我试图让我的导航和页脚链接在宽度减小时折叠成切换按钮，但没有使它们具有类“navbar-default”（该类将另一个导航栏添加到我的导航栏并使它看起来很难看。
以下是我标题导航HTML的示例：
<div class="header" id="header-container">
<div class="container" id="header">
<button class="navbar-toggle collapsed" data-toggle="collapse" data-target="#header-collapse-1"><span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<ul class="nav collapse navbar-collapse nav-pills pull-right" id="header-collapse-1">
<li><a href="/">Home</a></li>
<li><a href="/about">About</a></li>
<li><a href="/img/resume.pdf" target="_blank">Resume</a></li>
<li><a href="/contact">Contact</a></li>
</ul>
<h3>TITLE</h3>
</div>
</div>
导航按钮消失但没有切换按钮可以打开手风琴。如果有解决方法可以显示切换按钮，请告诉我。

我能想到的唯一方法是在导航栏中添加一个类，并创建一些规则来覆盖只有该类的元素的导航栏。
考虑添加这两个规则（并根据需要自定义样式）： -
.custom-nav-bar.navbar-toggle {
background-color: #ddd; /*Background color for holder*/
}
.custom-nav-bar.navbar-toggle .icon-bar {
background-color: #888; /*Background color for bar in the holder*/
}
并将custom-nav-bar添加到navbar-toggle元素
<button class="navbar-toggle collapsed pull-left custom-nav-bar" data-toggle="collapse" data-target="#header-collapse-1">
.custom-nav-bar.navbar-toggle {
background-color: #ddd;
}
.custom-nav-bar.navbar-toggle .icon-bar {
background-color: #888;
}<!DOCTYPE html>
