Yes, exactly that (and your bug report is almost two year old :-) It is surely undesirable. The reason I said it is "allowed" is that the spec at <http://www.w3.org/TR/CSS21/visuren.html#bfc-next-to-float>, says "CSS2 does not define ... by how much said element may become narrower". So making a b.f.c. arbitrarily narrower than defined by section 10.3.3 is not "prohibited" (and when the box is made "narrower" than strictly required by the presence of float and margins, we have those phantom margins/gaps on one side or another, ). Of course this is an attempt of a "formal" reading of the spec. I consider that a bug :-) Best, Bruno -- Bruno Fassino http://www.brunildo.org/test ______________________________________________________________________ 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/
