<head>
	<meta charset="UTF-8">
	<title>Document</title>
	<style type="text/css">
		*{
			margin:0;padding:0;list-style: none;text-decoration: none;
		}
		body{
			background: #ccc;
		}
		#container{
			background-image: url(backgroundImage.jpg);width: 1613px;height: 700px;margin:0 auto;
		}
		#logo{
			float: left;margin:-5px 5px 0 0;
		}
		form{
			background: white;float: left;
		}
		#search-input{
			outline:none;width:500px;height: 50px;line-height: 50px;float: left;border:0;

		}
		#wrapper{

		}
	</style>
</head>
<body>
	<div id="container">
		<div id="wrapper">
			<div id="logo">  <img src="http://www.mamicode.com/必应.png" alt="tupian" id="logo"> </div>
