title: Framework for CSS in Rails 3.1
body: <p>Which framework do you use in Rails 3.1?</p>
  
  <p>I basically want to have a standard set of mixins like gradient and rounded corner etc, but maybe there are other advantages of certain frameworks that I am not aware of.</p>
  
  <p>Can you please recommend a framework to use with Rails 3.1 to cover most of what I will need to simplify and standardize my stylesheet development</p>
