I have downloaded Twitter Bootstrap from http://getbootstrap.com/customize/
and now I would change some proprieties such as @body-bg or @navbar-default-bg. Before Bootstrap, I used Zurb Foundation and I changed "foundation_and_override.sass" file. Is there something similar for Bootstrap?
My project is on Ruby on Rails
Check out this similar question. It shouldn't matter which exact file you put it in.. all the css will get compiled in your assets directory in rails.
You can use this bootstrap gem in Rails, it's well maintained and up to date. The variables are defined here, so you know which value to set before your @import 'twitter/bootstrap' statement as shown in the Readme.
I'm using this exact same approach and am quite happy with it.
