Variables
Variables determine the number of columns, the gutter width, and the media query point at which to begin floating columns. We use these to generate the predefined grid classes documented above, as well as for the custom mixins listed below.

+While Bootstrap is built on Less, it also has an official Sass port. We maintain it in a separate GitHub repository and handle updates with a conversion script.
+ +What's included
+Since the Sass port has a separate repo and serves a slightly different audience, the contents of the project differ greatly from the main Bootstrap project. This ensures the Sass port is as compatible with as many Sass-based systems as possible.

+ + +Installation
+Use the appropriate guide for your environment of choice.
+ +Rails
+ +bootstrap-sass is easy to drop into Rails with the asset pipeline.
In your Gemfile you need to add the bootstrap-sass gem, and ensure that the sass-rails gem is present—it is added to new Rails applications by default.
bundle install and restart your server to make the files available through the pipeline.
Compass without Rails
+ +Install the gem:
+ +{% highlight bash %} +gem install bootstrap-sass +{% endhighlight %} + +If you have an existing Compass project:
+ +{% highlight ruby %} +# config.rb: +require 'bootstrap-sass' +{% endhighlight %} + +{% highlight bash %} +bundle exec compass install bootstrap +{% endhighlight %} + +If you are creating a new Compass project, you can generate it with bootstrap-sass support:
This will create a new Compass project with the following files in it:
+ +-
+
- _variables.scss — all of bootstrap variables (override them here). + +
- styles.scss — main project SCSS file, import `variables` and `bootstrap`. +
Sass-only without Compass or Rails
+ +Require the gem, and load paths and Sass helpers will be configured automatically:
+ +{% highlight ruby %} +require 'bootstrap-sass' +{% endhighlight %} + +Using bootstrap-sass as a Bower package is still being tested. You can install it with:
+ +{% highlight bash %} +bower install 'git://github.com/twbs/bootstrap-sass.git#v3.0.3.0' +{% endhighlight %} + +JS and fonts
+ +If you are using Rails or Sprockets, see Usage. If none of Rails/Sprockets/Compass were detected the fonts will be referenced as:
+ +{% highlight sass %} +"#{$icon-font-path}/#{$icon-font-name}.eot" +{% endhighlight %} + +$icon-font-path defaults to bootstrap/. When not using an asset pipeline, you have to copy fonts and javascripts from the gem.
In ruby you can get the assets' location in the filesystem like this:
+ +{% highlight ruby %} +Bootstrap.stylesheets_path +Bootstrap.fonts_path +Bootstrap.javascripts_path +{% endhighlight %} + + +Usage
+ +Sass
+ +Import Bootstrap into a Sass file (for example, application.css.scss) to get all of Bootstrap's styles, mixins and variables! We recommend against using //= require directives, since none of your other stylesheets will be able to access the Bootstrap mixins or variables.
You can also include optional Bootstrap theme:
+ +{% highlight sass %} +@import "bootstrap/theme"; +{% endhighlight %} + +The full list of Bootstrap variables can be found in the Customizer. You can override these by simply redefining the variable before the @import directive, e.g.:
You can also import components explicitly. To start with a full list of modules copy this file from the gem:
+ +{% highlight bash %} +cp $(bundle show bootstrap-sass)/vendor/assets/stylesheets/bootstrap/bootstrap.scss \ + app/assets/stylesheets/bootstrap-custom.scss +{% endhighlight %} + +In your application.sass, replace @import 'bootstrap' with:
Comment out any modules you don't need from bootstrap-custom.
JavaScript
+ +We have a helper that includes all Bootstrap javascripts. If you use Rails (or Sprockets separately), put this in your Javascript manifest (usually in application.js) to load the files in the [correct order](/vendor/assets/javascripts/bootstrap.js):
You can also load individual modules, provided you also require any dependencies. You can check dependencies in the [Bootstrap JS documentation][jsdocs].
