CSS1 Test Suite Results: NGLayout Engine
This page lists results of running NGLayout through the W3C's CSS Test
Suite, and a few other tests. However, I also have a number
of my own tests, for which the results are not listed
here.
Status of This List
- Last run through whole suite for new bugs: Build of 1998 December 19.
- Last run through existing bugs to see if they still exist: Build of 1998 December 19, with slight modifications 1999 February 03.

Bugs from Test Suite
The list that follows is a list of bugs in the browser, that is,
what is described is in error. I sometimes only mention the bug the
first time it occurs in the test suite. I have also included a few
partially supported features as bugs because, although it would be
acceptable to completely fail to support the feature, supporting it
halfway can cause unexpected results.
- 1.1
- Alternate stylesheet interface is primitive.
- 1.3
- The underlining is ugly. It does not have a stable baseline
(though it does have solid color), which it should, since
text-decoration is not inherited, but, rather, spans children.
(See Bug 1019)
(See Bug 1777)
- 2.5
- Pseudo elements are incorrectly allowed at places other than the end of
the simple selector.
(See Bug 2000 - this is now fixed)
(See Bug 2011 - this is now fixed)
- 4.1.1
-
-
Nested margins do not collapse (.six .five .seven) properly.
(See Bug 1378)
-
The non-floating paragraph is way too low (.eleven). It should not
be moved by any floating elements.
(See Bug 1279)
- 4.1.2
-
The left border is one pixel too thin on its left edge. (Note: the
pixel ruler has an extra pixel *and* starts with zero, so it acts like
the first pixel is -1.
(See Bug 1052)
- 4.1.4
-
In the first DIV, the floats are not high enough.
(See Bug 2013)
-
There is extra space between the first and second lines of text in the second DIV.
(See Bug 1279)
-
In the fifth test, the top of a float cannot be higher than the top of
a previous float.
(See Bug 2013)
-
In the sixth test (non-DIV), the floater is not high enough.
(See Bug 1279)
- 4.2,
5.5.11b,
5.5.12b,
5.5.13b,
5.5.14b,
5.5.15b,
5.5.16b,
5.5.17b,
5.5.18b,
5.5.20b,
5.5.22b
- The text of the inline elements should not change baseline when a border
starts.
- The ends of the borders are ugly. They shouldn't have diagonal edges.
(See Bug 2010)
- Margins on the top and bottom of inline elements shouldn't do anything.
- Borders of inline elements should not increase the line-height.
- Borders on inline elements should not change the baseline.
(See Bug 1606)
(See Bug 1508)
- 4.4
-
The page is a mess!!! The old list of bugs is:
-
I don't think (???) the 3px half-leading is appearing before the new
lines properly.
-
The images with border and margins should be aligned based on their
outer edges, not content edges.
-
I'm not sure the last image is quite right.
(See Bug 2014)
- 4.5
-
The BODY margin-top gets the color of BODY.
(See Bug 1580)
(See Bug 2016 - should be fixed)
- 5.2.2
-
This page is a real mess. Cursive, fantasy, and monospace don't do
what they should in the first part, but monospace somehow becomes
better when there is an alternative font-family after it. Fonts in
the DIV seem to be changing the size of fonts within - in the second
DIV, with the monospace font. There may be some other weird things
too. This is explained in bug 582.
(See Bug 1038)
(See Bug 581)
(See Bug 582)
- 5.2.5
- Judging from MSIE5, you could do a little better with the weight
900 (which also applies to the
H4 with bolder.
(See Bug 972)
- 5.2.6
- Negative values should not be allowed.
(See Bug 1039 - should be fixed now)
- 5.2.7,
5.4.8
- Line heights in ems, percentages, and scaling factors look like
they might be based on the original line-height rather than the
font-size. However, it's hard to tell.
(See Bug 585)
- Backgrounds of inline elements should not fill the line-height. The line height should also be split between both sides of the text.
(See Bug 585)
- 5.2.7
-
The BODY font size does not inherit correctly into the TABLE.
(See Bug 1044)
- 5.4.3
-
text-decoration should span children with text-decoration
set to none (including images).
(See Bug 1019)
(See Bug 1777)
- 5.4.5
-
- There is no capital letter after
.
