CSS Test Suite Results: Opera 3.51 for Windows 32-bit
Previous Versions of This Page
The list that follows is a list of bugs in the browser, that is, what is
described is in error. I have also included a few partially supported
features as bugs.
- Last run through entire suite: 3.51
- Last run through existing bugs to see if they still exist: 3.51
- I have to press the "Stop" button to get the page to display. When I
do, the page shows up fine.
- Pseudo-elements should not be allowed at the beginning of selectors.
- The extra spacing under first-letter in a large font probably shouldn't
appear. -- the default line-spacing for :first-letter should be 1 or slightly
The first test is a mess: the floats are not high enough and should not
cause line breaks.
In the second test, the text should flow around the floats, not
In the third, fourth, and fifth tests, the floats should be carried
to the next line; they should never make their parent expand.
In the sixth test, the paragraph should be even with the text. (This
rule, however, is questionable. See my posts on www-style.)
In the eighth test, the float inside should not widen the DIV outside.
Padding and border of inline elements should not change the line height. (replaced elements excepted)
auto margins on replaced block level elements make a huge mess.
They should not cause the width to change - ever! (They can for non-replaced
elements if width is
Padding, border, and margins on inline elements are ignored, except
that the margins show up on the right and left.
The document does not load completely with stylesheets turned on.
- Body margins are displayed as padding.
font-family: cursive doesn't work very well because the
default cursive font is "Times New Roman." Things should come out a little
better just using the internal TTF font stuff. Of course, the fonts can be
fixed up using a very well hidden part of a dialog box (one doesn't
expect the CSS fonts to be underneath all the HTML stuff), but most
users won't figure that out.
- The font "serif" should be the same as the default font, at least in
the initial configuration. (For me, serif was Georgia, and the default
was "Times New Roman.")
bolder should not be any bolder than
is a relative descriptor, but this misunderstanding may have been due to
an early incorrect version of the W3C CSS Test Suite.
- Font weight 500 should probably be rendered as bold, as per the example
in the CSS2 spec.
Backgrounds of inline elements should not cover the line height. The size
of the background is determined by the top and bottom padding of the inline
The background image tiling runs wider than the paragraph on initial load -
it extends to where the paragraph would be without the scrollbars. However,
if the scrollbars are removed and brought back, it is OK.
There is extra spacing around the links at the bottom of the page.
text-decoration spans children, the image should be
underlined. What should have been said was that it should not be overlined.
- The following
vertical-align does not work:
Middle align should align the middle of the image with the point halfway
above the x-height of the parent text.
text-bottom align is ignoring descenders.
Percentage aligns appear to be relative to the font-size instead of the

line-height and should not
be converted to positive ones, but, rather, ignored.
- 5.5.02, etc.
- The table width algorithm has problems with CSS margin and padding
properties. I also think the TABLEs should, according to CSS, be the
whole width of the page, but this is inconsistent with historical
- The right margins on inline elements are being applied on every line.
The negative margin-left causes strange effects at the right edge where there
is a line break.
- 5.5.06, etc.
Negative padding values are not allowed. It causes a number of other problems
that I will not mention.
Top and bottom padding on inline elements is not applied. It should
at least be applied up to the edge of the text on the next line, but
preferably to its full extent.
padding is set on all edges of an inline element,
the top and bottom padding should not effect the line
Border on inline elements should not affect the line spacing.
The line-height should not be treated as padding; if there is no
padding set, then the border should touch the text on the top and
bottom. However, it should not come closer than that, as it does
with double borders in in 5.5.18b and 5.5.20b.
border-color does not work.
Table cell borders do not seem to show up, although it may be only the
color that doesn't work.
The image in the second example should appear after the paragraph.
The same type of problem occurs in the sixth example if one makes the
For some reason the page is incorrectly given a horizontal
scrollbar and made considerably wider than the viewport, which messes up the
floats and certain padding. This is new in 3.51.
The floats run all the way across the page. They should carry to
the next "line" when they no longer fit within their parent.
The bottom border of BODY should have space below it when the page
is not long enough.
The list marker images don't have enough padding after them. The
idea of the CSS2
marker-offset is what should stay constant.
- With a small font, the text inside the table is carried to a second
line even though there is room to widen the table. That is, the bullet
is not counted in the line-width calculation. (See my comment on
There should not be an indent before the marker letter A, because it
is simply the first inline box in the line.
When an invalid keyword occurs, the entire property declaration should
be ignored. This occurs in both the

Other Bugs I've Heard About (not from CSS Test Suite)
Opera does not support background-images on TD elements. See a demo by
Jukka Korpela. He also shows a workaround. (reported by JK)
line-height on OL elements causes the
numbers/letters not to be baseline-aligned. This is bad behavior,
although not strictly inconsistent with the spec, I believe.
However, it is inconsistent with the CSS2 marker model, which I think
is how lists should be rendered. Sue Sims has a demonstration of
this bug. (reported by SS)
list-style-image marker images are not loaded if the
list is within a table. However, if the image is already in the
cache, they work fine. (reported on c.i.w.a.s)
Opera has some problems with the inline box model. However, its
performance on my inlinetest is better
than any other current browser.
Opera does not seem to support background color on a
I was told this is fixed in 3.51, but I haven't
checked. I'm also not 100% sure that background-color should be
supported on a
A border on BODY in a short page
should have extra margin-bottom.
