twitter bootstrap 3 - Bootstrap3 : navbar-fixed-bottom conditionnaly hide depending on content lenght -

i have bottom navbar sticking bottom of page when shown next behaviour:

* shown: 1. when page content height smaller page height 2. when bottom of page reached * hiddden: when page content long enough, i.e. fills more page height , page bottom not reached

i using bootstrap3 , css class navbar-fixed-bottom, navbar visible. hidden when content long enough.

<div class="content"> content goes here, length varies depending on page </div> <footer> <div class="navbar navbar-inverse navbar-fixed-bottom"> <div class="container"> <div class="navbar-collapse collapse" id="footer-body"> <ul class="nav navbar-nav"> <li><a href=“#">link one</a></li> <li><a href=“#">link two</a></li> <li><a href=“#">link three</a></li> </ul> <ul class="nav nav-pills pull-right"> <li class="copyright"></li> </ul> </div> <div class="navbar-header"> <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#footer-body"> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </button> </div> </div> </div> </footer>

use jquery, alter 100 desired character limit.

$(document).ready(function() { var len = $('.content').text().length; if(len > 100){ $('footer').addclass('hidden'); } });
