css background image will not align to the bottom of the footer.

I can get it to work with no margins. But I need the margins to push the text out of the way of the image about 15px. The margins just shift my background image to the right;

My CSS is as follows.


#footer{
padding: 0 0 20px 0;
margin: 0 15px 0 15px;
background: #787746 url("../images/footer.gif") no-repeat center bottom;
bottom:0px;
position:absolute;
width:100%;
}

any ideas?

Hmm... not sure what you mean by that? Do you have a link so we can see for ourselves?
