Gem Version

'font-awesome-sass' is a Sass-powered version of FontAwesome for your Ruby projects and plays nicely with Ruby on Rails, Compass, Sprockets, etc.

Refactored to support more Ruby environments with code and documentation humbly used from the excellent bootstrap-sass project by the Bootstrap team

Breaking Changes

With the update to Font Awesome 5.x there are some breaking changes that will effect your use of this gem. Some of the changes include:

  • Icon name changes
  • New icons
  • The use of an icon style (solid, regular, or brands)

You can find more detailed information on these changes on our Getting Started guide, our How to Use guide, and our Upgrading from Version 4 guide.


Please see the appropriate guide for your environment of choice:

a. Ruby on Rails

In your Gemfile include:

gem 'font-awesome-sass', '~> 5.15.1'

And then execute:

bundle install

Import the FontAwesome styles in your app/assets/stylesheets/application.css.scss. The font-awesome-sprockets file includes the sprockets assets helper Sass functions used for finding the proper path to the font file.

@import "font-awesome-sprockets";
@import "font-awesome";

If app/assets/stylesheets/application.css.scss does not exist then rename app/assets/stylesheets/application.css and add the @import statements below the *= require statements but outside of the comment block.

Rails Helper usage

With Font Awesome 5.x you now need to select what style of icon you want to use. Font Awesome 5.x has 3 styles:

  • solid (fas)
  • regular (far)
  • brands (fab)

In your view:

icon('fas', 'flag')
# => <i class="fas fa-flag"></i>
icon('far', 'address-book', class: 'strong')
# => <i class="far fa-address-book strong"></i>
icon('fab', 'font-awesome', 'Font Awesome', id: 'my-icon', class: 'strong')
# => <i id="my-icon" class="fab fa-font-awesome strong"></i> Font Awesome

Note: the icon helper can take a hash of options that will be passed to the content_tag helper

b. Compass without Rails

Install the gem

gem install font-awesome-sass

If you have an existing Compass project:

# config.rb:
require 'font-awesome-sass'

Import the FontAwesome styles

@import "font-awesome-compass";
@import "font-awesome";

Upgrading from FontAwesome::Sass 4.x

Prepend the style of the icon you want to use (fas, far, fab) class to existing icons:

4.x Syntax

<i class="fa fa-github"></i>

5.x Syntax (GitHub icon exists in the Brands style)

<i class="fab fa-github"></i>
