My action from telcon today -- proposed changes for min-height/max-height in margin collapsing
Change 1 -- remove min/max height text from bottom-margin rule in 8.3.1 [1]:
The bottom margin of an in-flow block-level element with a 'height' of 'auto'
<DEL>and 'min-height' less than the element's used height
and 'max-height' greater than the element's used height </DEL>
is adjoining to its last in-flow block-level child's
bottom margin if the element has no bottom padding or border.
Change 2 -- add a clarifying statement in 10.7 [2]
These steps do not affect the real computed values of the above properties.
<INS>The change of used 'height' has no effect on margin collapsing except as
specifically required by rules for min-height or max-height in "Collapsing Margins" (8.3.1)</INS>
I still not sure what exactly is a concern in 10.7. Does this change sound reasonable? We can't really say "min-height and max-height have no effect on margin collapsing" because non-zero min-height prevents collapsing through an otherwise empty element...
