  22. Twitter Bootstrap Makes Our Site Look Good

  • We'll cover the importance and benefit of using a CSS and JS framework like Bootstrap.
  • A best practice for adding Bootstrap to Rails is by adding a gem to our app.
  • Adding it this way will ensure it is added to our site optimally, in terms of speed and functionality.

###Gemfile

...
# Use Twitter Bootstrap library for front-end UI and layout
gem 'bootstrap-sass', '3.3.7'
...

We renamed our application.css file to application.css.scss

###app/assets/stylesheets/application.css.scss

@import 'bootstrap-sprockets';
@import 'bootstrap';

###app/views/layouts/application.html.erb

<div class="container">
  <%= yield %>
</div>
