也试试这个。这对我很管用。

.navbar-default .navbar-nav > li > a:hover,
.navbar-default .navbar-nav > li > a:focus {
  background-color: #00a950;
  color: #000000;
}

只需在HTML导航栏中添加一个id，例如:

<nav id="navbar-yellow" class="navbar navbar-default navbar-fixed-top" role="navigation">

有了这个id，你可以设置导航栏的颜色，还可以设置链接和下拉菜单

应用于不同类型导航条的例子

黑色的

黄色的

Darkblue

红色(樱桃)

Darkgreen

这是CSS

例子

试着这样做:

<!-- A dark one -->
<nav class="navbar navbar-inverse" role="navigation"></nav>

默认的主要颜色使用如下:

导航栏背景:#F8F8F8 导航栏边框:#E7E7E7 默认颜色:#777 Nav-brand Hover颜色:#5E5E5E 悬停颜色:#333 活动背景:#D5D5D5 主动色:#555

你可以了解更多在Twitter引导3中改变导航栏颜色。

你需要直接更改CSS吗?是什么……

<nav class="navbar navbar-inverse" style="background-color: #333399;">
<div class="container-fluid">
<div class="navbar-header">
  <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar">

  </button>
  <a class="navbar-brand" href="#">Logo</a>
</div>
<div class="collapse navbar-collapse" id="myNavbar">

Available navbars

你有两个基本的导航条:

<!-- A light one -->
<nav class="navbar navbar-default" role="navigation"></nav>
<!-- A dark one -->
<nav class="navbar navbar-inverse" role="navigation"></nav>

默认颜色使用

以下是主要颜色及其用法:

#F8F8F8:导航栏背景 #E7E7E7:导航栏边框 #777:默认颜色 #333:悬停颜色(.nav-brand为#5E5E5E) #555:主动色 #D5D5D5:活动背景

默认样式

如果你想放一些自定义样式，这里是你需要改变的CSS:

/* navbar */
.navbar-default {
    background-color: #F8F8F8;
    border-color: #E7E7E7;
}
/* Title */
.navbar-default .navbar-brand {
    color: #777;
}
.navbar-default .navbar-brand:hover,
.navbar-default .navbar-brand:focus {
    color: #5E5E5E;
}
/* Link */
.navbar-default .navbar-nav > li > a {
    color: #777;
}
.navbar-default .navbar-nav > li > a:hover,
.navbar-default .navbar-nav > li > a:focus {
    color: #333;
}
.navbar-default .navbar-nav > .active > a,
.navbar-default .navbar-nav > .active > a:hover,
.navbar-default .navbar-nav > .active > a:focus {
    color: #555;
    background-color: #E7E7E7;

}
/* Caret */
.navbar-default .navbar-nav > .dropdown > a .caret {
    border-top-color: #777;
    border-bottom-color: #777;
}
.navbar-default .navbar-nav > .dropdown > a:hover .caret,
.navbar-default .navbar-nav > .dropdown > a:focus .caret {
    border-top-color: #333;
    border-bottom-color: #333;
}
.navbar-default .navbar-nav > .open > a .caret,
.navbar-default .navbar-nav > .open > a:hover .caret,
.navbar-default .navbar-nav > .open > a:focus .caret {
    border-top-color: #555;
    border-bottom-color: #555;
}
/* Mobile version */
.navbar-default .navbar-toggle {
    border-color: #DDD;
}
.navbar-default .navbar-toggle:hover,
.navbar-default .navbar-toggle:focus {
    background-color: #DDD;
}
.navbar-default .navbar-toggle .icon-bar {
    background-color: #CCC;
}
@media (max-width: 767px) {
    .navbar-default .navbar-nav .open .dropdown-menu > li > a {
        color: #777;
    }
    .navbar-default .navbar-nav .open .dropdown-menu > li > a:hover,
    .navbar-default .navbar-nav .open .dropdown-menu > li > a:focus {
          color: #333;
    }
}

自定义彩色导航条示例

下面是自定义彩色导航条的四个例子:

SCSS代码:

$bgDefault   : #e74c3c;
$bgHighlight : #c0392b;
$colDefault  : #ecf0f1;
$colHighlight: #ffbbbc;
.navbar-default {
  background-color: $bgDefault;
  border-color: $bgHighlight;
  .navbar-brand {
    color: $colDefault;
    &:hover, &:focus {
      color: $colHighlight; }}
  .navbar-text {
    color: $colDefault; }
  .navbar-nav {
    > li {
      > a {
        color: $colDefault;
        &:hover,  &:focus {
          color: $colHighlight; }}}
    > .active {
      > a, > a:hover, > a:focus {
        color: $colHighlight;
        background-color: $bgHighlight; }}
    > .open {
      > a, > a:hover, > a:focus {
        color: $colHighlight;
        background-color: $bgHighlight; }}}
  .navbar-toggle {
    border-color: $bgHighlight;
    &:hover, &:focus {
      background-color: $bgHighlight; }
    .icon-bar {
      background-color: $colDefault; }}
  .navbar-collapse,
  .navbar-form {
    border-color: $colDefault; }
  .navbar-link {
    color: $colDefault;
    &:hover {
      color: $colHighlight; }}}
@media (max-width: 767px) {
  .navbar-default .navbar-nav .open .dropdown-menu {
    > li > a {
      color: $colDefault;
      &:hover, &:focus {
        color: $colHighlight; }}
    > .active {
      > a, > a:hover, > a:focus, {
        color: $colHighlight;
        background-color: $bgHighlight; }}}
}

最后，一个小礼物

我刚刚做了一个脚本，它将允许你生成你的主题: TWBSColor -生成自己的引导导航栏

[更新]:TWBSColor现在生成SCSS/SASS/Less/CSS代码。 [更新]:从现在开始，您可以使用Less作为TWBSColor提供的默认语言 [更新]:TWBSColor现在支持下拉菜单着色 [更新]:TWBSColor现在允许选择你的版本(Bootstrap 4支持添加)

如果只是改变导航条的颜色，我的建议是使用:Bootstrap Magic。您可以更改导航栏的不同属性的值并查看预览。

以自定义CSS样式表或Less variables文件的形式下载结果。您可以通过输入字段和颜色选择器更改值。
