CSS has been undergoing a quiet renaissance lately. Lots of big features which previously required an external tool to use, are now native parts of the language, and its growing more and more all the time. If you haven't used CSS in a long time, for whatever reason, now is the time to take a look again.
Finally there’s a way to have gradients that don’t look like shit.
Defining them to interpolate in a suitable color space instead of the completely inappropriate sRGB is great!
