• 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

    1. 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>
    
    1. 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>
    
    1. 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>
    
    1. 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

    1. 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
    <!DOCTYPE html>

       </body>
    </html>
    
    1. 置底导航条(navbar-fixed-bottom)
    <!DOCTYPE html>
    <html>
       <head>
          <title>Bootstrap 导航条</title>
          <meta name="viewport" content="width=device-width, initial-scale=1.0">
