我目前正在制作乐队页面，但导航栏存在问题。我希望导航栏为黑色以匹配乐队的 Logo ，但尽管在我的 css 页面上尝试了所有相关类，但似乎无法更改背景颜色。
<nav class="navbar navbar-default">
<div class="container">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="index_thekatellas.html">
<img src="katellas.jpg">
</a>
</div>
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav navbar-left">
<li><a href="tour_thekatellas.html">Tour Dates</a></li>
<li><a href="band_thekatellas.html">Band</a></li>
<li><a href="music_thekatellas.html">Music</a></li>
</ul>
</nav>
最佳答案
你应该使用
<nav class="navbar navbar-inverse">
它会让你的导航栏看起来是黑色的。
默认为白色，因此反色为黑色。
