How do you customize something like Twitter Bootstrap in a Rails 3.2 app? I have the gem ('bootstrap-sass 3.0.3.0') already. Do I just get a copy of the Sass files and not use the gem at all? I feel like I am missing something here because I have begun to put !important in the CSS of my code. (I'm just trying to change the color of the navbar into a gradient.)
Is there also a way to not use the entire framework? I feel like I don't use some of the components anyway (both CSS and JS).
