title: hover for 2 seconds fadeIn/out sibling not working
body: <p>I manage to get hovering for 2 seconds to fadeIn/Out on a ID or a Class (which catches all with the same class obviously), but i can't get this working on a (this).sibling("className")</p>
  
  <p>Also the fadeIn/Out or toggleFade works fine without the if statement... I have run out of ideas to get hovering for more than 2 seconds before make a sibling element fadeIn</p>
