thanks philip, it is exactly what i wanted.

from a quick review [1] of a sample of pages (where class="header" is
used more than once on a page) of your  sample, the usage of
class="header" appears to bear little relationship to the
specification of the <header> element in HTML5 [2]

it appears to be mainly used  to indicate a heading for styling purposes

<SPAN class=Header>Want to Join?</SPAN>
<table class="header" id="neutral_hmenu">
<table width="100%" class="header" id="neutral">
<table class="header" id="see_also">
<li class="header">
