Moving Background Image

Hey!

How do I make an image go to the bottom of my div?

#header {
	width:100%;
	height:80px;
	background-image: url(/images/bg_002.gif);
	background-repeat: no-repeat;
}

Code (markup):

That is what I have so far although it is not needed, I just want to know what I put to make the image go to the bottom as opposed to starting at the top.

 

#header {
width:100%;
height:80px;
background: url(/images/bg_002.gif) no-repeat no-repeat bottom center;
}

 

Thank you!

 

your welcome
