I have building my website, and a particular problem with the way that Firefox renders the pages of the site's forum has given me some grief. On all other parts of the site, there is some margin-bottom space between the bottom of the main container and the bottom of the browser window. But in Firefox (at least on Mac), the bottom of the container seems to stick to the bottom of the browser window. The CSS file is in common, but there are additional ones for the forum.
An example link is the forum's index: http://www.chopinmusic.net/forum/
If anyone could take a look at the code and give me a clue as to what's going on, I'd be quite thankful!
Thanks in advance,
