During the design phase of this blog, I have not only written a cross-browser implementation of border-image, but I’ve also added support of hsl colors to jQuery’s animate function.
citizenColor is not a traditionnal jQuery plugin, it’s more some kind of hack, but it does what it is intended for. It overwrites native jQuery’s animate function and allows you to use hsl colors such as hsl(272, 40%, 70%). But it also allows relative animations, like the ones you can use with dimensions in jQuery: hsl(+=54, +=20%, -=10%)
The only limitation is that you can’t use it on elements with different colors.
