I've never seen anyone try to do this before. It might very
well be possible and does seem logical. Could you try a couple of
experiments to help narrow down the problem?
1) Change the syntax:
2) Move the embed to the <mx:Application> root tag,
removing it from the CSS file.
3) Create a Canvas in your app and code the Embed right in
the HTML. If that works, move it to the CSS file.
I'm wondering if the issue is with the Application or the
Embed syntax or the combination.
I think the problem is that my swf is not recognizing the
stage size. I did a quick test with another mc in the swf (still
using the css, but with a different mc name after the #), and it
appeared and stretched. I will do some additional testing to see
where the breakdown occurs and will post back.
One other thing I'm having problem with is flex builder
(Version: 2.0.167022) telling me "CSS Value for 'backgroundSize'
not supported." Even though it's documented this way and the
StyleExplorer creates this syntax...
here is the syntax of my style (the first post had quotes
around the 100%):
