The main thing I like about this library is that it solves all my CSS issues of not being able to use any other styles besides webkit-specific ones (because as soon as i add anything else - even just some basic font settings or something simple - they go out).
This means no more IE8 & 9 compatibility problems! And with its new way to write custom selectors makes me so happy because now there isn't such an issue anymore when using different frameworks/designs which don't have support in certain browsers yet either :D.
