版本说明：    - 在线工具：Bootstrap 3.3.2+ / 4.0.0+    - 这个回答：Bootstrap 3.0.x

可用的导航栏

你有两个基本的导航栏：

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

默认颜色用法

以下是主要颜色及其用法：

  • #F8F8F8：navbar background
  • #E7E7E7：navbar border
  • #777：默认颜色
  • #333：悬停颜色（#5E5E5E）
    • 的.nav-brand
  • #555：活跃的颜色
  • #D5D5D5：有效背景

默认样式

如果你想要一些自定义样式，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;
}
.navbar-default .navbar-nav > .open > a,
.navbar-default .navbar-nav > .open > a:hover,
.navbar-default .navbar-nav > .open > a:focus {
    color: #555;
    background-color: #D5D5D5;
}
/* 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;
    }
}

自定义彩色导航栏示例

以下是自定义彩色导航栏的四个示例：

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

我刚刚制作了一个脚本，可以让你生成你的主题： 的 TWBSColor - Generate your own Bootstrap navbar

[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（添加了Bootstrap 4支持）

答案 1 :(得分：187)

针对Bootstrap 4更新了2018

在Bootstrap 4中更改导航栏颜色是不同的（并且更容易一些）。您可以创建自定义导航栏类​​，然后引用它来更改导航栏而不影响其他Bootstrap导航.. 

<nav class="navbar navbar-custom">...</nav>

Bootstrap 4.0

更改导航栏所需的CSS在Bootstrap 4 ...

中要少得多 
.navbar-custom {
    background-color: #ff5500;
}
/* change the brand and text color */
.navbar-custom .navbar-brand,
.navbar-custom .navbar-text {
    color: rgba(255,255,255,.8);
}
/* change the link color */
.navbar-custom .navbar-nav .nav-link {
    color: rgba(255,255,255,.5);
}
/* change the color of active or hovered links */
.navbar-custom .nav-item.active .nav-link,
.navbar-custom .nav-item:hover .nav-link {
    color: #ffffff;
}

Bootstrap 4 Custom Navbar Demo enter image description here

更改活动/悬停链接 背景颜色也适用于相同的CSS，但如果您希望bg颜色填充整个高度，则必须调整填充链接......

py-0从整个导航栏中删除垂直填充...

<nav class="navbar navbar-expand-sm navbar-custom py-0">..</nav> 

/* change the link color and padding  */
.navbar-custom .navbar-nav .nav-link {
    color: rgba(255,255,255,.5);
    padding: .75rem 1rem;
}

/* change the color and background color of active links */
.navbar-custom .nav-item.active .nav-link,
.navbar-custom .nav-item:hover .nav-link {
    color: #ffffff;
    background-color: #333;
}

如果Navbar有下拉列表，请添加以下内容以更改下拉颜色：

/* for dropdowns only */
.navbar-custom .navbar-nav .dropdown-menu  { 
  background-color: #33aa33;
}
.navbar-custom .navbar-nav .dropdown-menu>li>a  { 
  color: #fff;
}
.navbar-custom .navbar-nav .dropdown-menu>li>a:hover,.navbar-custom .navbar-nav .dropdown-menu>li>a:focus  { 
  color: #33aa33;
}

答案 2 :(得分：48)

使用Less

您还可以考虑编译自己的版本。尝试http://getbootstrap.com/customize/（其中包含Navbars设置的分隔部分（默认导航栏和反向导航栏））或从https://github.com/twbs/bootstrap下载您自己的副本。

您可以在variables.less中找到导航栏设置。 navbar.less用于编译导航栏（取决于variables.less和mixins.less）。

复制'navbar-default部分'并填写您自己的颜色设置。更改variables.less中的变量将是最简单的方法（更改默认或反向导航栏不会有问题，因为每页只有一个导航栏）。

在大多数情况下，您不会更改所有设置：

// Navbar
// -------------------------

// Basics of a navbar
@navbar-height:                    50px;
@navbar-margin-bottom:             @line-height-computed;
@navbar-default-color:             #777;
@navbar-default-bg:                #f8f8f8;
@navbar-default-border:            darken(@navbar-default-bg, 6.5%);
@navbar-border-radius:             @border-radius-base;
@navbar-padding-horizontal:        floor(@grid-gutter-width / 2);
@navbar-padding-vertical:          ((@navbar-height - @line-height-computed) / 2);

// Navbar links
@navbar-default-link-color:                #777;
@navbar-default-link-hover-color:          #333;
@navbar-default-link-hover-bg:             transparent;
@navbar-default-link-active-color:         #555;
@navbar-default-link-active-bg:            darken(@navbar-default-bg, 6.5%);
@navbar-default-link-disabled-color:       #ccc;
@navbar-default-link-disabled-bg:          transparent;

// Navbar brand label
@navbar-default-brand-color:               @navbar-default-link-color;
@navbar-default-brand-hover-color:         darken(@navbar-default-link-color, 10%);
@navbar-default-brand-hover-bg:            transparent;

// Navbar toggle
@navbar-default-toggle-hover-bg:           #ddd;
@navbar-default-toggle-icon-bar-bg:        #ccc;
@navbar-default-toggle-border-color:       #ddd;

您也可以尝试http://twitterbootstrap3navbars.w3masters.nl/。此工具为您的自定义导航栏生成CSS代码。或者，您也可以向导航栏添加渐变颜色和边框。

答案 3 :(得分：48)

我花了一段时间，但我发现包含以下内容的原因是可以更改导航栏颜色：

.navbar{ 
    background-image: none;
}

答案 4 :(得分：10)

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">

使用此ID，您可以设置导航栏颜色的样式，还可以设置链接和下拉列表的样式

应用于不同类型导航栏的示例

Black

Yellow

Darkblue

Red (Cherry)

Darkgreen

这是CSS

您是否必须直接更改CSS？怎么样...... 

<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">
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>                        
  </button>
  <a class="navbar-brand" href="#">Logo</a>
</div>
<div class="collapse navbar-collapse" id="myNavbar">
  <ul class="nav navbar-nav">
    <li class="active"><a href="#">Home</a></li>
    <li><a href="#">About</a></li>
    <li><a href="#">Projects</a></li>

如果只是改变导航栏的颜色，我建议使用：Bootstrap Magic。您可以更改导航栏的不同属性的值并查看预览。将结果下载为自定义CSS样式表或LESS变量文件。您可以使用输入字段和颜色选择器更改值。 ÿ

在此导航栏CSS中，设置为自己的颜色：

＆＃13;
＆＃13; 
/* 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;

在twittter bootstrap中提及反向和defult类名称会导致它们呈现黑白颜色。 更好的是你不应该覆盖它并在其附近添加一个类并为你写出特定的样式

my_style{
background-color:green;
}

像这样。谢谢。

.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;
    }
}

  • Navbar背景：＃F8F8F8
  • Navbar Border：＃E7E7E7
  • 默认颜色：＃777
  • 导航品牌悬停颜色：＃5E5E5E

从引导程序4开始，您应该使用'bg'元素轻松更改导航栏的颜色。 https://stackoverflow.com/a/55610596/11061852

答案 13 :(得分：-1)

可以直接使用 style =“”属性来覆盖您想要覆盖它的任何html标记。

<nav class="navbar navbar-default" style="font-weight: bold; background-color: #569AAB;">

这会覆盖bootstrap的默认CSS。

无需单独定义完整的样式集或CSS。
