I not sure why this happens. I see that moving the position of the overflow box by a top margin (positive or negative) causes the overflow box to not ignore the left margin with -100px and for the overflow box not to be shorten by the float [1]. The last test with the overflow box with margin-top:-0.01em doesn't seem to be any lower visually. 1. <http://css-class.com/test/temp/overflow-floats-neg-margins.htm> -- Alan http://css-class.com/ Armies Cannot Stop An Idea Whose Time Has Come. - Victor Hugo ______________________________________________________________________ css-discuss [cs...@lists.css-discuss.org] 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/
