Question

我使用Bootstrap创建了此页面。当我将页面拖动到更窄的尺寸时，Navbar会消失并被替换为按钮。这个按钮的想法是，一旦点击它就会打开导航选项。最后一点没有发生，我似乎无法找到解决方案。我已经滚动网络多年没有成功。请帮忙。

最明显的事情是你有一个名为js的文件夹，其中包含bootstrap min js并且名为bootstrap.min.js，因为你从CDN调用jQuery，你需要有一个活动连接到网络，而不是仅仅从本地服务器工作。

您还需要在导航栏折叠上放置一个ID并将其作为按钮的目标，因为页面中有多个项目，其中包含＆＃34; navbar＆＃34;的类别。

如下：

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <!-- The above 3 meta tags *must* come first in the head; any other head content must come *after* these tags -->

    <title>Grid System 3</title>

    <!-- Bootstrap -->
    <link href="css/bootstrap.min.css" rel="stylesheet">

    <!-- HTML5 shim and Respond.js for IE8 support of HTML5 elements and media queries -->
    <!-- WARNING: Respond.js doesn't work if you view the page via file:// -->
    <!--[if lt IE 9]>

        border: 1px solid grey;
        background-color: #D3D3D3;
      }

    </style>

  </head>
  <body>

    <div class="navbar navbar-inverse">

      <div class="container">

        <div class="navbar-header">
          <a href="" class="navbar-brand">My Website</a>

          <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#navbar">

          <span class="sr-only">Toggle navigation</span>

          <span class="icon-bar"></span>
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>

          </button>

        </div>
        <div id="navbar" class="navbar-collapse collapse">  


          <ul class="nav navbar-nav">
            <li><a href="">Page 1</a></li>
            <li><a href="">Page 2</a></li>
            <li><a href="">Page 3</a></li>
          </ul>

    <h1>Hello, world!</h1>

    <div class="container">

      <div class="row">
        <div class="col-md-4 box">.col-md-4</div>

        <div class="col-md-4 box">.col-md-4</div>

我已经测试了它，它按预期工作。

引导按钮切换不会打开LI
