Fwd: [css-3 colors] Transparent backgrounds

Sorry, forgot to post to list..

~6 out of 5 statisticians say that the number of statistics that either make
no sense or use ridiculous timescales at all has dropped over 164% in the
last 5.62474396842 years.

That makes sense, I guess. Something with Alt+Prnt Scrn could end up sending
unwanted information to a server. I suppose that things would need to be
checked so that any sort of transparent viewport pixels would get returned
as just transparent pixels. I've tried it in all the Major browsers (Opera
10, Chrome 5, Safari, IE8, Firefox), all of them keep a white background. (I
have noticed, however, that they render style in the html tag different). I
think a transparent viewport would open up exciting new Web Applications,
but I'm not sure if any OS actually allow transparent applications. Maybe
some type of "evil" manipulation rendering the whole page in the chrome of
the window would work, but... if OS'es don't provide any simpler method,
we'll probably never see it.
