Opera 9.21 adds line. In quirks mode line is added. Opera 9.21 does not add line. IE6 and Konqueror 3.5.5 add line in both modes. Reproducible: Always Steps to Reproduce: 1. Load sample page in Mozilla and Opera 2. Check grey table row size Actual Results: http://www.topolis.lt/test/form-blues.jpg Expected Results: Some consistency between browsers.

From reading bug 41806 and bug 341891, I can tell that this is an intentional difference between quirks mode and standards mode, but I can't tell why the difference exists. Perhaps other browsers are incorrectly giving FORM elements a margin. Have you tried reporting the bug to Opera and Konqueror? :)

My favorite browser first. Others later. Will try contacting Opera and KDE.

Per HTML5, the form element is expected to have no margins in standards mode. This is now implemented in all major browsers. So this is no bug. (Only in quirks mode, a margin-bottom: 1em; is expected).

You can't justify HTML4 compliance based on unfinished HTML5 specification. Issue is old and I've already solved my problem with css.

The page was rendered in Almost Standards Mode (which is the same thing) because the doctype contained a system identifier, see http://hsivonen.iki.fi/doctype/ HTML4 did not specify rendering, so I can't base the decision on HTML4. While there is no normative definition for rendering HTML documents, HTML5 gives some hints (for example that form has no margins). Browsers have aligned to that hint. Some parts of HTML5 are quite stable, so it's reasonable to refer to them :) Sorry for not explaining the cause in more detail. > Issue is old and I've already solved my problem with css. I didn't mean to concern you. I have closed the report because it did not report an actual bug but expected bahaviour. Simple clean up. Have a nice day.
