Valid without warning
Tarski theme is really good. You see, the theme is basically XHTML 1.1 valid (with little modification – the mime type (set to application/xhtml+xml), doctype (set to XHTML 1.1), and manually set <html> attributes).
The problem is: AdSense and reCAPTCHA is gone o_o
Gotta check the source of the problem. Returning back to XHTML 1.0 Strict for now…
Update: most likely found the source of the problem. It’s unfixable though as the js is not on my site. [ Info ]
Royale 1.4 used by Hemisphere (Mou Yamete site) is very nice, too..
