Nice Image, some great advice, I would like to have it as my desktop background but...
Doctype Transitional.
<img> tag without width and height.
<div style="clear: both;"></div> ?
This isn't HTML code -- this is PHP code.
It's all HTML except for a couple of server-side includes that happen to use PHP to include HTML. In any case it's definitely a better example of HTML code than of PHP code :)
