Add a different stylesheet for IE.
Add this small code with appropriate stylesheet url in you web pages.
Code:
<script language="javascript" type="text/javascript">
<!--[if IE]>
if(screen.width>800)
{document.write('<link rel="stylesheet" type="text/css" href="other.css" />');
}
else
{document.write('<link rel="stylesheet" type="text/css" href="800.css" />');
}
<![endif]-->
</script>
Play with the width property of the different div layers to fit it accurately.
Hope this helps.
