[quirk.css]DD not in DL should have text-indent, not margin


(Core :: CSS Parsing and Computation, defect, P5)

For the above URL, in Netscape 4.x and IE 4 the DD tag will give the
appearance of a paragraph with the first line tabbed.  In the 1/9/99 developers
release, when viewing the page, the DD tags make the first word in each
paragraph appear tabbed but then two newlines are "added" before the next line
of text is displayed on the screen.

End Of Line.

Rick, I think this is a DUP. It's a problem with content not nesting inside the
DD tag like it should
Assignee: rickg → kipp
Kipp: This is one yours. The DD tags aren't the problem. First, the <DD> is not
wrapped in a <DL>, so we don't get the "indent". I think you need to address
that. Second, if we *do* wrap the <DD> in a <DL>, then we get extra unwanted
vertical whitespace. Note that I do have another <DD> bugfix that may or may not
be checked in by the time you see this, but it's unrelated.

Here's a simple test case:

  <table width=600 border=1>
          <dd>This</dd> page contains an archive of songs created by me, Todd
Hartley (aka Tronster).<br>
          <dd>To </dd> download the songs, click on the link to the file type
you support under the "format" column.
This could probably be done in a way similar to LIs not in ULs.  See bug 1049.

Summary: The DD tag has some interesting results. → {compat} The DD tag has some interesting results.
Navigators behavior of ignoring (entirely!) is a serious bug. The only real way
to handle this is in the parser - rick/harish: maybe the thing to do is when
processing a /DD tag in quirks mode is to discard it and then let your fixup
logic repair the resulting (occasional) damage.

There is really nothing I can do here in layout land.

Fixed by improvements to elementtable.
This problem is still occurs in the latest build. The text after the </dd> should 
not break and start a new line. After talking with Rick, I will change component 
to Layout.

I looked at this a little bit.  It will be very hard to fix. The problem is the 
behavior is contextual in a way that cannot be expressed in CSS.  So html.css 
needs to describe the basic behavior, and the frame constructor code will have 
to do some wampum juju to cover the other cases.  Suggest nsbeta3.

This is also what buster (on sabbatical above) just suggested.
I think this *can* be fixed purely in CSS, although it's a bit complicated and 
should be in quirks.css only.  I'm assigning it to myself to work out the 
correct fix.

Target Milestone: M17 → M18
I think this would be fixed by adding the following rules to quirks.css:

dd {
  text-indent: <some value>;
  margin-left: 0;

dl > dd {
  text-indent: 0;
  margin-left: 40px;
I think the following is the correct patch.  Do you think it's worth having the
2d and 4th added rules?

Ian - assigning this to you since it's quirk.css.  Patch that should fix it is

Assignee: dbaron → ianh
Thanks David.

Seems like a bit of a violent fix, but since it is quirks-only, fine. Did you
test the fix with different font sizes to work out if the indent was 40 pixels
or in ems in legacy browsers?

No, I didn't test, but apparently everything else is 40px.  Do a quick test if

I assume that the "margin: 40px" bit should read "margin-left: 40px".

That is what I have put in my quirk.css file.

Resolution: --- → FIXED
FIXED by updating quirk.css.

Not sure from looking at the test cases provided, how to verify this ?
Compare the two test cases with legacy browsers. They should be the same in
Netscape 4.7 and Netscape 6 both rendered the test files different as described 
in the original summary.

Netscape 6:
 First word is indented the remaining paragraph is rendered below.

Netscape 4.7:
 Entire paragraph is indented.
Resolution: FIXED → ---
The "valid" par of the testcase (with enclosing <dl>) is invalid; the <dd> is 
closed before the end of its content. Since this bug isn't about handling 
prematurely closed <dd>s, I'm attaching a new testcase with that part fixed.

