Trying to make a white background for the bottom of the page

[ChadMaestro]

Hi all. This is the website:

http://cardwells.techroom.net.nz/

I'm trying to create a background at the bottom of the page so that the the bottom bit blends in, and creates the idea that it's a background. Hopefully that makes sense?

Similar to this page here, where the white background goes all the way to the bottom.

http://hobsonvillepoint.universal.co.nz/index.php

This is the code I've tried:

#footerwhitelow
{
	background:url(http://cardwells.techroom.net.nz/wp-content/themes/kingsize/images/footerbackground.png) repeat;
	height: auto;
	width: 100%;	
	position: relative;
}

That's obviously not working, though. Any help? : )

Cheers,
Chad

Thanks, tried that but it, for some reason made a huge gap between the content and footer stuff.
