ensure that you have added the line paginate: 5 to _config.yml.

Layout: Page šŸ“„

The page layout has a bit more features explained here.

layout: page
title: "About" 
subtitle: "This is a subtitle"   
feature-img: "assets/img/sample.png" 
permalink: /about/                   # Set a permalink your your page
hide: true                           # Prevent the page title to appear in the navbar
icon: "fa-search"                    # Will Display only the fontawesome icon (here: fa-search) and not the title
tags: [sample, markdown, html]

The hide only hides your page from the navigation bar, it is, however, still generated and can be accessed through its link.

Feature: Portfolio šŸ—‚

Portfolio is a feature page that will take all the markdown/html files in the _portfolio folder to create a 3-columns image portfolio matrix.

To use the portfolio, simply create a portfolio.md with this information inside:

layout: page
title : Portfolio 

{% include default/portfolio.html %}

Portfolio posts

You can format the portfolio posts in the _portfolio folder using the post layout. Here is a little explanation on some of the possible features you can use.

If you decide to use a date, please be sure to use one that can be parsed such as yyyy-mm-dd. You can see more format examples in the demo posts that are available for the theme:

layout: post
title: Circus                       # Title of the portfolio post
feature-img: "assets/img/portfolio/cake.png"   # Will display the image in the post
img: "assets/img/portfolio/cake.png"           # Will display the image in the portfolio page
date: 2019-07-25                    # Not mandatory, however needs to be in date format to display the date

Portfolio in gem

Make sure your _config.yml contains the following if you are using the theme as a gem:

    output: true
    permalink: /:collection/:name

This creates the collection for Jekyll, so it can find and display your portfolio posts.

You can create a gallery using Masonry JS which will placing the pictures at the optimal position based on available vertical space. You need to specify the gallery_path which will be used to find the pictures to render. It will take all the pictures under that directory. Then use the include to add it in your page.

layout: page
title: Gallery
gallery: "assets/img/pexels"

{% include default/gallery.html gallery_path=page.gallery %}

Feature: Search šŸ”

The search feature is based on Simple-Jekyll-search there is a search.liquid file that will create a list of all the site posts, pages and portfolios. Then there's a script displaying the formatted results in the search page.

To exclude contents from the search add the exclude: true option in the markdown header. By default, all posts, pages, and collections are available in the search. Hide the search page from the navigation bar with the hide: true option. You can remove the icon by removing icon:

layout: search
title: Search
icon: "search"

Feature: Tags šŸ·

Tags should be placed between [] in your post metadata. Separate each tag with a comma. Tags are recommended for posts and portfolio items.

For example:

layout: post
title: Markdown and HTML
tags: [sample, markdown, html]

Tags are case-sensitive Tag_nAme ā‰  tag_name

All the tags will be listed on the "tags" page with a link toward the pages or posts. The Tag page can be hidden with the hide option. You can remove the icon by removing icon (like for the search page).


Liquid tags

Jekyll works with liquid tags usually represented by:

{{ liquid.tag | filter }}

These are useful to render your jekyll files. You can learn more about them on shopify's doc

Gulp toolbox


Before you need to have node and npm installed:

  • Windows: https://nodejs.org/
  • Ubuntu/Debian: apt-get install nodejs npm libgl1 libxi6
  • Fedora (dnf) / RHEL/CentOS (yum): dnf install node npm libglvnd-glx libXi

Then you need to install gulp-cli and its dependencies:

cd assets/
sudo npm install gulp-cli -g
npm install

Minimizing and optimizing: css, js and images

You can run the default task that will compress the js, css and images and create the thumbnails for the supported image formats:

cd assets/
gulp default
gulp thumbnails-all # to create all of the images thumbnails
gulp thumbnails     # to create thumbnails for the feature-img/ only
# tip: run a git status to see the changes
git status

You can find more about the gulp tasks in the gulpfile.js.

Create a post

To create a .md file in the _posts/ section with the jekyll format of today's date. Use this command with the title you'd like to create the very basic post.

gulp post -n 'title of the post'

A file will be created following the format yyyy-mm-dd-title-of-the-post.md with default post attributes inside. Nothing will happen if the file exists already.

Use as Ruby Gem šŸ’Ž

You can use Type-on-strap as a gem.

Using the Ruby Gem Method. Add this line to your Jekyll site's Gemfile (or create one):

gem "type-on-strap"

Add this line to your Jekyll site's _config.yml file:

theme: type-on-strap

Then run Bundler to install the theme gem and dependencies:

bundle install

Then you can start adding content like:

  • Add a index.html file
  • Add the feature page you want. (ex: as it is already in pages)
  • Add posts in _posts and _portfolio to be displayed

Remote Theme

Now you can use any theme gem with GitHub pages with 29/11/2017 GitHub Pages Broadcast. For that remove all theme: attributes from _config.yml and add instead:

remote_theme: sylhare/Type-on-Strap
