盒子垂直居中，水平居中实现例子

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
</head>

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

</html>

<style>
    body {
        margin: 0;
    }

    div {
        position: absolute;
        width: 200px;
        height: 200px;
        left: 50%;
        top: 50%;
        margin-left: -100px;
        margin-top: -100px;
        background-color: red;

    }
</style>

 可以使用更简单的方式

 div {
        position: absolute;
        width: 200px;
        height: 200px;
        left: 50%;
        top: 50%;
        transform: translate(-50%, -50%);
        background-color: red;
    }
