title: Change css header after scrolling
body: <p>I need some help with my JQuery.</p>
  
  <p>I would like to change the css of the header after scrolling, but can't get it work. The only thing that must change in the css is margin to 65px and delete the logo.</p>
  
  <p><a href="http://jsfiddle.net/jssonline/dJh8w/" rel="noreferrer">Here is the code</a></p>
  
  <pre><code>#menuheader {
  background: -webkit-gradient(linear, center top, center bottom, from(#fff),to(#ccc));
  background-image: linear-gradient(#fff, #ccc);
  box-shadow: 3px 3px 3px 3px #333;
  height: 40px;
  position: relative;
  margin: 165px auto 0;
  z-index: 10;}
  </code></pre>
  
  <p>Many thanks in advance.
  Jason</p>
