I’m having this problem on Safari and Firefox. When the page loads, everything is okay, but when scrolls, the div on the back doesn’t follow it, stays where it loads.
Please check here:
I haven’t had any time to try to find a fix, but the reason for the problem you’re having is from the height: 100% for the two rulesets in your CSS and the way Firefox/Safari handle it. Actually only one of those height: 100%'s may be the cause of the problem.
I was going to suggest a simple fix of making a background image for the body that consisted of the white background and gray (umm… blueish-gray) borders. Then just repeat that horizontally. But then I noticed that your body is already using the graident background image. So that wouldn’t work so well.
I’ll try playing around with a few ideas and let ya know if I come up with something. If I don’t post something here, it’s because I haven’t figured it out… or I had one too many
