I agree with your proposal, Wendy. Thank you for the updated CSS-TECHS issues list. Regarding Chuck Baslock's question [1], I cannot find a Mac browser that the example works in either (Chuck tested it in a variety of Windows browsers). The alternative example below does work in the following browsers: Mozilla 0.9.7 Mac IE 5.5 Mac Opera 5.0b5.465 Mac iCab 2.5.3 (Mac) IE 5-6 Windows Netscape 4.7 Windows (border is only as wide as the text in N4, of course) Netscape 6.2 Windows Opera 5 Windows AOL 6.0 Windows Someone else may know a shorter and more elegant way to write it, though. Example. <HEAD> <TITLE>Redline with style sheets</TITLE> <STYLE type="text/css"> H1 {border-top-width: 2px; border-top-style: solid; padding-top: 4px; border-color: red } </STYLE> </HEAD> <BODY> <H1>Chapter 8 - Auditory and Tactile Displays</H1> </BODY> End example.
