This plugin will convert the markup of themes based on the Thematic theme framework to use html5 elements. Requires Thematic 1.0 or later. New filters were introduced in Thematic 1.0.2 that optimizes the use of this plugin, but it will work with Thematic 1.0 as well using an output buffer.

It uses the built in filters of Thematic to change the markup in desired places. If you are using any childtheme_override_* functions they will still work, and will override this plugin’s loops as well. You will then need to make sure that your override loops uses html5 yourself.

The markup changes are:

• doctype changed to
• conditional comment classes from html5boilerplate are added to the opening tag
• meta tag “charset” added to
• defunkt meta tag http-equiv=Content-type removed (replaced by meta tag above)
• #header uses
  element
• nav_menu and page_menu uses the
• post pagination links uses the
• nav-above and nav-below uses the
• the loops are using the
  element for individual posts.
• .entry-header uses the
  element
• the post title will always be a

• .entry-utility uses the
• widget areas are
• #footer uses

The plugin will also add a html5shiv javascript so the new elements will work with older IE browsers. It tries to be detect if any other script has been enqueued, like modernizr, and will only add the script if necessary.

The plugin is intentionally very bare bones, no settings or checkboxes, just activate and go. Ideas, bug reports and general feature requests are welcome at the github issue tracker.
