CSS动画keyframes简单样例
一、代码部分
1.html
<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><meta name="viewport" content="width=device-width, initial-scale=1.0"><link rel="stylesheet" href="style.css"><title>Document</title>
</head>
<body><div class="circle1"></div><div class="circle2"></div>
</body>
</html>
2.css
.circle1{width: 180px;margin-top: 20px;background-color: green;height: 180px;border-radius: 50%;animation: test 4.0s ease-in-out infinite alternate;text-align: center;
}@keyframes test {0%{transform: translate(100px,100px);}20%{transform: translate(200px,200px);}50%{transform: translate(300px,300px);}80%{transform: translate(400px,200px);}100%{transform: translate(500px,100px);}

三、说明
以上代码实现了一个简单的移动的圆形，一个旋转变色的矩形。
后续可以用录屏软件，录屏后转为gif动图。
