要设置3D元素的底部位置，请使用JavaScript PerspectiveOrigin属性。
您可以尝试运行以下代码来使用JavaScript设置3D元素的底部位置。我们的代码中有三个div-
<!DOCTYPE html>
<html>
<head>
<style>
#div1 {
position: relative;
margin: auto;
height: 200px;
width: 200px;
padding: 20px;
border: 2px solid blue;
perspective: 100px;
}
#div2 {
padding: 80px;
position: absolute;
border: 2px solid BLUE;
background-color: yellow;
transform: rotateX(45deg);
}
#div3 {
padding: 50px;
position: absolute;
border: 2px solid BLUE;
background-color: green;
transform: rotateX(30deg);
}
</style>
</head>
<body>
<p>Change the property of div</p>
<button onclick = " display ()">Set Perspective Origin Position</button>
<div id = "div1">DIV1
<div id = "div2">DIV2</div>
<div id = "div3">DIV3</div>
</div>
<script>
function display() {
document.getElementById("div1").style.perspectiveOrigin = "20px 10%";
}
</script>
</body>
</html>