Here's a fix for the bug itself:
In "quirk.css":

/* Quirk: DD not in DL has text-indent instead of margin (b=5119) */

-dd {
-  text-indent: 40px;
-  margin: 0;
-dd > * {
-  text-indent: 0;
-dl > dd {
-  text-indent: inherit;
-  margin-left: 40px;
-dl > dd > * {
-  text-indent: inherit;

+dd {
+  display: inline;
+  margin-left: 40px;
+dl > dd {
+  display: block;
+  margin-left: 40px;

That won't work, what if you have:

   <dd> one </dd>
   this is some text.
   <dd> two </dd>
   this is some text.

i.e., remove the <br>s from the testcase.

Yes, I realized that later..

There's a give and take here; you can't support every broken coding. From what
I see, you either have to give up handling
  - </dd> in the middle of the visual "block" (use David Baron's "fix")
  - <dd> without a preceding line break of some kind (use the "fix" above)
  - empty <dd>s (I've got a really messy CSS hack to do this)

I'll attach a modified quirk.css demonstrating the last one.

Probably the last one gives the "safest" output. IE5 can't handle empty <dd>s 

It depends on whether or not you're willing to swallow that code. =)
(I ought to attach an expanded testcase...)

Nope, you'd want the rules I just attached. (I forgot to set 'font: inherit' for 
proper <dd>s)

> BTW: very creative ;)

Ian, can you review the patch? If you like it, I'll take it to the tree...
Well, Moz with this patch and IE display all the testcases differently, so I
guess it doesn't pass review... But it's better than what we have now, and it's
a quirk so I'm not particularly worried either way, so r=hixie.

I'm curious -- why all the dt:before hackery rather than just the same
margin-left on the inline dd as the block?
>thanks Fantasai!

My pleasure.

> I'm curious -- why all the dt:before hackery rather than just the same
> margin-left on the inline dd as the block?

Because the ::before psuedo-element creates a box *inside* the <dd>;
you'd get margin space before the line break instead of after it.
I tried that at first--didn't work. ^^
sr=shaver.  Can it get in the tree?
YEs - in fact, I meant to check it in over the weekedn but I was distracted by a
regression... It will go in very, very soon.

Fantasai's change was checked in. Thanks! (quirk.css ver. 1.14)
'none' isn't a valid value for the 'content' property.  'content: none' should
be changed to 'content: ""'.
well, we're not identical to IE, but whatever... :-) VERIFIED
Indentation of DD outside of DL no longer works.
Resolution: FIXED → ---
Forgot to mention the Build ID: 2001-08-06-03 on Windows 98 SE. I have poked
around in quirk.css and found that it is this rule that is not working as it
used to:

:not(dl) > dd:before {
  display: inline;
  white-space: pre;
  font-size: 1px;
  line-height: 0;
  content: "\A  ";
  margin-right: 40px;

It seems that "font-size: 1px" is the cause of the problem - if I change it to
"font-size: 2px" (or higher, or remove it) it works again.

Are you still seeing this problem? It seems to work on 2001082803 (Win2K).
I still see this problem, 2001-09-14-03 on Windows 98 SE.
My comment on 2001-08-06 20:52 is still valid.
Why is this a valid bug? In the example that Rick gave (From 
1999-04-26 00:14), he has pcdata within the DL -- that is illegal. The only 
content allowed within the DL container element is a DD or a DT. 

Why are we spinning our wheels for invalid html?

since this deals with invalid markup, I am going to mark this bug as invalid, if 
there are issues about that, please let me know.
Closed: 22 years ago21 years ago
Resolution: --- → INVALID
Reopening.  This is a bug in our implementation of a quirk.  If you don't care
about invalid markup, then you should instead file a bug that we remove the
quirk entirely, but if we have it it ought to be right.
Resolution: INVALID → ---
The only requirement is that the text be rendered, which it is. Is the bottom 
line issue here that we do not render it like IE? If that is the case, then this 
is P5/Futured for Marc or can be reassigned to someone else who has the cycles 
to pick it up.

FIXED is a better resolution, since this bug was in fact fixed (comment 54 / comment 57), and then reopened for some other problem (comment 58 / comment 59).

But if you're citing HTML5, why aren't you filing a bug that we should remove the quirk entirely?  Would that match other browsers, or not?
