我正在构建应在所有设备上响应的单页应用程序。到目前为止一切正常，但有一件事引起了我的注意。当 lg 和 md 屏幕尺寸时，主屏幕上的选项卡会水平显示。如果我在浏览器中打开 响应式设计模式，它们会垂直显示。该演示文稿在屏幕上占用了大量空间。我想知道它们是否可以显示为可折叠按钮，用户可以在其中单击并选择选项卡？这会在屏幕上节省一些空间，而且看起来肯定更好看。这是我目前所拥有的示例:
.navbar-brand {
padding: 0px;
}
.navbar-brand>img {
height: 100%;
min-height: 45px;
padding: 5px;
width: auto;
}
.brand2 {
height: 100%;
height: 50px;
padding: 5px;
margin-left: 5px;
width: auto;
display: block;
}
.my-jumbotron {
padding-top: 45px;
padding-bottom: 10px;
margin-bottom: 5px;
background-color: #333;
color: #fff;
}
.page-footer {
margin-bottom: 5px;
background-color: #333;
border-radius: 6px;
padding: 5px;
color: #fff;

</html>如果您检查上面的示例，您会看到选项卡彼此重叠。如果您查看右上角，您会看到可以单击的按钮。然后您将在菜单 Home、Contact 或 Help 中获得元素列表。我想为小屏幕上的选项卡提供类似的东西。如果有人知道实现该目标的好方法，请告诉我。
最佳答案
希望这会有所帮助。我把你的导航标签做了个 fiddle
https://jsfiddle.net/nk7wp0m8/4/
@media only screen and (max-width:800px) {
.nav-tabs.nav-justified>li {
float: left;
width: 25%;
}
}
如果您要确定您的页面让它们开始堆叠的宽度，那么您可以使用上述媒体查询并强制它们全部并排显示。

这个 fiddle 给你一个显示，比如你的家、联系人等的导航。
