Trevman,I thought u were talking about tags style of fields, but u were talking about attribute of tags style.
I did not know it's possible. Nice to know.
Anyway,In microsoft site, it says that IE DOES SUPPORT CSS2:
"Microsoft Internet Explorer 5.0 supports the latest in World Wide Web technologies for easy and fast development of Web-based applications. These technologies include dynamic hypertext markup language (DHTML) behaviors, XSL, XML 1, HTML 5, cascading style sheets version 2 (CSS2), Document Object Model, and ECMA-262 compliant scripting. And Internet Explorer is modular so developers can use portions of the code to enhance their own products. Version 5.0 also automates functions that traditionally fell to IT administrators in corporations."

Also, in other site:
"Style sheets are governed by two specifications: CSS1 and CSS2. Netscape 6 is currently the most compliant browser, with Internet Explorer 5.5 not far behind. Both Internet Explorer 4 and Netscape Navigator 4.x support style sheets to some extent."

So, in general there is almost full support in css2, by IE5+ AND full(?) support by NS6.
Maybe the feature u r offering is one of these which r supported only by NS6 (as u suggested).
Nice to know this feature anyway.
Thanks.
