html - 为什么我的 Bootstrap 导航栏不会崩溃？

Question

我正在尝试编写我团队网站的代码。导航栏不会在移动屏幕上折叠。我添加了“数据目标”来定位列表中的类。单击该按钮时，列表应该折叠，但实际上并没有。

<!-- Navbar -->

<div class="navbar navbar-inverse navbar-fixed-top" role="navigation">
    <div class="container">
        <div class="navbar-header">
            <a class="navbar-brand" href="/Home">Team 3774</a>
        </div>
        <div class="navbar-header">
      <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navHeaderCollapse">
        <span class="sr-only">Toggle navigation</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
    </div>
        <div class="collapse navbar-collapse navHeaderCollapse" style="height: 0.866667px;">
            <ul class="nav navbar-nav">
                <li><a href="/Team Bio">Team Bio</a></li>
                <li><a href="/Our Coach">Our Coach</a></li>
                <li><a href="/Gallery">Gallery</a></li>
                <li><a href="/Outreach">Outreach</a></li>
                <li><a href="/Youtube">Youtube</a></li>
            </ul>
        </div>
    </div>
</div>

试试这个:

<div class="navbar navbar-inverse navbar-fixed-top" role="banner">

            <span class="sr-only">Toggle navigation</span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
