I'm not sure if I'm doing this right, but it doesn't seem to be working for me yet.  Do you have an idea of which classes I should be putting in this tag?  Here are the sheets being inherited in the page.

http://hcecorp.com/orc/forms.css

And here is an example editor within the page

Also, when you right click in the editor the menu comes up in a weird place.  This happens in Firefox.

It would be a GREAT feature if you could have a tag to allow the editor to completely isolate itself from CSS inherited in the page.  Is this a possibility?  Thanks for the help!
