Each test has the element has the only child of body.

Since the BODY element has hasLayout=True by default [2] in IE5~IE7 then all these 'margin-top's will disappear [3]. What Phillip has said is correct. You may want to ask Alex Mogilevsky about hasLayout. He may be just down the corridor at your work. :-) [1] http://www.satzansatz.de/cssd/onhavinglayout.html [2] http://msdn.microsoft.com/en-us/library/ms533776(VS.85).aspx [3] http://css-class.com/test/css/box/margins/iehaslayoutmargins.htm Alan http://css-class.com/test/
