采用原生JS及CSS 3.0实现一个金字塔的效果，这个特效在实际工作中用处不大，纯属娱乐。
实现代码如下：
代码语言：javascript复制<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>原生JS实现立体金字塔</title>
<style type="text/css">
* {
margin: 0;
padding: 0;
list-style: none;
}
#div1 {
width: 200px;
height: 200px;
position: absolute;
left: 50%;
top: 50%;
margin: -100px 0 0 -100px;
background: black;
transform-style: preserve-3d;
}
</style>
</head>
<body>
<div id='div1'></div>
<script type="text/javascript">
for (var i = 0; i < 100; i ) {
var oDiv = document.createElement('div');
oDiv.style.width = (200 - i * 2) 'px';
oDiv.style.height = (200 - i * 2) 'px';
oDiv.style.position = 'absolute';
oDiv.style.transition = Math.random() * 1 's';
oDiv.style.left = '0';
oDiv.style.top = '0';
oDiv.style.right = '0';
oDiv.style.bottom = '0';
oDiv.style.margin = 'auto';
oDiv.style.transform = 'translateZ(' i 'px)';
oDiv.style.background = 'rgb(' parseInt(Math.random() * 256) ',' parseInt(Math.random() * 256) ',' parseInt(Math.random() * 256) ')';
div1.appendChild(oDiv);
}
var reg = 0;
setInterval(function () {
reg = 0.4;
div1.style.transform = 'perspective(800px) rotateX(' reg 'deg)';
}, 6);
</script>
</body>
</html>
