User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030704

Setting style="background-color:red" no longer colors in the background on a
button. 

First noticed the problem while setting the style attribute of the button
through javascript.

document.getElementById(button).setAttribute('style','background:red');
Which does not work either.

I have tested this and get the same problem on several windows machines (windows
2000) and a linux machine (slackware). However it does work off a mac machine
(OSX 10.2.6).

All machines are running current-stable mozilla 1.4 downloaded today( Jul 7
2003). This was working previously with 1.4RC1 and earlier versions of mozilla

Reproducible: Always

Steps to Reproduce:
1.create button on page 
<button style="background-color:red">
2.view
3.no color showing

Actual Results:  
No background color on button

Expected Results:  
Shown background color

Murray, I cannot reproduce the problem with the testcase I just attached with a
current Linux trunk build.  Can you reproduce the problem with that testcase on
Linux?  On Windows?  If not, could you attach a testcase on which you _can_
reproduce the problem?

Sorry should have specified. Problem does not exist with html code but with
mozilla's xul language.

This attachement does not work

Hm... That testcase also works for me... Is your Linux build compiled with GTK2
or something?  This could be native theming interfering with the in-page styles...

I am not sure, how do i test that.

This also does not work for my windows 2000 installations as well.

I can reproduce it with Mozilla 1.4 on Win2K. I'll attach a screenshot of DOM
Inspector that might explain this.

Murray, you can look up your build configuration by typing "about:buildconfig"
in the URL bar.

On Windows, the issue is almost certainly native theming if you are using the
Classic theme.  Are you?  Do you see different results with Modern?

Boris, you're right about the windows platform. With the modern theme the
button's background is red. BTW, the same applies to Mozilla on FreeBSD.

[Boris Zbarsky [:bzbarsky]]

Over to bryner-- the native theming code needs to drop the nsITheme styling when
styles are applied to the button...

In my linux configuration it does have the flay --enable-default-toolkit=gtk2

With both the linux ( slackware)  and the windows when i change to the modern
theme the button does show the colors
