Bootstrap3-导航条

1. 定义导航条

<!-- 导航条 navbar -->
<div class="navbar nav-bar-default">
  <ul class="nav nav-pills">
  	<li class="active"><a href="#">首页</a></li>
  	<li><a href="#">登录</a></li>
  	<li><a href="#">退出</a></li>
  </ul>
</div>

添加网站表示名(navbar-brand)

<div class="navbar nav-bar-default">
  <a href="#" class="navbar-brand">伊人考试系统</a>
  <ul class="nav nav-pills">
  	<li class="active"><a href="#">首页</a></li>
  	<li><a href="#">登录</a></li>
  	<li><a href="#">退出</a></li>
  </ul>
</div>

导航条包括链接、下拉菜单、网站标题和折叠按钮

<nav class="navbar navbar-default" role="navigation">
    <div class="navbar-header">
     <button class="navbar-toggle" type="button" data-toggle="collapse" data-target="#menu">
          <span class="sr-only">展开导航</span>
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>
       </button>
       <a href="#" class="navbar-brand">网站标题</a>
    </div>
   <div class="collapse navbar-collapse" id="menu">
      <ul class="nav navbar-nav">
         <li><a href="#">首页</a></li>
         <li><a href="#">导航标题1</a></li>
         <li><a href="#">导航标题2</a></li>
         <li class="dropdown">
           <a href="#" class="dropdown-toggle" data-toggle="dropdown">
              下拉菜单<b class="caret"></b>
           </a>
           <ul class="dropdown-menu">
              <li><a href="#">下拉菜单1</a></li>
              <li class="divider"></li>
              <li><a href="#">下拉菜单2</a></li>
              <li class="divider"></li>
           </ul>
        </li>
      </ul>
   </div>
 </nav>

2. 绑定对象

包裹菜单

<!-- 导航条 包裹表单 -->
 <nav class="navbar navbar-default" role="navigation">
       <a href="#" class="navbar-brand">网站标题</a>
   <form action="" class="navbar-form navbar-left" role="search">
      <div class="form-group"><input type="text" class="form-control" placeholder="关键字"></div>
      <button class="btn btn-default" type="submit">提交</button>
   </form>
 </nav>

包裹下拉菜单

 <!-- 导航条 包裹下拉菜单 -->
 <div class="navbar navbar-default">
    <ul class="nav navbar-nav">
       <li class="dropdown">
           <a href="#" data-toggle="dropdown">分享 <b class="caret"></b></a>
           <ul class="dropdown-menu">
              <li><a href="#">QQ</a></li>
              <li><a href="#">微信</a></li>
              <li><a href="#">微博</a></li>
           </ul>
       </li>
    </ul>
 </div>

包裹按钮(navbar-btn类)

<div class="navbar navbar-default">
    <button class="btn btn-default navbar-btn" type="button">按钮1</button>
    <button class="btn btn-primary navbar-btn" type="button">按钮2</button>
    <button class="btn btn-default navbar-btn" type="button">按钮3</button>
 </div>

包裹文本(navbar-text)和链接(navbar-link)

<div class="navbar navbar-default">
     <button class="btn btn-default navbar-btn" type="button">按钮</button>
    <p class="navbar-text">欢迎登录！</p>
    <p class="navbar-text">
        普通段落<a href="#" class="navbar-link">链接</a></p>
 </div>

3. 设计导航条

置顶导航条(.navbar-fixed-top .navbar-static-top)
navbar-fixed-top和navbar-static-top的区别:
fixed会吸附在顶部，static在页面下拉滚动式会消失
