Answer 1

在关闭 head 标签之前使用它

    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link rel="stylesheet" type="text/css" href="css/bootstrap.min.css">
    <link rel="stylesheet" type="text/css" href="css/bootstrap-responsive.min.css">

然后是html部分

    <div class="navbar navbar-inverse"> 
        <div class="navbar-inner">  
        <div class="container">   
         <a class="btn btn-navbar" data-toggle="collapse" data-target=".navbar-inverse-collapse">
          <span class="icon-bar"> </span>
          <span class="icon-bar"> </span>
          <span class="icon-bar"> </span>
        </a>   
     <a href="pages/" class="brand"> Expense Manager</a>

      <div class="nav-collapse collapse navbar-inverse-collapse">  
            <ul class="nav ">   
                <li class="dropdown ">  <a href="users" class="dropdown-toggle" data-toggle="dropdown"> Users <i class="caret"> </i> </a>
                    <ul class="dropdown-menu mydropdown">   
                        <li> <a href="users/add" class="linkmain"> Add Users </a> </li>
                        <li> <a href="users/" class="linkmain"> Manage Users </a> </li>
                    </ul>  
                </li>
                <li class="dropdown "><a href="users" class="dropdown-toggle" data-toggle="dropdown"> Users <i class="caret"> </i> </a>
                    <ul class="dropdown-menu mydropdown">   
                        <li> <a href="users/add" class="linkmain"> Add Notes </a> </li>
                        <li> <a href="users/" class="linkmain"> Manage Notes </a> </li>
                    </ul> 
                </li>
            </ul>  
            <ul class="nav pull-right">   
                <li class="active"> <a href="users/login"> Login to add your expense </a></li>
            </ul>   
     </div>
    </div> 
</div>
</div>
