  * Plugin Name:       Genesis JS / No JS
  * Plugin URI:        https://github.com/GaryJones/genesis-js-no-js
  * Description:       For child themes of the <a href="http://genesis-theme-framework.com/">Genesis Framework</a>. Adds a <code>no-js</code> body class to the front end, and a script on <code>genesis_before</code> which immediately changes the class to <code>js</code> if JavaScript is enabled. This is how WP does things on the back end, to allow differing styles for elements if JavaScript is active or not.
