Problem with canvas theme structure (footer position)

Hi guys,

I’ve been working on this website (http://indiecork.com/) and all of a sudden it’s structure went pear-shaped. The only two files I’ve been working on are the custom.css and the footer.php. I’ve a feeling it’s the footer.php that may be the problem as it seems the footer has gone upwards, maybe an unclosed div but I can’t see what could be the problem. Any ideas on how I should go about this? Thanks.
