直接上代码，只需切换class就可看效果
<!DOCTYPE html>
<html>
<head>
<title>水平垂直居中</title>
<style type="text/css">
*{
margin: 0;
padding: 0;
}
.myDiv{
width:200px;
height: 200px;
background: lightblue;
}
/*方法一*/
.divToCenter1{
position: absolute;
top:0;
left: 0;
bottom: 0;
right: 0;
margin: auto;
}
/*方法二*/
.divToCenter2{
position:absolute;
top:50%;
left:50%;
margin:-100px;
}
/*方法三*/
.divToCenter3{
position: absolute;
top: 50%;
left:50%;
transform: translate(-50%,-50%);
}
</style>
</head>
<body>
<div class="myDiv divToCenter3">
