[macs300]

<script>
    $(document).ready(function(){
      // Add smooth scrolling to all links
      $("a").on('click', function(event) {

        // Make sure this.hash has a value before overriding default behavior
        if (this.hash !== "") {
          // Prevent default anchor click behavior
          event.preventDefault();

          // Store hash
          var hash = this.hash;

          // Using jQuery's animate() method to add smooth page scroll
          // The optional number (800) specifies the number of milliseconds it takes to scroll to the specified area
          $('html, body').animate({
            scrollTop: $(hash).offset().top
          }, 800, function(){

            // Add hash (#) to URL when done scrolling (default click behavior)
            window.location.hash = hash;
          });
        } // End if
      });
    });
  </script>
