title: Creating a Sliding Indicator Under the Main Navigation when User Scrolls
body: <p>I was wondering if it was possible to create an indicator that moved across the bottom of the main navigation as the user scrolls down the page. <a href="http://imgur.com/6CQfa.jpg" rel="nofollow">Here</a> is an image of what I hope to make my main navigation look like.</p>
  
  <p>The goal would be to have the tabbed part move as the user scrolls to different sections of the page.</p>
  
  <p>Is this possible? And if so, can you point me in the direction of a tutorial or jquery plugin? 
  Thanks for your time.</p>
