fadeyev, your first example is a little misleading. Only Safari 3-4 required the border-radius syntax to be declared individually. So really this is how it goes: /* these two lines for saf 3-4 support */ -webkit-border-top-left-radius: 5px; -webkit-border-top-right-radius: 5px; /* all you need for Saf5, Chrome, Op, FF1+, IE9 */ -moz-border-radius: 5px 5px 0 0; border-radius: 5px 5px 0 0; That said, I like the project. Just clarifying this. :) EDIT: given the spec'd shorthand syntax, your shorthand for unique corners seems to conflict `(5px, 0, 0, 5px)`. I'd suggest changing that.
