fendeanson: Thanks for the quick reply.
While I'm agreeing with you that all modern web browsers support two classes, I was trying to gauge how far back this practice is supported.
For example, IE4 and NN4 don't support two classes, and I admit, yes, those are archaic web browsers...but are there any other browsers/versions that might only interpret the second class, or neither one?
Simply put, is there any kind of documentation that explains a little more about the "two classes" practice in a variety of web browsers? I've searched through this forum and Google-d Eric Meyer to no avail.
