使用CSS指定动画的速度曲线

使用 动画定时功能设置动画的速度曲线。您可以尝试运行以下代码来实现此目的

例

<!DOCTYPE html>
<html>
   <head>
      <style>
         div {
            width: 150px;
            height: 200px;
            position: relative;
            background-color: yellow;
            animation-name: myanim;
            animation-duration: 2s;
            animation-direction: alternate-reverse;
            animation-iteration-count: 3;
         }
         @keyframes myanim {
            from {left: 100px;}
            to {left: 200px;}
         }
         #demo1 {animation-timing-function: ease;}
         #demo2 {animation-timing-function: ease-in;}
      </style>
   </head>
   <body>
      <div id = "demo1">ease effect</div>
      <div id = "demo2">ease-in effect</div>
   </body>
</html>
