I am using bootstrap sass:
https://github.com/twbs/bootstrap-sass
but where is the boostrap-responsive.css file? I'm trying to add the classes row-fluid to make a layout as shown in this link, but no classes are being picked up.

As there is no bootstrap-responsive.css within Bootstrap 3.x, the .css is separated for each of the elements within the /assets/stylesheets/bootstrap folder, called and imported by the _bootstrap.scss.
