Title: CSS manual optimization

Leading zeros, repeated values, shorter declarations, unneeded "px". Managed to cut off ~2kBs of size, and since this is manual not all declarations are caught.

Also, there's quite a lot of !important declarations, different kinds of colors, and vendor prefixes. How low is the browser support you're aiming for?
