bootstrap导航栏颜色设置
给nav设置hover、focus、active时要注意顺序，防止颜色覆盖。
该例中添加了二级菜单
实现效果如下：
<!DOCTYPE html>
<html><head>
<meta charset="utf-8">
<title> 首页</title>
<meta name="viewport" content="width=device-width,maximum-scale=1.0,initial-scale=1.0,user-scalable=no">
<link rel="stylesheet" href="css/bootstrap.css">
<link rel="stylesheet" href="css/bootindex.css">
<script src="http://libs.baidu.com/jquery/2.0.0/jquery.min.js"></script>
<script src="js/bootstrap.js"></script>
</head>
<body>
<nav class="navbar navbar-default navbar-fixed-top" role="navigation"> <div class="navbar-header"> <a class="navbar-brand" href="#">Penguins blog</a> </div> <div"> <ul class="nav navbar-nav navbar-center"> <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown">下拉菜单<b class="caret"></b></a> <ul class="dropdown-menu"> <li><a href="#">菜单一</a></li> <li><a href="#">菜单二</a></li> <li><a href="#">菜单三</a></li> <li class="divider"></li> <li><a href="#">分离</a></li> </ul> </li> <li><a href="#">个人博客</a> </li> </ul> </div> </nav> </body> </html>
css代码：
.navbar{ margin-bottom: 0px; border-radius: 5px; background: #ff0000; } .navbar .nav > li > a{ color: #000000; } .navbar .nav >li >a:visited{ color: aqua; background-color: #0000ff; } .navbar .nav > li > a:hover { color: aqua; background-color: #000000; } .navbar .nav >li >a:active{ color: aqua; background-color: #00ff00; }
