ISSUE-41: Extend 'box-shadow' to specify the "spread" of the shadow

shadow spread

Extend 'box-shadow' to specify the "spread" of the shadow

State:

CLOSED

Product:

CSS3 Backgrounds and Borders

Raised by:

Bert Bos

Opened on:

2008-05-12

Description:

Eli Morris-Heft summarized in http://lists.w3.org/Archives/Public/www-style/2008May/0094.html some ideas (from Brad Kemper and others) for extending 'box-shadow' (and 'text-shadow'?):

1) An optional fourth <length> value can make the shadow larger (or smaller), as if the shadow was cast not by the box itself, but by a box that is that much bigger on all sides. This is the "spread." (Such a spread seems most useful to increase the effect of a "glow," less so for a shadow.)

An image http://www.doublefishstudios.com/~dai/boxes.png shows the intended effects.
