Is this normal behavior or is it a bug? >> This does not happen in Opera or IE. This is not a bug you are observing, but "collapsing margins" instead. See the following wiki page for more information and links. http://css-discuss.incutio.com/?page=CollapsingMargin You can also google "escaping margins" to find some of the early discussion and links to pretty decent demos of what was considered a "bug" at first (four years ago). Here's a link to a css-d thread - Joe's demo is still online - http://archivist.incutio.com/viewlist/css-discuss/7423 And Micah's page - http://www.ugcs.caltech.edu/~takoyaki/css-test/escaping_margins/ W3C specs - http://www.w3.org/TR/REC-CSS2/box.html#collapsing-margins I hope that helps, ~holly ______________________________________________________________________ css-discuss [EMAIL PROTECTED] http://www.css-discuss.org/mailman/listinfo/css-d List wiki/FAQ -- http://css-discuss.incutio.com/ Supported by evolt.org -- http://www.evolt.org/help_support_evolt/
