这是html部分

<!DOCTYPE html> <html lang="en"> <head>     <meta charset="UTF-8">     <title>myblog</title>     <link href="http://cdn.bootcss.com/bootstrap/3.3.1/css/bootstrap.min.css" rel="stylesheet">     <script src="http://cdn.bootcss.com/jquery/3.0.0/jquery.min.js"></script>     <script src="http://cdn.bootcss.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>     <link rel="stylesheet" href="css/style.css"> </head> <body> <!--navigation-->         <nav class="navbar-inverse navbar-fixed-top" role="navigation">     <div class="container">     <div class="navbar-header">       <button class="navbar-toggle" type="botton" data-toggle="collapse" data-target=".navbar-collapse">           <span class="icon-bar"></span>           <span class="icon-bar"></span>           <span class="icon-bar"></span>       </button>       <a href="#" class="navbar-brand">Blog</a>     </div>     <div class="navbar-collapse collapse">         <ul class="nav navbar-nav">             <li class="active"><a href="#">主页</a></li>             <li><a href="#">关于本站</a></li>             <li><a href="#">留言墙</a></li>               <form class="navbar-form navbar-right" rloe="form">                 <div class="form-group">                 <input type="text" class="form-control" placeholder="输入搜索内容">                 </div>                 <button type="submit" class="btn btn-default navbar-btn">search</button>               </form>         </ul>     </div>     </nav>   </div> </body> </html>

这是css部分

.navbar-brand{     padding-top: 25px;     padding-bottom: 20px; } .navbar-inverse{     background-color: #303542 !important;     height: 65px; } .navbar-toggle{     padding-top: 15px; } .nav li a{     color: blue !important;     font: "微软雅黑";     font-weight: 500;     padding-top: 25px;     padding-bottom: 20px; } .nav li a:hover, .nav li a:active{     background-color: #1abc9c !important;     transition: all .3s ease-in-out; } .nav li.active a, .nav li.active a:hover, .nav li.active a:focus{     background-color: #1abc9c !important; } .navbar-form{     position: absolute;     right: 25%; } @media (max-width:767px){     .navbar-form{         visibility: hidden;     } }

这样的话对class为container的外层div设置背景颜色就行
