If you want a lightweight set of mixins for your next project, then the Bourbon mixin library, from Thoughtbot, is a great choice. It provides a comprehensive set of mixins, functions and add-ons that are simple to implement and well documented.
Working in a Rails project using Bourbon is as simple as installing the gem and making some minor adjustments to the application.css file, however, outside Rails there is a little bit more work to do.
