Hi all,

We have the following questions about the Microsoft testset 
(available at: http://samples.msdn.microsoft.com/ietestcenter/css.htm)

css\chapter_16\Rules text-align-white-space-003.htm

We consider both test as incorrect tests: only pre and pre-line (not
pre-wrap) cause text-align value 'justify' to be replaced by its initial


#22 is the Unicode character for 'Synchronous Idle', but no font was
found that displays it as mentioned in the test description.


Looks like IE8 specific behavior.


Whitespace is preserved in the table, so whitespace between <table> and
<tr> is considered non-empty content and is wrapped in an anonymous
table-row and an anonymous table-cell.


CSS 2.1 specification does not specify how extra table height space
should be distributed over the rows. Since a cell-height percentage
computes to auto, all rows will get an equal part of the remaining
space. A more sophisticated algorithm could inspect cell and row
percentage heights and try to satisfy them.


We consider this test as invalid test: In div1, the computed value of
outline-width is 0, because outline-style is none (the default value).
The 'outline-width: inherit' inherits this computed value, so the width
of the outline is zero.


The DOCTYPE of this test is XHTML 1.0 Transitional in which there's no
baseline space reserved below an image. This causes the images to
overlap slightly. Changing the DOCTYPE to strict will results in the
correct output..


Incorrect test: the computed value of property border-width at element
'body' is 0, because border-style is 'none'. The value 'inherit'
inherits the computed value, so at element div.test the border-width is
also 0 and no rectangle is shown. (Chrome, FireFox and Opera render this
correctly, by displaying only one square).

Robert Stam
