问题

我将如何修改CSS来改变Twitter Bootstrap 3中导航栏的颜色?



解决方法

tl;dr - TWBSColor - Generate your own Bootstrap navbar

Version notes:
- Online tool: Bootstrap 3.3.6 (maintained)
- This answer: Bootstrap 3.0.x

Available navbars

您有两个基本导航栏:

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

Default color usage

以下是主要颜色及其用途:

  • #F8F8F8 : navbar background
  • #E7E7E7 : navbar border
  • #777 : default color
  • #333 : hover color (#5E5E5E for .nav-brand)
  • #555 : active color
  • #D5D5D5 : active background

Default style

如果您想要放置一些自定义样式,那么您需要更改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;
    }
}

Custom colored navbar examples

以下是自订颜色导览列的4个范例:

在这里输入图片说明

以及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; }}}
}

And finally, a little gift

我刚刚制作了一个脚本,可以生成您的主题:
TWBSColor - 生成您自己的Bootstrap导航栏

[更新]:TWBSColor现在产生SCSS / SASS / LESS / CSS代码. [更新]:从现在起,您可以使用LESS作为TWBSColor提供的默认语言. [更新]:TWBSColor现在支持下拉菜单的着色

欢迎提出意见和通知.
