CSS3 has been in the works for a while now. The current implementation of CSS (2.1) includes browser rendering inconsistencies but does provide excellent positioning and formatting properties. CSS3 promises to expand positioning and column layout capabilities, allow layered backgrounds with quicker load times, and real opacity of design items to name a few.
