Jekyll support for spoilers

Add one of these lines to your Gemfile:

# always use the latest version
gem 'jekyll-spoiler'

# use pessimistic lock
gem 'jekyll-spoiler', '~> 1.0'

# fetch gem from git
gem 'jekyll-spoiler', git: 'https://github.com/Strappazzon/jekyll-spoiler.git', tag: '1.0.0'

Then execute bundle install to install the Gem.

1. Use the Liquid filter and/or tag in your website

   • Use this to add spoiler text:

     {{ "Lorem ipsum dolor sit amet." | spoiler }}

   • Use this to add collapsible spoiler text:

     {% spoiler %}
       Lorem ipsum dolor sit amet, consectetur adipiscing elit.
       Ut enim ad minim veniam, quis nostrud exercitation ullamco.
     {% endspoiler %}
     
     {% spoiler title="Spoilers Ahead!" %}
       Lorem ipsum dolor sit amet, consectetur adipiscing elit.
       Ut enim ad minim veniam, quis nostrud exercitation ullamco.
     {% endspoiler %}

2. Style the spoiler using CSS.
   An example can be found here: docs/_sass/_spoiler.scss.
