[whatwg] [CSSWG][css-cascade-3] Last Call WD for CSS3 Cascade

[fantasai]

The CSS WG has published a Last Call Working Draft of the
CSS Cascading and Inheritance Module Level 3:

     http://www.w3.org/TR/css-cascade-3/

This CSS module describes how to collate style rules and assign
values to all properties on all elements by way of cascading
(choosing a winning declaration among many) and inheritance
(propagating values from parent to child).

Notable additions since CSS2.1 include

   * cascading rules for scoped declarations
     http://www.w3.org/TR/css-cascade-3/#cascade-scope

   * full cascade list including transitions, animations, and DOM
     override rules
     http://www.w3.org/TR/css-cascade-3/#cascade-origin

   * the 'all' shorthand to reset all CSS properties
     http://www.w3.org/TR/css-cascade-3/#all-shorthand

   * the 'initial' and 'unset' keywords to restore initial state
     http://www.w3.org/TR/css-cascade-3/#initial
     http://www.w3.org/TR/css-cascade-3/#unset

Significant changes since the last WD are listed at:
   http://www.w3.org/TR/2013/WD-css-cascade-3-20130730/#changes
and include changes to the 'all' shorthand to exclude bidi controls
   http://www.w3.org/TR/2013/WD-css-cascade-3-20130730/#all-shorthand
and the replacement of the 'default' keyword with 'unset'
(with different semantics):
   http://www.w3.org/TR/2013/WD-css-cascade-3-20130730/#inherit-initial
(The draft also received a reorg/editorial overhaul.)

Please send any comments to the www-style mailing list [1],
<www-style at w3.org>, and  please, prefix the subject line with

     [css-cascade-3]

(as I did on this message). The deadline for comments is

   ** 26 August 2013 **

Please let us know if you need an extension.

We would particularly appreciate review of this module from the
HTML and WebAPI communities. Thanks!

For the CSS WG,
