:warning: Bourbon **4.0.0** requires Sass **3.3.x**. If you are using **libsass** or **sass-rails** use **3.2.0**.
## A 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.
### [Documentation & Demo](http://bourbon.io)
### Requirements
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?](https://github.com/thoughtbot/bourbon/wiki/Rails-Sprockets)
*= 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";

### 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](https://github.com/thoughtbot/bourbon/wiki/Command-Line-Tools)
##### 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.
You can specify a target directory using the `path` flag:
bourbon install --path my/custom/path/
##### Import
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+
##### Other Commands
Visit the [Command line tools wiki](https://github.com/thoughtbot/bourbon/wiki/Command-Line-Tools) for a complete list
