As of April 2026, Thematic html5 plugin is a WordPress HTML5 plugin with 20 active installations and a 0/5 rating0. It has been downloaded 3.3K+ times in total. Requires WordPress 3.4+ and PHP false+. Available on WordPress.org since 2012. Last updated 13 years ago — may have compatibility concerns. Top alternative: Easy Video Player.
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 html><html> tag<head>| WordPress | 3.4+ requiredTested up to 3.5.2 |
| PHP | false+ required |
