看来我拥有了正确的地方。Bootstrap导航栏不会在智能手机上崩溃
在头上。没有视meta标签（我试过，但没有运气）
<title>My Title for Webpage</title>
<link href="css/bootstrap.min.css" rel="stylesheet" />
右键关闭标签
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script src="js/bootstrap.min.js"></script>
</body>
这上面是导航栏HTML
