Answer 1

Edit:

After checking your code, I noticed that you understand the theory of floating and clearing, so I checked a bit more… It seems that you have unclosed </div> somewhere, thus rendering yout div.content-bottom on a different DOM level then after the div.content-middle.

Original answer:

It’s because of the floating on your #content and #sidebar

You should use clear:both; for the .content-bottom div.
