Internet Explorer CSS/HTML validation

[javabeing2]

I am looking for a plugin or tool that can validate HTML and CSS as Internet Explorer interprets it. I develop in Firefox and often find IE misinterprets the CSS. Can anyone recommend one? I recently started using the CSE HTML Validator plugin for Firefox and love it. I'm looking for something similar for IE, where I can do a view source and validate the HTML.

Thanks

I have IE set to use CSE Validator when I "view source". It is simply a matter of selecting which editor you want it to use.
