--------------------------+-----------------------------
 Using latest version of WordPress & Blocksy theme with very few
 modifications or plugins. I notified Blocksy of an invalid HTML detected
 by validator.w3.org and the theme developers say that the WordPress core
 is actually the cause, not the theme.

 Here is the code that produces invalid HTML at w3.org:

 {{{
 <style>.wp-container-1 .alignleft { float: left; margin-right: 2em; }.wp-
 container-1 .alignright { float: right; margin-left: 2em; }</style>
 <style>.wp-container-2 .alignleft { float: left; margin-right: 2em; }.wp-
 container-2 .alignright { float: right; margin-left: 2em; }</style>
 <style>.wp-container-3 .alignleft { float: left; margin-right: 2em; }.wp-
 container-3 .alignright { float: right; margin-left: 2em; }</style>
 }}}
