我的导航条代码看起来是 -
<body>
<!--Navbar -->
<nav class="navbar navbar-inverse navbar-fixed-top">
<div class="container-fluid">
<div class="navbar-header">
<a class="navbar-brand" href="#" style="color: #FFFFFF;">TALENTMATCH</a>
</div>
<div class="collapse navbar-collapse" id="navbarHeaderCollapse" style="font-size: 13px;">
<ul class="nav navbar-nav navbar-right">
<li><a href="/jobs">JOBS</a></li>
{% if current_user.is_authenticated() %}
<li><a href="/profile">PROFILE</a></li>
{% else %}
<li><a href="/login">SIGN IN</a></li>
{% endif %}
</ul>
</div>
</div>
</nav>
但是nabber在移动设备上或者缩小浏览器大小时不会崩溃。它只是消失了。我在某个地方看到这可能是因为我可能没有正确设置视口的元标记,但我有 -
<html lang="en">
<head>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
如何调试此问题?

我认为您在显示切换按钮的导航栏标题中缺少以下声明:
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse"
data-target="#navbarHeaderCollapse">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
...
</div>
