Is there some typographical justification > for that behaviour, or is your decision purely pragmatic? Pragmatic. In the thread, you guys pointed out several browser bugs related to rule 3 violations, but they are inconsistent and clearly bugs (for example, FF in some cases does things "correctly" when you load a page with a certain size, but not if you resize a page to that size). The one change I've made to rule 3 may not have great theoretical justification, but it's easy to talk about and everyone treats it consistently and interoperably. >> Suggested text: >> | A left-floating box that has another left-floating >> | box to its left, where the latter box's right edge >> | is to the right of the original left-floating box's >> | containing block's left edge, may not have its right outer >> | edge to the right of its containing block's right >> | edge.

New rule 3 text (I overcorrected for "outer edge"): | The right outer edge of a left-floating box may not | be to the right of the left outer edge of any | right-floating box that is to the right of it and | whose left outer edge is to the left of the | left-floating box's containing block's right edge. | Analogous rules hold for right-floating elements. New rule 7 text (slightly cleaner): | A left-floating box that has another left-floating | box to its left, where the latter box's right edge | is to the right of the former box's containing | block's left edge, may not have its right outer | edge to the right of its containing block's right | edge. (Loosely: a left float may not stick out at | the right edge, unless it is already as far to the | left as possible.) An analogous rule holds for | right-floating elements. ~TJ
