Mysterious missing footer in IE7

[Ignatius]

I have a problem with a footer div not displaying in IE7. Looks fine in Firefox. Haven't tested it on anything else so far. The code checks out as valid HTML and CSS (Strict 1.0)

What am I missing?

Here's the page:

http://pollywogbranding.com/temp/index.html


Here's the css:

#footer {
margin-left: auto;
margin-right: auto;
width: 800px;
font-size: 9px;
color:#b1b3b5;
}

.footer_style {
	width: auto;
	height: auto;
	padding-left: 328px;
	margin-top: -24px;
	}

And here's the HTML:

<div id="footer">
<div class="footer_style">NAME AND BRAND IDENTITY BY <a href="www.pollywoginc.com" title="Pollywog, a Naming and Branding Agency">
POLLYWOG</a><span style="padding-left: 55px">&copy;2007 Bumblebee Personal Assistants</span></div>
</div>

Thanks for your help!

HTML != XHTML.

IE has issues with negative margins. Give ".footer_style" position:relative.

That fixed it! Thanks for lending your big brain.
