动画animate 之动画序列

实现如上功能，需要分为五个状态，状态如下：

　　代码如下；

<!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 {
            width: 100px;
            height: 100px;
            background-color: pink;
            animation-name: move;
            animation-duration: 5s;
        }
        /* 
            1、可以做多个状态的变化 keyframe关键词
            2、里面的百分比要是整数
            3、里面的百分比就是总的时间（5s）的划分
         */
        @keyframes move {
            0% {
                transform: translate(0, 0);
            }
 
            25% {
                transform : translate(1000px, 0);
            }
 
            50% {
                transform : translate(1000px, 600px);
            }
 
            75% {
                transform: translate(0px, 600px);
            }
 
            100% {
                transform: translate(0, 0);
            }
        }
    </style>
</head>
<body>
    <div>
 
    </div>
</body>
</html>
