title: jQuery change css attribute slowly
body: <p>I have this code</p>
  
  <pre><code>$('#uiAdminPanelMenu li a').hover( function(){
      $(this).css('background-color', '#D3E1FA';
   },
   function(){
      $(this).css('background-color', '#F4F4F4');
  });
  </code></pre>
  
  <p>it changes the background color of the link, but I want it to change it slowly, kinda like fade effect, but for this case.</p>
