基本上我的问题是，如果导航栏折叠(小窗口)并且无法发现错误，我将无法打开它。
我要的是这个http://getbootstrap.com/examples/navbar-fixed-top/

实际上我对下拉菜单有同样的问题，这可能是相关的。据我所知，在服务器端，我使用 Typo 3 6.2 限制了我复制所有内容。会不会是版本问题，或者我是否过度锁定了某些东西。
到目前为止我已经检查过:
我是 Stack Overflow 的新手，如果我仍然遗漏任何问题，请随时询问。
谢谢大家。 :)
最佳答案
页面上有 javascript 错误:
Uncaught Error: Bootstrap's JavaScript requires jQuery version 1.9.1 or higher, but lower than version 4
要修复它，您应该使用 jQuery 1.9.1 或更高版本。或者只使用 CDN:
<script src="https://code.jquery.com/jquery-1.9.1.min.js" type="text/javascript"></script>
<script src="./TITE_ Home_files/bootstrap.min.js.download" type="text/javascript"></script>
关于html - Bootstraps Navbar 问题，无法打开，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/41420222/
