<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Document</title>
  <style>
    div{
      position: absolute;
      top: 50%;
      left: 50%;
      width: 200px;
      height: 200px;
      /* line-height: 200px; */
      text-align: center;
      background-color: pink;
      /* 变换平移 */
      transform: translate(-50%,-50%);
    }
    p{
      position: absolute;
      top: 50%;
      left: 50%;
      /* 变化平移 */
      transform: translate(-50%,-50%);
    }
  </style>
</head>
<body>
  <div>    
    <p>transform: translate(50%,50%); 水平垂直居中对齐</p>
  </div>
</body>
</html>

 

结果

 transition    翻译为过度  scale   翻译为大小
