Floating elements should not overlap when space is to tight. This is described in [1]: If the current box is left-floating, and there are any left floating boxes generated by elements earlier in the source document, then for each such earlier box, either the left outer edge of the current box must be to the right of the right outer edge of the earlier box, or its top must be lower than the bottom of the earlier box. Analogous rules hold for right-floating boxes. [1] http://www.w3.org/TR/REC-CSS2/visuren.html#floats I know this is different from how NS traditionally lays out floating images. I think the time has come to change that behavior -- or, alternatively -- let floating text elements behave differently from floating images.
