Javascript to Add smooth scrolling to all links

<!--<script>-->
<!--$(document).ready(function(){-->
  // Add smooth scrolling to all links
<!--  $(".nav-tabs 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-->
<!--      }, 2000, function(){-->
 
        // Add hash (#) to URL when done scrolling (default click behavior)
<!--        window.location.hash = hash;-->
<!--      });-->
    } // End if
<!--  });-->

<!--});-->
<!--</script>-->
