IE seems to not render a gap when the last div in the document is either left empty completely or if it just has text without another in it. Making it a floating element works, too, but then it offsets the hidden popup element differently in all browsers, causing more annoyance. Spent an hour and a half last night just fooling around with trial and error and couldn't get it fixed the way I wanted.
It makes absolutely no difference on my computer using IE 8.0. Removing the spans leaves exactly the same gap. The only thing that makes any difference at all is increasing the padding/margins, which increases the size of the gap (as expected), but nothing I've tried will reduce the gap or remove it completely. I wouldn't have thought floating it would make a difference, but I never thought to try that because it'll just screw up the pop-up even if it works. I don't think there's any way to float it and still have the pop-up work the way you want.Sent you a buck twenty.
Thanks. 
Updated the page. Enjoy your burrito
(unless it requires non-standard workarounds, then don't bother).
