Three drafts of CSS modules have been updated today:

  - "CSS3 module: backgrounds"[1]
  - "CSS3 module: color"[2]
  - "CSS3 module: cascading and inheritance"[3]

The most salient changes are the following:

The Backgrounds module proposes some new properties for stretching the
background, more control over tiling, and the possibility to leave the
background of the border transparent.

The Color module adds the 140 or so colors that Mosaic inherited from
the X Window Sytem, Netscape from Mosaic, and all browsers since then
from Netscape. Most browsers, except those on very small devices,
already support them. The system colors are expanded and regularized a
bit. The draft also adds color profiles for embedded images, although
they are not really new: SVG already has them.

The Color module also proposes full control over transparency of
anything that has color, by means of RGBA colors (colors with an
"alpha channel") as well as with an 'opacity' property (from SVG
again), to make a whole element semi-transparent at once.

The Cascading module is mostly a rewrite of CSS2. The only new thing
is the reduced influence of the old HTML presentational attributes

As always, the CSS working group is hoping for feedback and
