Make any footer stick to the bottom if there is room below the element. It works on page load and browser resize. Source: http://foundation.zurb.com/forum/posts/629-sticky-footer

stickyfooter.js

 // Make sure you do not put padding on the class/id being used in the JavaScript below
 
$(window).bind('load', function() {
  var footer   = $('footer'),
      position = footer.position(),
      height   = $(window).height();

  height = (height - position.top) - footer.height();

  if (height > 0) {
    footer.css('margin-top', height + 'px');
  }
});
