Description User image tronster321 1999-04-15 04:56:46 PDT
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.
Comment 1 User image troy 1999-04-15 08:24:59 PDT
Rick, I think this is a DUP. It's a problem with content not nesting inside the
DD tag like it should
Comment 2 User image rickg 1999-04-26 00:14:59 PDT
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.

Comment 5 User image kipp 1999-09-16 20:45:59 PDT
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.
Comment 6 User image rickg 1999-12-21 13:37:59 PST
Fixed by improvements to elementtable.
Comment 7 User image Chris Petersen 2000-01-31 16:21:54 PST
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.
Comment 8 User image rickg 2000-02-06 22:24:40 PST
The content model is now correct; and layout is goofy. Reassigning to block-boy.

Comment 13 User image buster 2000-06-16 15:10:01 PDT
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.
Comment 14 User image Jim Roskind 2000-06-17 12:44:36 PDT
Cleaning up status whiteboard by marking beta2 minus (6/15 has passed)

This is also what buster (on sabbatical above) just suggested.
Comment 15 User image David Baron :dbaron: ⌚️UTC-8 2000-07-03 16:54:25 PDT
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.
Comment 16 User image David Baron :dbaron: ⌚️UTC-8 2000-07-21 11:48:20 PDT
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;
Comment 17 User image David Baron :dbaron: ⌚️UTC-8 2000-07-21 11:56:54 PDT
I think the following is the correct patch.  Do you think it's worth having the
2d and 4th added rules?

Note that there are currently no other UA-level declarations of text-indent, but
if there were, the 2d and 4th rules would mess them up.

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

Comment 20 User image Hixie (not reading bugmail) 2000-08-31 14:38:16 PDT
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?
Comment 21 User image David Baron :dbaron: ⌚️UTC-8 2000-08-31 14:46:57 PDT
No, I didn't test, but apparently everything else is 40px.  Do a quick test if
you want...

Comment 25 User image Hixie (not reading bugmail) 2000-09-14 06:04:05 PDT
I assume that the "margin: 40px" bit should read "margin-left: 40px".

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

Compare the two test cases with legacy browsers. They should be the same in
Comment 31 User image Chris Petersen 2000-10-24 13:58:26 PDT
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.

Comment 33 User image fantasai 2000-11-05 16:07:39 PST
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;

Comment 35 User image Hixie (not reading bugmail) 2000-11-15 18:22:02 PST
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.
Comment 36 User image fantasai 2000-11-15 19:34:52 PST
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...)

Comment 47 User image Hixie (not reading bugmail) 2001-02-22 18:05:04 PST
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.

>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. ^^

'none' isn't a valid value for the 'content' property.  'content: none' should

Indentation of DD outside of DL no longer works.
Comment 59 User image Mats Palmgren (:mats) 2001-08-06 20:52:05 PDT
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.

Comment 63 User image rubydoo123 2001-09-21 11:50:02 PDT
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?
Comment 64 User image rubydoo123 2001-10-11 17:17:35 PDT
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.
Comment 65 User image David Baron :dbaron: ⌚️UTC-8 2001-10-11 17:27:59 PDT
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.
Comment 66 User image rubydoo123 2001-10-12 10:42:51 PDT
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?
