Some nice code there. Have you thought about using less to make the css more readable?
For instance, I use a mixin called border-radius, which is replaced by all the vendor-specifics.

Just @include "bootstrap.less" at the top of your less file, add your rules below and compile just your less file using lessc. Easy.
