While using a top level css-file for designing a web page, i've noticed that
firefox interprets a url given for the background as a relativ path to the html
file and not to the css file as it should be.


Reproducible: Always

Steps to Reproduce:
1. Create a html file (test.htm) in a directory "html"
2. Create a css file  (eg. style.css) in a directory "css"
3. copy a background image to the css directory
4. add the following line to the css file
body { background-image:url(header.jpg); margin:0px; padding-left:10px;
padding-top:66px; background-repeat:no-repeat; }
5. add <link rel="stylesheet" type="text/css" href="../css/style.css" /> to the
html file
Actual Results:  
IE shows the correct background image; Firefox doesn't

Expected Results:  
A background image.



When you replace url(header.jpg) with url(../css/header.jpg) you get the
backgroundimage with firefox but not with IE.

But in this case there is no more benefit from a global css-File because when
there is an directory in the html directory eg. html/samples/ ypu cannot use
the css file because you can either write
url(../css/header.jpg) or
url(../../css/header.jpg)

So in my opinion the background-image information has to be relative to the css file

Please recheck this bug against a recent nightly build[1] to verify that the
behavior still exists and post the results here.

Also, please supply a testcase to help others verify this behavior.

Thanks.
