请问问题是什么。以下是实际网站：https://ebereorisi.github.io

Answer 1

您需要在html中的某处包含bootstrap javascript才能使其正常工作：

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js"></script>

我将它添加到控制台（在您的网站上），如下所示：

var script = document.createElement('script');
script.type = 'text/javascript';
script.src = 'https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js';
document.head.appendChild(script);

并且有效。

导航栏切换按钮依赖于bootstrap javascript工作，因此在您的html文档中，您需要将其包含在页面底部，不要忘记包含Jquery

<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js"></script>
