要使用CSS在Perspective属性上实现动画，您可以尝试运行以下代码
<!DOCTYPE html>
<html>
<head>
<style>
#demo1 {
position: relative;
margin-left: 120px;
height: 250px;
width: 350px;
padding: 10px;
border: 1px solid orange;
animation: myanim 3s infinite;
perspective: 200px;
}
@keyframes myanim {
50% {
perspective: 100px;
}
}
#demo2 {
padding: 90px;
position: absolute;
border: 1px solid black;
background-color: orange;
transform: rotateX(60deg);
}
</style>
</head>
<body>
<div id = "demo1">This is demo text in div1.
<div id = "demo2">This is demo text in div2.</div>
</div>
</body>
</html>
