Comment #2 on issue 1783 by [email protected]: support css @keyframes
http://code.google.com/p/google-caja/issues/detail?id=1783
Controlling spec seems to be http://dev.w3.org/csswg/css-animations/
This CSS module describes a way for authors to animate the values of CSS
properties over time, using
keyframes. The behavior of these keyframe animations can be controlled by
specifying their duration,
number of repeats, and repeating behavior.

Re parsing this stuff,
The following is the grammar for the keyframes rule.
keyframes_rule: KEYFRAMES_SYM S+ IDENT S* '{' S* keyframes_blocks '}' S*;
keyframes_blocks: [ keyframe_selector '{' S* declaration? [ ';' S*
declaration? ]* '}' S* ]* ;
keyframe_selector: [ FROM_SYM | TO_SYM | PERCENTAGE ] S* [ ',' S* [
FROM_SYM | TO_SYM | PERCENTAGE ] S* ]*;
@{K}{E}{Y}{F}{R}{A}{M}{E}{S} {return KEYFRAMES_SYM;}
{F}{R}{O}{M} {return FROM_SYM;}
{T}{O} {return TO_SYM;}
so within @keyframes "from { ... }" is not a set of property declarations
for a selector that matches <from> elements.
Our parser needs to recognize
from { ... }
to { ... }
<percentage> { ... }
as blocks that can themselves contain @rule blocks and selector rule blocks.
