title: Waypoints remove class
body: <p>I am using waypoints.js to handle a single-page site with a highlighted navigation. If the viewport reaches the class "content" the navigation point gets the class "active". The script works fine so far. What I want to achieve is if the <code>.content</code> element leaves the viewport, the class <code>.active</code> should be removed from the navigation point (<code>.content-nav-point</code>).</p>
  
  <pre><code>$('.content').waypoint(function() {
      $( '.content-nav-point' ).toggleClass('active');
  }, { offset: '0%' });
  </code></pre>
