If you create a table which has some cells with percentage based heights and
some cells with absolute heights, then sub-blocks which use percentage based
heights will not function.

Is this only a problem in quirks mode?

Comment 2

In standards mode Mozilla does not seem to honor the height percentage at all:

CSS2 does not exactly specify what the correct behavior is:

  http://www.w3.org/TR/REC-CSS2/visuren.html#containing-block

Here it is very clear that the minimum WIDTH should be the viewport:

   The width of the initial containing block may be specified with
   the 'width' property for the root element. If this property has
   the value 'auto', the user agent supplies the initial width 
   (e.g., the user agent uses the current width of the viewport). 

However, it is not as clear for height:
 
   The height of the initial containing block may be specified with
   the 'height' property for the root element. If this property has
   the value 'auto', the containing block height will grow to 
   accommodate the document's content. 

However, it's pretty important to infer that the same comments about the user
agent using the width of the viewport as the initial width should be applied to
the height as well, otherwise there is no way to have a block fill up the viewport.

While I still think that my comment about height percentage in standards mode is
valid, it appears that IE does the exact same thing that Mozilla does. 

Therefore, it looks like this is only a bug in Quirks mode.

Comment 5

[Eli Friedman]

Standards mode rendering is ignoring percentage heights on variable-height
blocks (see http://www.w3.org/TR/REC-CSS2/visudet.html#x10)

Is there any reason to add a quirk for this?
