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-st...@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,
