Sample page showing the problem described.

Sample page that shows the correct rendering.
757 bytes, text/html
Details 
User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3a) Gecko/20021212
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3a) Gecko/20021212

Depending on the document type declaration etc. (see below) of an XHTML 1.1
page, Mozilla does not render the page's background colour correctly. Precisely,
the background colour does not fill the page's margin, and in the case of a page
that takes up only part of one screen, the background colour only extends to the
end of the page's contents instead of to the bottom of the browser window, too.

This happens in the case of an XHTML page contained in an XML file, sent with
Content-Type: text/xml and beginning thusly:

<?xml version="1.0"?>  
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"
"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

On the other hand, a HTML file, sent as Content-Type: text/html and beginning as
follows will work:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"
"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html>

This has been confirmed with Mozilla 1.3a (1.3b is, unfortunately, too unstable
for me to use).

Reproducible: Always

Steps to Reproduce:
1. Load http://gl00on.net/moz1.xml

Actual Results:  
See above.

Expected Results:  
See http://gl00on.net/moz1a.html for the expected results.

    
    

    
  


  

    
    

    
  
As an additional note, both pages are valid XHTML 1.1 according to the W3C's
validator service.

This is the proper rendering. As an XML doc the body is simply a block element
inside the html element. As such its affected by margins & padding, etc. & the
hieght of the viewport has no impact on its height.

the bug is invalid, but i'm sure there's a bug with a better explanation to dupe
this to...

    
    

    
  
Thanks for your help, Chris. What would be the proper way to ensure that the XML
document is rendered the same way as the HTML variant?

    
    

    
  
In short, style the <html> element, not <body>.  See bug 147856 and bug 90356
for more info.

Just as a general note, remember that anything served as text/html is processed
as HTML, even if it really is XHTML (the file type has precedence).  This can
cause some interesting, although completely correct, behavior.
