title: backgroundColor does not animate, but width does in jQuery
body: <p>I want the color of my div.navBtn elements to change through an animation effect. It isn't working out and I don't know why.</p>
  
  <pre><code>$(document).ready(function()
  {
    $("button").click(function()
    {
      $("div.navBtn").animate(
      {
        width:'+=10px',
        backgroundColor: "#aa0000"
      });
    });
  });
  </code></pre>
  
  <p><code>backgroundColor</code> is what does the actual color changing but it does not work. Width <code>+=10</code> works perfectly, backgroundColor does absolutely nothing. Is the syntax wrong or something??? I copied <code>"backgroundColor: "#aa0000""</code> from another help posting here. Does anyone know what the problem is?</p>
