XHTML as application/xhtml+xml

[Maujor]

Hello,
I'd like to use the Mathias code: XHTML content negotiation through PHP for serve my XHTML 1.1 pages.
All works fine, but the body background imagem (simulates shadows and background-colors for navigations columns) stops extends along y-axis when align whith the bottom of the header. This happens only when MIME is application/xhtml+xml (compliant browsers).
Well, I hosted a test page at:

If you see it in IE all is OK, but in Firefox you'll notice the lost background.
And here the document served as text/html for good browsers: http://www.maujor.com/index.php Link removed - xhtmlcoder point out the solution!
Thanks for any welcome help

Remember with application/xhtml+xml the root is html thus apply the image to html rather than body. For example: html { background-image:url('image.png');}

See MIME Test — CSS body Element Test:

When served as text/html, the body element fills the whole viewport, whereas the html element fills the viewport when served as application/xhtml+xml.

You’re welcome! Hell, I just wanted to point out that your problem wasn’t caused by my script!

Yes Mathias I know.
I didn't realize that the XML root was the html element.
Your script is great
And is great too the #infobar of your site.
I'm using your CSS code for that IE effect, and sending my visitors to "Browser Happy".
