I am a newbies to bootstrap. I have tried to play with the code to make a page with toggleable tag. However, I have checked my code for many times but I still can't find the problem in my code. Would anyone help me, please? <div class="row"> <div class="tabbable"> <ul class="nav nav-tabs" id="tabs" data-tabs="tabs"> <li class="active"><a href="#having_a" data-toggle="tab">Having a</a></li> <li><a href="#having_b" data-toggle="tab">Having b</a></li> <li><a href="#having_c" data-toggle="tab">Having c</a></li> </ul> <!-- content of the tab --> <div class="tab-content" id="tab-content"> <div class="tab-pane active" id="having_a"> <p>a</p> </div> <div class="tab-pane" id="having_b"> <p>b</p> </div> <div class="tab-pane" id="having_c"> <p>c</p> </div> </div> </div> <script type="text/javascript"> jQuery(document).ready(function ($) {$('#tabs').tab(); }); </script> </div> <hr> <footer> <p>&copy;2012</p> </footer> </div> <!-- /container --> <!-- Le javascript ================================================== --> <!-- Placed at the end of the document so the pages load faster --> <script src="js/jquery.js"></script> <script src="js/bootstrap-transition.js"></script> <script src="js/bootstrap-alert.js"></script> <script src="js/bootstrap-modal.js"></script> <script src="js/bootstrap-dropdown.js"></script> <script src="js/bootstrap-scrollspy.js"></script> <script src="js/bootstrap-tab.js"></script> <script src="js/bootstrap-tooltip.js"></script> <script src="js/bootstrap-popover.js"></script> <script src="js/bootstrap-button.js"></script> <script src="js/bootstrap-collapse.js"></script> <script src="js/bootstrap-carousel.js"></script>
