Bourbon Sass Mixin Library

A simple and lightweight mixin library for Sass

Bourbon is a comprehensive library of 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.

#Documentation & Demo


Sass 3.2+

Install for Rails 3.1+

In your Gemfile:

gem 'bourbon'

Then run:

$ bundle install

Restart your server. Then rename application.css to application.css.scss:

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

Delete the sprocket directive in application.css.scss: Why?

*= require_tree .

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

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

Help! I'm getting an undefined mixin error.

Rails 3.0.x Install Instructions | Rails 2.3 Install Instructions

Non-Rails projects

Bourbon includes an easy way to generate a directory with all the necessary files.
For command line help: $ bourbon help or visit the Command line tools wiki

####Install (Bourbon v3.0+)

gem install bourbon

Install Bourbon into the current directory by generating the bourbon folder:

bourbon install

The generated folder will contain all the mixins and other necessary Bourbon files. It is recommended not to add or modify the Bourbon files so that you can update Bourbon easily.


Lastly, import the mixins at the beginning of your stylesheet(s):

@import 'bourbon/bourbon';

Note: Bourbon no longer requires a custom sass --watch command for Bourbon v3.0+
