我将如何修改 CSS 以更改 Twitter Bootstrap 中导航栏的颜色?
12 回答
tl;dr - TWBSColor - 生成你自己的引导导航栏
版本说明: - 在线工具:Bootstrap 3.3.2+ / 4.0.0+ - 这个答案: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 (#5E5E5E
for.nav-brand
)#555
: 活跃的颜色#D5D5D5
: 活动背景
默认样式
如果您想添加一些自定义样式,这里是您需要更改的 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:
和 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: TWBSColor - 生成你自己的引导导航栏
[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 现在允许选择您的版本(添加了 Bootstrap 4 支持)
引导程序 5(2021 年更新)
默认情况下,导航栏在 Bootstrap 5 中是透明的。自 Bootstrap 4 以来,在更改导航栏背景颜色、文本颜色、链接、下拉和悬停样式方面没有太大变化。
/* change the background color */
.navbar-custom {
background-color: #4433cc;
}
/* change the brand and text color */
.navbar-custom .navbar-brand,
.navbar-custom .navbar-text {
color: #ffcc00;
}
/* change the link color */
.navbar-custom .navbar-nav .nav-link {
color: #ffbb00;
}
/* change the color of active or hovered links */
.navbar-custom .nav-item.active .nav-link,
.navbar-custom .nav-item:focus .nav-link,
.navbar-custom .nav-item:hover .nav-link {
color: pink;
}
/* for dropdowns only */
.navbar-custom .navbar-nav .dropdown-menu {
background-color: #ddaa11;
}
/* dropdown item text color */
.navbar-custom .navbar-nav .dropdown-item {
color: #000000;
}
/* dropdown item hover or focus */
.navbar-custom .navbar-nav .dropdown-item:hover,
.navbar-custom .navbar-nav .dropdown-item:focus {
color: #eeeeee;
background-color: red;
}
引导程序 4.3(2020 年更新)
在Bootstrap 4中更改导航栏颜色是不同的(而且更容易一些)。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>
引导 4.3+
在 Bootstrap 4 中更改导航栏所需的 CSS 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;
}
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 颜色填充链接的整个高度,则必须调整填充...
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;
}

**引导程序 3**
<nav class="navbar navbar-custom">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">...
</button>
<a class="navbar-brand" href="#">Title</a>
</div>
...
</nav>
.navbar-custom {
background-color:#229922;
color:#ffffff;
border-radius:0;
}
.navbar-custom .navbar-nav > li > a {
color:#fff;
}
.navbar-custom .navbar-nav > .active > a {
color: #ffffff;
background-color:transparent;
}
.navbar-custom .navbar-nav > li > a:hover,
.navbar-custom .navbar-nav > li > a:focus,
.navbar-custom .navbar-nav > .active > a:hover,
.navbar-custom .navbar-nav > .active > a:focus,
.navbar-custom .navbar-nav > .open >a {
text-decoration: none;
background-color: #33aa33;
}
.navbar-custom .navbar-brand {
color:#eeeeee;
}
.navbar-custom .navbar-toggle {
background-color:#eeeeee;
}
.navbar-custom .icon-bar {
background-color:#33aa33;
}
如果导航栏有下拉菜单,请添加以下内容以更改下拉菜单颜色:
/* 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;
}
如果您想一起更改主题颜色(导航栏之外),请参阅此答案
我花了一段时间,但我发现包括以下内容可以更改导航栏颜色:
.navbar{
background-image: none;
}
少用
你也可以考虑编译你自己的版本。尝试http://getbootstrap.com/customize/(其中有一个单独的导航栏设置部分(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。
您将在 中找到导航栏设置variables.less
。navbar.less
用于编译导航栏(取决于variables.less
和mixins.less
)。
复制“导航栏默认部分”并填写您自己的颜色设置。更改变量variables.less
将是最简单的方法(更改默认或反向导航栏不会成为问题,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;
你也可以试试http://twitterbootstrap3navbars.w3masters.nl/。此工具为您的自定义导航栏生成 CSS 代码。或者,您还可以向导航栏添加渐变颜色和边框。
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菜单的样式
应用于不同类型导航栏的示例

您必须直接更改CSS吗?关于什么...
<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">
<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>
<li><a href="#">Contact</a></li>
</ul>
<ul class="nav navbar-nav navbar-right">
<li><a href="#"><span class="glyphicon glyphicon-log-in"></span> Login</a></li>
</ul>
</div>
也试试这个。这对我有用。
.navbar-default .navbar-nav > li > a:hover,
.navbar-default .navbar-nav > li > a:focus {
background-color: #00a950;
color: #000000;
}
如果只是改变导航栏的颜色,我的建议是使用:Bootstrap Magic。您可以更改导航栏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。
在这个导航栏 CSS 中,设置为自己的颜色:
/* 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;
}
