[jQuery] :not and :headers

[Jon Atkinson]

Hello,

I'm trying to apply a font style to all elements on a page apart from
headers. This is the code I'm using:

    $('*:not(:header)').css('font-family', '\'Trebuchet MS\', Arial,
sans-serif');

This seems to apply the new CSS to all elements on the page. What am I
doing wrong?

Thanks.
