代码一样为什么不显示图片呢
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<style type="text/css ">
*{margin: 0;
padding: 0;}
.page{width: 100%;
height: 578px;
background: url("imooc.jpg") center top no-repeat;}
</style>
</head>
<body>
<div class="page"></div>
</body>
</html>
