Thank for responding in a timely manner. I changed all the id="module" to class="module", but no luck. The site still looks retarded.
I don't think it's the div's that's causing it. It has something to do with the table's alignment. Actually, I'm not sure, so that's why I'm asking here.
I have a container element called container that contains everything in the body, and it's width is 900px. The table's width is set to 100%. I don't know if that has anything to do with it, though.
