Ingo, Thanks very, very much for your explanation. I didn't actually see anything happen in Firebug when I selected #twocolumn and moved my mouse near the borderline. What should I have seen?
But of course, your solution worked. I'm very grateful. Just to be clear: the CSS in those divs is part of a pre-built commerce package, whose author I'm doing some work for. He freely admits that the current CSS is a mess, and has a project going to build far better templates. So we'll need to see what, if any, effect the change in those attributes has in other areas (the person who built the existing CSS is long gone). But now we know the problem. And I'm very appreciative for your help. -- Thanks, Tom Tom McNeer MediumCool http://www.mediumcool.com 1735 Johnson Road NE Atlanta, GA 30306 404.589.0560 ______________________________________________________________________ css-discuss [EMAIL PROTECTED] http://www.css-discuss.org/mailman/listinfo/css-d List wiki/FAQ -- http://css-discuss.incutio.com/ List policies -- http://css-discuss.org/policies.html Supported by evolt.org -- http://www.evolt.org/help_support_evolt/
