Description Dave Tharp 2012-04-04 13:54:11 PDT
No red should be visible on the rendered page.
Comment 1 Dave Tharp 2012-04-04 15:12:57 PDT
Here's the crux of the problem:  The CSS in the test htm file specifies
the box-shadow thusly:

    box-shadow: 50px 10px 0px 10px ;

The important thing to note here is that there is no shadow color
specified.  IE, Mozilla, and Opera default the shadow color to black.
WebKit defaults the color to transparent.

Unfortunately, the spec ( http://www.w3.org/TR/css3-background/#the-box-shadow ) does not seem to specify the behavior when no color is given.  It does show that color is indeed optional.

It seems that IE, Mozilla, and Opera have all interpreted a lack of specified color to mean "default to black". And this actually makes sense to me.  I mean, why would you specify a shadow if it wasn't going to be visible anyway?

Note the same root issue is the cause of bug 83223.
