Is it possible to have a transparent background?

Question

I'd like to have the users desktop or whatever windows they have open show through the background with a slight bit of opacity. I did a quick mockup in photoshop to try and illustrate what I'm aiming for

I'm fine with using a bit of jQuery if need be, but would prefer to keep the foot print light. I don't really want to add a ton of overhead just for a fancy effect.

Answer 1

No. You cannot make the browser window translucent.

Answer 2

This is completely impossible... using current APIs. It's theoretically possible that one might be implemented in the future, but for now, the best you can do is transparency to the user desired color.
