我知道这已被发布了很多次，但我仍然无法找到解决方案。我试过在移动设备上观看它并缩小浏览器但是所有的导航折叠按钮都没有崩溃。＆＃34;我按照其他帖子提供的指导，但没有一个有效。我已将data-target设置为正确的ID，并且我已获取所有脚本。
我的代码：
nav ul li{
width:117px;
}
nav{
box-shadow: 15px 0px 45px #1f2021;
}
.navbar-fixed-top{
position:absolute!important;

为什么你有这么多样式表？似乎引导样式表没有呈现。

你有一些错位的标签。喜欢丢失</div>和</span>。这个有效。
div#navbar.navbar-collapse.collapse.in {
max-height:600px
}
nav{
box-shadow: 15px 0px 45px #1f2021;
