有没有办法在我的浏览器只与CSS的使用中心垂直对齐一个div？
下面是做这件事：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<style>
html {
display: table;
width: 100%;
height: 100%
}
body {
display: table-row;
margin: 0;
height: 100%
}
#foo {
display: table-cell;
height: 100%;
vertical-align: middle
}
#test {
margin: auto;
background-color: #ccc
}
</style>
</head>
<body>
<div id="foo">
<div id="test">Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur.

</div>
</body>
</html>
