Description Gérard Talbot (no longer involved) 2008-11-28 05:41:00 UTC
CSS 2.1 & 3 Support in KHTML webpage needs to be updated
========================================================

Hello all,

I spent quite a bit of time yesterday updating

Interactive CSS 3 Background tests
http://www.gtalbot.org/DHTMLSection/InteractiveCSS3BackgroundTests.html

and found that 

http://www.konqueror.org/css/

was, in my opinion, quite outdated. The website

http://www.css3.info/preview/

suggested that several CSS 3 properties were supported (albeit with the -khtml- prefix).

I have sent today an email to Allan Sandfeld.

Regards, Gérard

I think large portions of that are outdated. ;)
Comment 2 Gérard Talbot (no longer involved) 2009-01-26 13:06:35 UTC
Suggestions:
1- 
A "yes" cell should be white on green background-color;
A "no" cell should be white on red background-color.

2-
"partial" or "incomplete" should be a possible choice.
A "partial" or "incomplete" cell should be black on yellow background-color.

It's possible to use light green and light red background-colors and to use black color for text like at

http://www.opera.com/docs/specs/presto211/css/index.dml
http://msdn.microsoft.com/en-us/library/cc351024(VS.85).aspx#selectors
http://www.webdevout.net/browser-support-css#css2units

For darker green and darker red background-colors:

http://www.quirksmode.org/css/contents.html#t10

3-
Many (if not, all!) CSS support and compliance documentation charts are presented by section of specification instead of alphabetical order of property names.

eg
http://www.webdevout.net/browser-support-css
https://developer.mozilla.org/En/Mozilla_CSS_support_chart

I know this isn't a Konqueror bug, however it isn't a documentation bug either, well it kind of is, but the documentation project doesn't have access in order to fix anything and I think it would be better for the Konqueror devs to look at getting it fixed. Maybe one of the Konqueror devs can forward this on to the correct person who can update their website?

Richard,

I agree with you that this bug may not be a Konqueror bug nor a documentation bug. If you tell me how (with correct application field, with correct product field, with correct component field) to file this bug, then I will resolve this bug 176306 and create a new bug report to report it accordingly.

If you visit 
http://www.konqueror.org/css/
you'll see at the bottom of the page that such page is "Maintained by konqueror.org Webmaster" <webmaster konqueror org> so maybe we should contact such webmaster (add <webmaster konqueror org> to CC list?).

+CC Allan Sandfeld

I believe Product for this bug should be www.kde.org
and then
Component should be general

7971 PASSED testcases

1341 FAILED testcases

7971 / 9312 = 85.60% 

----------

44 testcases are considered INVALID; if I apply stricter rules, then there are more than 44 invalid testcases.

 9 testcases UNKNOWN because I do not have a color printer and Konqueror does not have a print preview feature (Folks, please vote for bug 258634 )

 2 testcases: hangs or refuses to print: I need someone else to confirm + verify this.

 2 testcases UNKNOWN because of several characters not displayed possibly due to font availability; I need someone else to confirm + verify this.

Comment 9 Christoph Cullmann 2024-05-06 18:38:42 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
