[jQuery] Lightbox overlay, fade out background

[jQuery] Lightbox overlay, fade out background


Hey guys, I have been looking at some code of lighboxes and am trying
to fade out the background like you see when you look at lightbox
scripts. I am trying to get some code from other plugins but it is
kind of a mess.
Do anyone of you know how to fade out the background add an overlay
with an opacity, to cover the entire page?
Thanks,
Ryan
