我的Rails 4站点与最新版本的引导不会在手机崩溃，但如果我在桌面上打开网站并缩小窗口，它将崩溃。以下是我的导航栏的代码：
<div class = "navbar navbar-inverse navbar-static-top">
<div class = "container">
<a href = "/" class = "navbar-brand" style="color: white;">Earn And Learn</a>
<button class = "navbar-toggle" data-toggle = "collapse" data-target = ".navHeaderCollapse">
<span class = "icon-bar"></span>
<span class = "icon-bar"></span>
<span class = "icon-bar"></span>
</button>
<div class = "collapse navbar-collapse navHeaderCollapse">
<ul class = "nav navbar-nav navbar-right">
<li id="nav_ach"><a href = "/about/achievements" style="color: white;">Achievements</a></li>
<li id="nav_faq"><a href = "/about/faq" style="color: white;">FAQ</a></li>
<li id="nav_test"><a href = "/about/testimonials" style="color: white;">Testimonials</a></li>
<li id="nav_news"><a href = "/about/news" style="color: white;">In the News</a></li>
<li id="nav_steal"><a href = "/steal/index" style=" color: white;">Steal This Idea!</a></li>
<li><a href = "#" data-toggle="modal" data-target="#myModal" style="color: white;">Contact Us</a></li>
</ul>
</div>
</div>
</div>
解决方法
通过github问题挖掘，结果我们错过了这一点
