How to begin to troubleshoot css display

Hi…I just created a site and my co-worker has ie 8.0.601.18702…It seems that the whole navigation which is css based is not showing up on her browser…Where do I even begin to troubleshoot was is going on…is it possible that she has css disabled or something …where would I check for that… Even her background color looks different than on my browser…

Here is my CSS

Hi, I think It would be of more use If you could provide a link. So we can check it as well in IE8

well, I can’t …it would require username and password…any other ideas of what it could be or what I could look for or what tools to use to debug…is there something out there that lets me view my page in multiple ie versions?

Alternatively if you could give us the HTML source code of the page (ie, what you get if you load the page and go to View > Source), rather than the ASP file, that would help.

It had to do with this line of code

<!-- Provides File Download dialog logic –>
<script type=“text/javascript” src=“Scripts/FileDownLoadUI.js”></script>

and this article solved my problem… I moved the code into header section which required me to modify the code a bit but it worked

Why do I receive an "Operation aborted" error message when I visit a Web page in Internet Explorer?

So we do not where to find the problem, it is best to provide a link, or source code.

I’d recommend opening the page in firefox and use firebug to try different things and edit elements.
