答案 0 :(得分：1)
我相信这是你要做的。
您可以在单个.navbar-fixed-top中包含两个单独的导航栏，以便在样式差异的同时保持各个类，同时保持固定位置且不重叠：navbar-default和navbar-inverse。然后确保每个都有自己唯一的data-target，以便各个切换功能正常运行。
例如：
data-target="#navbar1" with id="navbar1"
data-target="#navbar2" with id="navbar2"
此外，您应该使用navbar-right类而不是pull-right。有关详细信息，请参阅Navbar Alignment。
工作示例：
body {
padding-top: 110px;
}
div.navbar {
margin-bottom: 0;
}<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet" />

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has
survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing
