纯css实现正多面体

正多面体css实现

这个正多面体是由很多个正方形div叠成的，虽然有很多窟窿，但是不影响整体效果。

代码

一个是html代码，一个是css代码

<!DOCTYPE html>

<script>
    let polyhedron = document.querySelector(".polyhedron");
    let rotateBase = polyhedron.querySelector(".rotateContainer");
    window.addEventListener("mousemove", (e) => {
        console.log(e.pageX);
        console.log(e.pageY);
        let k = 300;
        rotateBase.style.transform = `rotateX(${k * e.pageY / 1080}deg) rotateZ(${-k * e.pageX / 1920}deg)`;
    });
</script>
</html>

其实上面的css代码是less编译生成的，我写的是less代码

less代码如下：

* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}

.polyhedron {
  @iconBoxL: 100px;
  width: @iconBoxL;
  height: @iconBoxL;

  position: relative;
  margin: 600px auto;
  perspective: 800px;
  outline: solid 1px red;

  .rotateContainer {
    @cubeL: 100px; // 正方体的边长
    @containerL: @cubeL * 2;
    width: @containerL;
    height: @containerL;
    // 与旋转中心同心对齐
    position: absolute;
    left: 50%;
    top: 50%;
    margin-left: -(@containerL / 2);
    margin-top: -(@containerL / 2);

    transform-style: preserve-3d;
    transform-origin: 50% 50% (@cubeL/2)+(1.414/2*@cubeL);

    //transform: rotateX(60deg) rotateZ(30deg);
    outline: solid 1px green;

    .slide {
      outline: solid 1px;
