如何更改导航栏的默认背景颜色？在我的 html 中，我有这段代码，但页面没有呈现它，它坚持使用默认的 Bootstrap css。这是我的现场测试页面http://andrewsamonas.com/它显示默认的反向暗导航栏而不是我的导航栏自定义导航栏。我在谷歌上搜索了很多，这就是我发现使用 navbar-custom 的方式
这是我添加到我的 style.css 中的内容:
.navbar-custom {
background-color: #CC0000;
border-color: #AA0000;
border-radius: 0;
}
.navbar-custom .navbar-brand,
.navbar-custom .navbar-brand:hover,
.navbar-custom .navbar-brand:focus {
color: #FFF;
}
.navbar-custom .navbar-nav > li > a {
color: #FFF;
}
.navbar-custom .navbar-nav > li > a:hover,
.navbar-custom .navbar-nav > li > a:focus {
background-color: #AA0000;
}
.navbar-custom .navbar-nav > .active > a,
.navbar-custom .navbar-nav > .active > a:hover,
.navbar-custom .navbar-nav > .active > a:focus {
color: #FFF;
background-color: #AA0000;
}
.navbar-custom .navbar-text {
color: #FFF;
}
.navbar-custom .navbar-toggle {
border-color: #AA0000;
}
.navbar-custom .navbar-toggle:hover,
.navbar-custom .navbar-toggle:focus {
background-color: #AA0000;
}
.navbar-custom .navbar-toggle .icon-bar {
background-color: #FFF;
}
this is in the html head <link rel="stylesheet" href="css/styles.css">

this is the navbar part
<div class="navbar navbar-inverse navbar-fixed-top">
<div class="container">
<div class="navbar-header">
<a href="#" class="navbar-brand">My Site</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>
<div class="collapse navbar-collapse navHeaderCollapse">
<ul class="nav navbar-nav navbar-right">
<li><a href="#">Home</a></li>
<li><a href="#">About</a></li>
<li><a href="#">Contacts</a></li>
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown">Login<b class="caret"></b></a>
<ul class="dropdown-menu">
<li><a href="#">Logout</a></li>
<li><a href="#">Logout</a></li>
<li><a href="#">Logout</a></li>
</ul>
</li>
</ul>
</div>
</div></div>
<div id="push"></div>最佳答案
实际上您还没有在 HTML 中的任何地方应用 navbar-custom 类。将它添加到 div 类列表的末尾，类 navbar。
<div class="navbar navbar-inverse navbar-fixed-top navbar-custom">
