"""
The ‘perspective-origin’ property establishes the origin for the perspective property. It effectively sets the X and Y position at which the viewer appears to be looking at the children of the element.

. . .

Value:	 [ [ <percentage> | <length> | left | center | right ] [ <percentage> | <length> | top | center | bottom ]? ] | [ [ left | center | right ] || [ top | center | bottom ] ]

This allows syntax like "perspective-origin: 10px", but doesn't say what it means.  Looking at implementations, it should be the same as "10px center", just like transform-origin.  This needs to be specified explicitly.
Comment 1 Simon Fraser 2012-02-21 22:25:44 UTC 
perspective-origin syntax should match transform-origin, and be like background-position.
Comment 2 Simon Fraser 2012-02-29 17:00:22 UTC 
Forward-duping this to 16064.
