24-导航条（网页顶部菜单）

一般用在后台管理系统中比较多。我们这里挑一个出来说，我们的导航条往往用在网址的顶部作为菜单栏。

<nav class="navbar navbar-default navbar-static-top"> 
  <div class="container"> ... </div> 
</nav>Code language: HTML, XML (xml)

这一个就不要放在container里面了，比如我们的菜单栏：

<nav class="navbar navbar-inverse">
  <div class="container-fluid">
    <!-- 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-9" 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="#">FoxDevelop</a>
    </div>

    <!-- Collect the nav links, forms, and other content for toggling -->
    <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-9">
      <ul class="nav navbar-nav">
        <li class="active"><a href="#">首页</a></li>
        <li><a href="#">课程</a></li>
        <li><a href="#">下载</a></li>
      </ul>
    </div><!-- /.navbar-collapse -->
  </div><!-- /.container-fluid -->
</nav>Code language: HTML, XML (xml)
