A lightweight jQuery plugin to focus and unfocus like a camera. Perfect for full width parallax sites.
Include the javascript and call it on any event, like window load, Waypoints or Unveil with $('#id-of-the-containing-div').refocus();. Add the class focus-in to the elements you want to go from blurry to sharp, and focus-out that you want to go from sharp to blurry.
Include refocus.css and make changes in your own css-file or inline css.
