Started validating this theme at http://d-theme.com/antique_modern. The following line has a block level element, ul, inside an inline element, span. Change the span to a div.
<span class="taxonomy"><ul class="links inline"><li class="taxonomy_term_32 first last"><a href="/taxonomy/term/32" rel="tag" title="">a</a></li>

The theme is short one closing div. I looked at the page but did not see anything obvious.

Validating the CSS as 2.1 and 3 produced the following errors for both levels.

URI : http://d-theme.com/sites/all/themes/antique_modern/style.css?n

Thoughts on changing those padding values to margin?
