Gecko is the only impls that does not collapse the bottom margin of a child when the parent's (of auto height) min-height exceeds the used height of the child. All other impls collapses the bottom margins regardless of the min-height of the parent. This came up as CSS2.1 issue 79 back in 2008, <http://lists.w3.org/Archives/Public/www-style/2008Nov/0109.html> from this message. <http://lists.w3.org/Archives/Public/www-style/2008Sep/0081.html> I believe the current behavior as seen in Gecko is what is suggested by the prose in the text. Neither bottom margins in example 3 or 4 in this test case are adjoining. <http://css-class.com/test/css/box/margins/collapsing-with-min-height.htm> Same here where Gecko that does not collapse the bottom margin of a child when the parent's min-height exceeds the used height of the child. <http://www.brunildo.org/test/collminmax.html> -- Alan http://css-class.com/ Armies Cannot Stop An Idea Whose Time Has Come. - Victor HugoReceived on Tuesday, 21 September 2010 12:22:37 UTC
