Removing extra space at the bottom of page

Question

There is an extra space at the bottom of the document. I tried setting all the padding and margin to 0 for html, body, and the bottom div. But the space is still there. How can I get rid of this?

Here is the link to the page.

there is space, or $nbsp; . after deleting it in your root file everything should be OK.
