CSS Tweaks For InternetExplorer Compatibility

Need some help formatting an iframe on an existing site: [login to view URL] In firefox the iframe in the body of the article shows with the correct background color, but in IE it has a white background color. I would like the coder to dig into the CSS and make the appropriate tweaks needed to get the background color to match the grey background elsewhere on the site. In addition, in both IE and in Firefox there is a darker grey line at the top of the image of the woman typing in the body of the homepage. That shading is something being caused by the CSS, not the image itself. So please fix that as well. These should be relatively straightforward and quick CSS fixes. I will provide FTP access.