- Accented letters are not text-transformed.
(See Bug 2015)
- 5.5.01b,
5.5.03b,
5.5.05b
-
Top and bottom margins on inline elements should not do anything, because
they do not increase the line spacing.
(See Bug 1606)
(See Bug 1508)
- 5.5.04
-
When the page is narrowed, the TABLE won't shrink past a certain
point. This may be OK. If it is maximized from a narrowed position
then display problems result.
(See Bug 2022)
- 5.5.06,
5.5.06b,
5.5.07,
5.5.07b,
5.5.08,
5.5.08b,
5.5.09,
5.5.09b,
5.5.10,
5.5.10b
-
Negative padding values are not allowed (in both CSS1 and CSS2). They
have messy effects here.
(See Bug 2012 - should be fixed now)
- 5.5.06b,
5.5.08b,
5.5.10b
- Top and bottom padding on inline elements should not
increase the line spacing and should not mess up the baseline alignment.
(See Bug 1606)
(See Bug 1508)
- 5.5.13b,
5.5.15b,
5.5.22
- 5.5.13b: The thin border on the inline element is thinner inside the table.
- 5.5.15b: The border is thinner on the bottom and the right outside the table and
thinner on the right inside the table.
- 5.5.22: The thin maroon border is thinner on the bottom and the double one varies by side.
(See Bug 1052)
- 5.5.15
- The top border is 1px (?) thinner than the rest. This is
especially visible on thin.
(See Bug 591)
(See Bug 1052)
- 5.5.17
-
Cosmetic bug: some of the borders (dotted, dashed especially) could use some work.
(See Bug 1054)
- 5.5.18,
5.5.19
5.5.20
5.5.21
5.5.22
- (Old version of suite (for tests 18 and 20 only): The
thin (top & bottom) border is thinner inside
the table.) Now it is gone.
(See Bug 1055)
- 5.5.25
- The first
P inside the table doesn't have its usual
margin-top.
(See Bug 1583)
- 5.5.25b
-
-
The image being moved up and left 30 pixels is being moved right 60
pixels instead of left 30 pixels.
(See Bug 1605)
-
The image with a positive bottom margin is causing weird effects --
this should be fixed if the margins on inline elements bug is
fixed. Also, the text in the third paragraph starts too low.
(See Bug 1508)
(See Bug 1606)
- 5.5.25c
-
-
The image in the second paragraph should end up after the paragraph since
there is no room for it.
(See Bug 2025)
-
In the sixth test, the paragraph background should not overwrite the
background of the float
(See Bug 1277)
-
Floats within tables have problems. The table, for some reason, is
way too wide.
(See Bug 1059)
-
The
CLEAR="ALL" isn't quite doing the trick. The HR
after the seventh test gets shortened. CSS Clear isn't working on
later pages (5.5.25d, etc.)
(See Bug 1808)
- 5.5.25d
-
-
There is a horizontal line running across the image that shouldn't
be there.
(See Bug 2024)
-
Also (see above), the image isn't cleared.
(See Bug 1808)
- 5.5.26
-
The top margin of the
P element isn't applied to the first
element inside the table.
(See Bug 1583)
- 5.5.26b
-
This page is messy, but I think all the bugs are dealt with earlier,
except that the yellow DIV is a little bit low.
Add bugs here??
- 5.5.26c
- Overconstrained box properties on BODY don't set margin-right to auto.
(See Bug 1300)
- 5.6.5
list-style-position: is set in ua.css on
an LI, so the test doesn't work.
(See Bug 1049)- 7.1
-
-
// is not a valid CSS comment and should result in errors.
(See Bug 1812 - this is now fixed)
-
The following bugs are related to section 7.1, but are not part of the test page itself (see my unitless numbers test):
border-width: 200; is inacceptable and should be rejected.border-width: 200 px; is inacceptable and should be rejected.border-top-width: 200 px; is inacceptable and should be rejected.
Unsupported Features from Test Suite
A: visited, A: active
(2.1) - A
and A:link are supported - the distinction is made correctly.
(See Bug 577)
(See Bug 1848)
background-attachment:
(5.3.5)
(See Bug 1045)
