我怎么去修改CSS来改变Twitter引导导航栏的颜色?
当前回答
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

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。
引导5(更新2021年)
默认情况下，引导5中的导航栏是透明的。自Bootstrap 4以来，导航栏背景颜色、文本颜色、链接、下拉菜单和悬停样式的变化不大。
/* 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 {

/* dropdown item hover or focus */
.navbar-custom .navbar-nav .dropdown-item:hover,
.navbar-custom .navbar-nav .dropdown-item:focus {

background-color: red;
}

Bootstrap 4.3(2020年更新)
在Bootstrap 4中改变导航条的颜色是不同的(而且更容易一点)。你可以创建一个自定义导航栏类，然后引用它来改变导航栏，而不影响其他引导导航。
<nav class="navbar navbar-custom">...</nav>
引导 4.3+
在Bootstrap 4中，需要更改导航栏的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;
}
引导4自定义导航条演示
改变活动/悬停链接的背景色也适用于相同的CSS，但如果你想让bg颜色填充整个链接的高度，你必须调整填充…
Py-0删除垂直填充从整个导航栏…
<nav class="navbar - navbar-expand-sm navbar-custom py-0">.
/* 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;
}

自定义导航条演示Bootply
如果导航栏有下拉菜单，添加以下内容来改变下拉菜单的颜色:
/* for dropdowns only */
.navbar-custom .navbar-nav .dropdown-menu {
background-color: #33aa33;
}
.navbar-custom .navbar-nav .dropdown-menu>li>a {
color: #fff;

如果你想一起改变主题颜色(在导航栏之外)，请看这个答案
这花了我一段时间，但我发现包括以下内容可以改变导航栏的颜色:
.navbar{
background-image: none;
}
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; } /* 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; }
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; ｝
