Using Firebug to see where the difference is coming from, it appears that the height of the #header is different in both of these examples. Here are two images showing the problem design (http://outtacontext.com/images/wrong.png) and the correct design (http://outtacontext.com/images/correct.png). The second one is the correct one. There is too much space in the first one. But I can’t tell what’s defining that extra space. I can’t find it in the css. Every other page and post on the site displays correctly.
Any help you can give would be appreciated. Thanks.
