我怎么去修改CSS来改变Twitter引导导航栏的颜色?
当前回答
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。

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;
}

用更少的
您还可以考虑编译自己的版本。尝试http://getbootstrap.com/customize/(其中有一个单独的部分导航栏设置(默认导航栏和反向导航栏))或从https://github.com/twbs/bootstrap下载自己的拷贝。
你可以在variables.less中找到导航栏设置。导航条。Less用于编译导航栏(取决于变量)。Less and mixins.less)。
复制“navbar-default section”并填充你自己的颜色设置。在变量中改变变量。减少导航条是最简单的方法(更改默认或反向导航条不会有问题，因为每个页面只有一个导航条)。
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/。这个工具为你的自定义导航栏生成CSS代码。你还可以在导航栏上添加渐变颜色和边框。
在Twitter Bootstrap中提到的逆类和默认类名导致它们是黑色和白色的。
更好的是，你不应该重写它，并在它附近添加一个类，并为它编写特定的样式:
my_style { 背景颜色:绿色; ｝
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
