im not sure who manages the website.
and this is prolly something for your all mighty and secluded core section.
but the site fails both w3c's XHTML and CSS validations.
the CSS should be an easy fix
line 37 of the style sheet
"Unrecognized link element or xml-stylesheet PI. "
the xhtml has a bit more too it
its mostly a lack of end tags and xml parsing errors.
you can change the validation level without changing the code to fix the end tags issues or add the end tags. and im not sure about all the xml stuff.
but more importantly... does anyone care?
if it wasnt a pretty button i prolly wouldnt have clicked it
