Hello,
"
Hĺkon encourages people to review the new tests in the multi-col test
suite.
"
Due to a coincidence involving clip-001 test, I examined a multicolumn
test and then examined more multicolumn tests.
I'll start with
http://test.csswg.org/suites/css3-multicol/nightly-unstable/html4/containing-001.htm
line 10 div {
font-family: ahem;
font-size: 1em;
line-height: 1em;
Issue 1
-------
Font-size will compute to 16px which is not ideal, not good for creating
an associated reftest... because not dividable by 5px.
It must be said here that reftests, by definition [1], should be using
different features, different methods of achieving layout in order to
reduce risks of false positives. If computed font-size when using Ahem
font is not dividable by 5px, then accurate, reliable baseline alignment
positioning is not garanteed, is not good.
Issue 2
-------
line 19 widows: 1;
orphans: 1;
I do not understand why widows and orphans have to be specified: is
there a need to use, specify 1? If/Assuming these declarations are
needed, then shouldn't the test be flagged as paged?
The default is
'orphans'
Value: <integer> | inherit
Initial: 2
'widows'
Value: <integer> | inherit
Initial: 2
I see the occurences of issue 1 and issue 2 in many multicolumn tests.
[1]: "The reference file uses a different method to produce the same
rendering as the test file. (...) it is necessary to use features that,
although different from the tested features"
