Description Gérard Talbot (no longer involved) 2010-04-10 00:16:47 UTC

Version:            (using KDE 4.4.2)
OS:                Linux
Installed from:    Ubuntu Packages

8 reduced self-explanatory testcases
====================================

Content width does not apply to tbody
http://www.gtalbot.org/BrowserBugsSection/Konqueror4Bugs/tbody-width.html

Content width does not apply to thead
http://www.gtalbot.org/BrowserBugsSection/Konqueror4Bugs/thead-width.html

Content width does not apply to tfoot
http://www.gtalbot.org/BrowserBugsSection/Konqueror4Bugs/tfoot-width.html

Content width does not apply to tr
http://www.gtalbot.org/BrowserBugsSection/Konqueror4Bugs/tr-width.html

The 'width' property does not apply to elements with 'display' set to 'table-row-group'.

http://www.w3.org/Style/CSS/Test/CSS2.1/20100316/html4/width-applies-to-004.htm

Expected results
================
There should be no red in the 8 pages' testcases, not even a thin red line in each and all of the 8 testcases.

Actual results in Konqueror 4.4.2
=================================
There is a thin red line in each and all of the 8 testcases.

Description
===========
Width, min-width, max-width should not apply to tbody, thead, tfoot and tr elements.

Bug entry
=========
http://www.gtalbot.org/BrowserBugsSection/Konqueror4Bugs/#bug28

Relevant quotes from CSS 2.1
============================

Section 10.2 Content width: the 'width' property
"
Applies to:  	all elements but non-replaced inline elements, table rows, and row groups 
"
http://www.w3.org/TR/CSS21/visudet.html#the-width-property

Section 10.4 Minimum and maximum widths: 'min-width' and 'max-width'
"
Initial:  	0  (min-width)
Initial:  	none (max-width)
Applies to:  	all elements but non-replaced inline elements, table rows, and row groups 
"
http://www.w3.org/TR/CSS21/visudet.html#min-max-widths

Notes
=====
- Internet Explorer 8, Firefox 3.5.8, Firefox 3.6.3, Opera 10.10, Opera 10.51, Safari 4.0.5 all pass each and all of these 8 testcases.
- When examining computed values for width and min-width for  with Konqueror's DOM TreeView tool, we can see that several table have min-width == 1px or min-width == 5px when CSS 2.1 states that initial value for min-width is 0px.
- I have no idea from where such thin red line comes from actually. I tried setting border-spacing to 0 to no avail.
- Konqueror 4.4.2, Qt 4.6.2, Linux 2.6.31-19-generic here.

Comment 3 Christoph Cullmann 2024-05-06 18:38:45 UTC

Dear user,

KHTML (and KJS) was a long time more or less unmaintained and got removed in KF6.

Please migrate to use a QWebEngine based HTML component.

We will do no further fixes or improvements to the KF5 branches of these components beside important security fixes.

For security issues, please see:

https://kde.org/info/security/

Sorry that we did not fix this issue during the life-time of KHTML.

Greetings
Christoph Cullmann
