I have a jsfiddle included. This is really just fooling around, but i can't get this background to stretch the entire viewport. I think it has to do with the background being 1000px wide stated in the jQuery script, which would make sense. But setting the divs to 100% w/h is not working to stretch that image.
Just a heads up: there is basically a large gradient i want that is scrolling the page and restarting (the jquery does that) and there is an overlay on top of it that gives it a nice effect.
Div overlay is quite simple:
<div id="wrapper">
<div id="container">
<div id="overlay" class="png-fix">
</div>
</div>
</div>
Thanks a lot crowd!
