Bootstrap for Rails
bootstrap-sass is an SASS-powered version of Twitter's Bootstrap, ready to drop right into your asset-pipeline powered Rails applications.
In your gemfile:
gem 'bootstrap-sass', '1.3.0'
In your CSS file of choice:
@import "bootstrap"; /* Use this to get all of Bootstrap's @mixins and $variables */
/* *= require bootstrap // This doesn't (at the moment) preserve loaded @mixins, * //so I wouldn't use this. Stil, its an alternative. */
