HSL Color Specification and CSS3

By Deane Barker on July 2, 2003

A (CSS) Horse of a Different Color: The W3C is busy working on the CSS3 specification. This article has information on an interesting twist to colors: specifying them in HSL (Hue, Saturation, Lightness) instead of the traditional RGB (Red, Green, Blue).

I tooled around the What’s New page at the W3C for a while trying to figure out where they were going with CSS3, and as near as I can tell, all the changes seem to be related to internationalization: things like text direction (right-to-left, vertical, etc.), unicode support, support for “Ruby” which is an annotation style used in Asian languages, etc. They’re building things in a “module” format this time — releasing small improvements one at a time instead of turning over the whole shebang at once.
