149348 - Addition of a DTD address causes elements on page to shift

Status: RESOLVED DUPLICATE of bug 153032

(Core :: Layout, defect, P3)

Description

[Ari Pollak]

Under Mozilla 1.0rc3:

First go to http://www.ebnj.net/index.php - notice on the top left and top right
sides of the page, the images which create the rounded border?

Now go to http://www.ebnj.net/weird.php - those same images have shifted about 4
o r 5 pixels down, and in the case of the bottom ones, 4 or 5 pixels up.

Why is this a problem, you ask? The only difference between index.php and
weird.php is the address "http://www.w3.org/TR/REC-html40/loose.dtd" inside the
DOCTYPE tag at the top of the page. It actually doesn't seem to matter what
address you put inside the quotes.. as long as there's some kind of text in
there, the images on the page will shift.

Oh, I should also note that this works fine in IE 5.5.

This also happens when the DTD is set to XHTML 1.0 Transitional.

Attachment: web page without table cell problem (no URL in DTD)

Attachment: single-pixel gif file used with web pages to cause table cell problem

I've submitted three attachments to demonstrate a problem that occurs only if
the URL of "http://www.w3.org/TR/html4/loose.dtd" is included in the doctype at
the beginning of the page.

home.html shows table cells that are ignoring the height attribute in the td
tag.

home1.html shows table cells that are honoring the height attributes.

The only difference between the two html files is the presence of
"http://www.w3.org/TR/html4/loose.dtd" in the doctype in home.html but not in
home1.html

Forgot to mention that the table cell sizing issue shows up on Windows NT SP6
with the 1.0 release of Mozilla -- don't know if it also shows up on other OS
variants.

Since problems caused by including a DTD address show up on Linux AND Windows, I
think the odds are good that this affects most if not all OS variants of Mozilla.

do you know if this bug has been fixed or not before you close it? (considering
this bug came BEFORE the duplicate bug)

Any cases where it's not fixed are duplicate of bug 22274, anyway.
