title: Highlighting the element after scrolling to it
body: <p>Here is the fiddle I'm working with: <a href="http://jsfiddle.net/fz5Yk/5/" rel="nofollow">http://jsfiddle.net/fz5Yk/5/</a></p>
  
  <p>As you can see, it has a one-page scrolling navigation. I want to achieve a highlighting effect (preferably using .animate function) to the headings in <code>&lt;strong&gt; &lt;/strong&gt;</code> tags when scrolling to a section. Just scroll the page manually and you will see a highlighting in the navigation menu; item of the scrolled section, but I can't quite resolve the js codes in order to apply the same to the headings, and an intervention in it with .animate function seems much more difficult to me. Can you help me?</p>
