bourbon

A simple and lightweight mixin library for Sass.

Bourbon is a library of pure Sass mixins that are designed to be simple and easy to use. No configuration required. The mixins aim to be as vanilla as possible, meaning they should be as close to the original CSS syntax as possible.

The mixins contain vendor specific prefixes for all CSS3 properties for support amongst modern browsers. The prefixes also ensure graceful degradation for older browsers that support only CSS3 prefixed properties. Bourbon uses SCSS syntax.

Requirements

• Sass 3.4+ or LibSass 3.1+

Installation

For command line help, visit our wiki page on Bourbon’s command line interface.

1. Install the Bourbon gem using the RubyGems package manager:

gem install bourbon

Alternatively, you can install Bourbon with Bower.

1. Install the Bourbon library into the current directory:

bourbon install

Pro Tip: You can target installation into a specific directory using the path flag:

bourbon install --path my/custom/path/

1. Import Bourbon at the beginning of your stylesheet:

@import "bourbon/bourbon";

It’s not recommended to add or modify the Bourbon files so that you can update them easily.

Installation for Ruby on Rails 3.1+

1. Add Bourbon to your Gemfile:

gem 'bourbon'

1. Then run:

bundle install

1. Restart your server and rename application.css to application.scss:

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

1. Delete all Sprockets directives in application.scss (require, require_tree and require_self) and use Sass’s native @import instead.

2. Import Bourbon at the beginning of application.scss. All additional stylesheets should be imported below Bourbon:

@import "bourbon";
@import "home";
@import "users";

Help! I’m getting an undefined mixin error.

1. Uninstall any Bourbon gem versions you already have:

gem uninstall bourbon

1. Reinstall the Bourbon gem, using the -v flag to specify the version you need:
