remote_theme: coogie/oscailte

Install via Gemfile

  1. Add this line to your Jekyll site's Gemfile:
gem "oscailte"
  1. And add this line to your Jekyll site's _config.yml:
theme: oscailte
  1. And then execute:
$ bundle
  1. Or install it yourself as:
$ gem install oscailte

Enabling Comments (via Disqus)

Optionally, if you have a Disqus account, you can tell Jekyll to use it to show a comments section below each post.

To enable it, add the following lines to your Jekyll site:

  shortname: my_disqus_shortname

You can find out more about Disqus' shortnames here.

Comments are enabled by default and will only appear in production, i.e., JEKYLL_ENV=production

If you don't want to display comments for a particular post you can disable them by adding comments: false to that post's YAML Front Matter.

:warning: url, e.g. https://example.com, must be set in you config file for Disqus to work.

Social Networks

You can add links to the accounts you have on other sites, with respective icon, by adding one or more of the following options in your config. These usernames are nested under oscailte.social, with the keys being simply the social network's name:

    twitter: jekyllrb
    github: jekyll
    dribbble: jekyll
    facebook: jekyll
    flickr: jekyll
    instagram: jekyll
    linkedin: jekyll
    pinterest: jekyll
    telegram: jekyll
    keybase: jekyll
    rss: rss

Enabling Google Analytics

To enable Google Analytics, add the following lines to your _config.yml:

  google_analytics: UA-NNNNNNNN-N

Google Analytics will only appear in production, i.e., JEKYLL_ENV=production Oscailte will also inform Google Analytics of your user's request for DNT.

Enabling Excerpts on the Home Page

To display post-excerpts on the Home Page, simply add the following to your _config.yml:

show_excerpts: true

Customising Oscailte

Site Colours

Oscailte makes extensive use of CSS Custom Properties for various parts of its look and feel. A full list of the properties used throughout can be found in /_sass/_oscailte.scss. Some of these properties are generated via SCSS (such as typography), but are still Custom Properties in-browser (not Sass variables).
