Question

我正在尝试为移动屏幕制作可折叠的导航栏。它确实崩溃并显示图标栏跨度标记;但是，当我点击它时它什么也没做。

这是我的HTML：

    </div>
</div>

</body>

我似乎无法弄明白。

您缺少元标记：

<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 -->

特别是视口对于bootstrap正常工作至关重要。

你也没有实现jQuery。在body标签的底部添加以下内容：

<!-- jQuery (necessary for Bootstrap's JavaScript plugins) -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<!-- Include all compiled plugins (below), or include individual files as needed -->
<script src="js/bootstrap.min.js"></script>

添加元标记和脚本标记后，这应该是您的代码：

<html lang="en">
<head>
  <meta charset="utf-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
