格式化引导导航栏

使用Bootstrap 3,你几乎可以完成你想做的一切 responsive utilities . 正在添加 .visible-* 和 .hidden-*

<nav class="navbar navbar-default">
  <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-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="#">Brand</a>
      <div class="pull-right visible-xs hidden-sm hidden-md hidden-lg">
          <i class="fa fa-search"></i>
    </div>
    </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 hidden-sm hidden-md hidden-lg">
        <li><a href="#">Submenu</a></li>
        <li><a href="#">Submenu</a></li>
        <li><a href="#">Submenu</a></li>
        <li><a href="#">Sair</a></li>
      </ul>

      <ul class="nav navbar-nav navbar-right">
        <li class="visible-sm visible-md visible-lg"><i class="fa fa-search"></i></li>
        <li class="dropdown visible-sm visible-md visible-lg">
          <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Nome do Usuario <span class="caret"></span></a>
          <ul class="dropdown-menu">
            <li><a href="#">Submenu</a></li>
            <li><a href="#">Submenu</a></li>
            <li><a href="#">Submenu</a></li>
            <li role="separator" class="divider"></li>
            <li><a href="#">Sair</a></li>
          </ul>
        </li>
      </ul>
    </div><!-- /.navbar-collapse -->
  </div><!-- /.container-fluid -->
</nav>
