Footer Full Width problem

Hey Guys,

I am trying to get a full width (100%) footer working, but for some reason the footer keeps a small margin around it.

example

Anyone know what causes this?

My code is as follows:

#footer{
   background:#000;
   width: 100%;
   height: 60px;
   margin-bottom: -10px;
   clear: both;
   text-align: center;
	}
