text: Q:
  
  .append and fade in
  
  I append a div with a overlay effect like this:
  $("body").append('<div class="overlay-white"><div>')
  
  The overlay-white class. Have this css:
  position                : absolute;
      top                     : 0;
      left                    : 0;
      width                   : 100%;
      height                  : 100%;
      z-index                 : 500;
      background              : url(../img/backgrounds/bg-overlay.png) repeat left top;
  
  But now my problem. The overlay pops it now. But how can i fade in the overlay??? 
  
  A:
  
  var overlay = $('<div class="overlay-white"><div>');
  overlay.hide().appendTo("body").fadeIn();
