我已经让这个导航栏在我的登陆页面上工作，我希望它在第二页上看起来也一样，但它没有显示。我不确定我做错了什么，因为我只是从第一页复制/粘贴。

这可能只是遗漏了一些小东西，但我已经盯着它看了一会儿，似乎无法弄清楚。

这是我的第二个页面的代码，它不会显示在上面。

最佳答案

尝试改变:

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.0/css/bootstrap.min.css">

到:

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.3.1/css/bootstrap.min.css">

可能是您使用的是错误的过时版本/链接
