我正在使用 bootstrap 3 制作一个响应式网站。折叠的导航栏存在问题，它不是正常高度(即一个导航链接项的高度)，而是占据了所有导航链接项的总高度.这是我正在谈论的内容的屏幕截图http://tinyurl.com/pr4hae5
这是我的 HTML，我没有覆盖任何默认的 Bootstrap CSS。

这很好用... 刚刚将您的导航栏添加到 starter template 并改变了:
<nav class="navbar navbar-inverse">
进入
<nav class="navbar navbar-inverse navbar-fixed-top">
我认为您忘记了代码中的 javascript:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="http://getbootstrap.com/dist/js/bootstrap.min.js"></script>
在 getbootstrap.com 上
Requires JavaScript plugin If JavaScript is disabled and the viewport is narrow enough that the navbar collapses, it will be impossible to expand the navbar and view the content within the .navbar-collapse.
The responsive navbar requires the collapse plugin to be included in your version of Bootstrap.
