screenshots:

the next screenshots shown when navbar alternative clicked page go right div, will not scroll. help resolving great.

after bit more research , using great example:http://alijafarian.com/responsive-page-scrolling-with-jquery-and-bootstrap/ managed produce solution below works perfectly.

<script> $(document).ready(function() { $('#nav .navbar-nav li>a').on('click', function(event){ event.preventdefault(); var sectionid = $(this).attr("href"); scrolltoid(sectionid, 750); }); function scrolltoid(id, speed) { var offset = 70; var targetoffset = $(id).offset().top - offset; $('html,body').animate({scrolltop:targetoffset}, speed); } }); </script>
