see http://www.w3.org/TR/REC-CSS2/visuren.html#floats - it explains the correct behavior in detail. A block element should be behind a float (this is the bug here), but an inline one, if positioned (and this needs to be done actively) so that it is over top of the float, should be above it.

This problem also occurs with the non floating H2's on my homepage, http://www.fas.harvard.edu/~dbaron/ . The page may be changed, though.

This was fixed by your checkin two (?) days ago.

Actually, it was only fixed in some cases. I am changing the URL from http://www.webstandards.org/ie/box_vert.html (where it is now fixed) to http://www.w3.org/Style/CSS/Test/current/sec5525c.htm because the problem still occurs when the float started before the box level element. Then the inline elements are on top, correctly, but the backgrounds do not stack correctly. See the sixth test case in the above URL.

Viewer (99-01-27) now crashes on the above URL. Raising priority to P1 and changing title. Display issues need to be fixed after crash is fixed.

If this helps, I get the following GPF: VIEWER caused an invalid page fault in module RAPTORHTML.DLL at 014f:005c030f.

Setting all current Open/Normal to M4.

I fixed the crash; however the page still evidences some layout problems so I'm leaving the bug open until I dig into it furthur.

Modified title from "padding and border bleed over top of floats ; crashes viewer" to "static background/border bleed over top of float background and border" Also, another example of this problem is http://css.nu/exp/layer-ex3b.html .

This seems related to 1413.
