怎样让内容居中在浏览器屏幕中间？使用定位后这个内容就不见了
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>全屏居中</title>
<style>
/*重置*/
body,ul,li,dl,dt,dd,h1,h2,h3,h4,h5,h6,p,input,b{ margin:0; padding:0; font-family:"微软雅黑"; font-size:12px;}
body,html{ overflow:hidden; background:#E0E0E0;}
body{ position:relative;}
li{ list-style:none;}
a{ text-decoration:none;}
.clearfix:after{ content:"."; height:0; visibility:hidden; display:block; clear:both;}
/*主要内容*/
.contbox{ width:600px; height:500px; background:#fff; position:absolute; top:50%; left:50%; margin-top:-250px; margin-left:-300px;}
</style>
</head>
<body>
<div class="contbox">
<h1>该语种网站正在建设中</h1>
<h5>敬请期待...</h5>
</div>

</html>
