如何更改导航栏的默认背景颜色?在我的HTML中我有这个代码,但页面没有渲染这个,它坚持默认的bootstrap css。这是我的实时测试页面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测试页面。我google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">

  <span class="icon-bar"></span>
  <span class="icon-bar"></span>
  </button>
  </div>
  <div class="collapse navbar-collapse navHeaderCollapse">

        <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>                 

        </ul>


        </li>
      </ul>
    </div>

</div></div>

您实际上并未在HTML中的任何位置应用navbar-custom类。使用类div将其添加到navbar上的班级列表的末尾。

<div class="navbar navbar-inverse navbar-fixed-top navbar-custom">

无需更改课程。 只需要让你的选择器具有比现在更高的特异性&#34;支配&#34;之一:

.navbar.navbar-inverse {
background-color: #CC0000;
}

这将取代标准背景。

编辑:如果由于任何原因您更喜欢使用navbar-custom,您必须将此类添加到元素中,并且STILL会使您的选择器具有更高的特异性。 E.g:

.navbar.navbar-custom { }
