less-rails-bootstrap

If you're using Sass with Bootstrap, then you're probably using the compiled version of Bootstrap (i.e. the final .css file.) If that's the case, you're missing out all the LESS mixins and variables that Bootstrap provides. If you're serious about adopting Bootstrap, you should consider switching to LESS. The less-rails-boostrap gem makes it easy if you're working on a Rails app. It integrates seamlessy with Rails' asset pipeline, and has a generator for Rails scaffold CSS. https://github.com/metaskills/less-rails https://github.com/metaskills/less-rails-bootstrap
