Footer image repeat with CSS?

Ok, in this page > http://adsphoenix.com/, there is one big image that seems to repeat-x only at the bottom of the page. I am talking about the big gradient that fades from the "dark forest greyish green" to the "forest green."

If I need to post the code I want to apply it to I can, but I am not doing it now because I don't have any code to apply to it to, I just want to know how it can be done using CSS and XHTML.

I am using an external style sheet by the way..


I am sure I will have to post some code, so If I really need to I will make up a basic CSS layout and post all the codes I will be glad to.

Thanks in advance!

It's applied to their footer div, which spans 100% the width of the page. they're not really doing anything special there, or hard. Post your code, and I (or someone else) will show you how to do it. A general idea though would be:

#content {
width: 100%;
height: 600px;
background-color: #FFF;
}
#footer {
width: 100%;
height: 300px;
background: green url(../footer-gradient.gif) repeat-x;
}

<div id="content">content</div>
<div id="footer">footer</div>

If that's all it is I can do it.
If I do have any questions I'll post it.


Thanks for helping out a new coder.
