首先 导航栏少东西  

<nav class="navbar navbar-default navbar-fixed-top navbar-inverse" id="menu-nav">

 <div class="container">

<!-- Brand and toggle get grouped for better mobile display -->

<div class="navbar-header">

 <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">

<span class="sr-only">Toggle navigation</span>

<span class="icon-bar"></span>

<span class="icon-bar"></span>

<span class="icon-bar"></span>

 </button>

 <a class="navbar-brand" href="#">现代浏览器博物馆</a>

</div>


<!-- Collect the nav links, forms, and other content for toggling -->

<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">

 <ul class="nav navbar-nav">

<li class="active"><a href="#">综述</a></li>

<li><a href="#">简述</a></li>

<li class="dropdown">

 <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">特点 <span class="caret"></span></a>

 <ul class="dropdown-menu">

<li><a href="#tab-chrome" data-tab="tab-chrome">Chrome</a></li>

<li><a href="#tab-firefox" data-tab="tab-firefox">Firefox</a></li>

<li><a href="#tab-safari" data-tab="tab-safari">Safari</a></li>

<li><a href="#tab-opera" data-tab="tab-opera">Opera</a></li>

<li><a href="#tab-ie" data-tab="tab-ie">IE</a></li>

 </ul>

</li>

<li><a href="#" data-toggle="modal" data-target="#about-modal">关于</a></li>

 </ul>

</div><!-- /.navbar-collapse -->

 </div><!-- /.container-fluid -->

</nav>
