html3d旋转魔方正方体代码

以下是一个简单的HTML和CSS 3D变换代码来实现3x3x3魔方正方体的旋转：

<div class="cube">
  <div class="side front">
    <div class="face"></div>
    <div class="face"></div>
    <div class="face"></div>
  </div>
  <div class="side back">
    <div class="face"></div>
    <div class="face"></div>
    <div class="face"></div>
  </div>
  <div class="side left">
    <div class="face"></div>
    <div class="face"></div>
    <div class="face"></div>
  </div>
  <div class="side right">
    <div class="face"></div>
    <div class="face"></div>
    <div class="face"></div>
  </div>
  <div class="side top">
    <div class="face"></div>
    <div class="face"></div>
    <div class="face"></div>
  </div>
  <div class="side bottom">
    <div class="face"></div>
    <div class="face"></div>
    <div class="face"></div>
  </div>
</div>

.cube {
  width: 300px;

  transform: rotateX(45deg) rotateY(45deg);
}

.side {
  position: absolute;
  width: 100px;
  height: 100px;
  background-color: transparent;
  border: 1px solid #000;
}

.front {
  transform: translateZ(150px);

  transform: rotateY(180deg) translateZ(150px);
}

  transform: rotateY(-90deg) translateZ(150px);

  transform: rotateY(90deg) translateZ(150px);
}

.top {
  transform: rotateX(90deg) translateZ(150px);
}

.bottom {
  transform: rotateX(-90deg) translateZ(150px);
}

.face {
  width: 100%;
  height: 100%;

.front .face:nth-child(1) {

  transform: rotateY(-90deg) translateZ(100px);
}

.back .face:nth-child(1) {
  background-color: #ff6600;
  transform: rotateY(180deg);
}

.back .face:nth-child(2) {
  background-color: #fff;
  transform: rotateY(-90deg) translateZ(100px);
}

.back .face:nth-child(3) {
  background-color: #00ff00;
  transform: rotateY(90deg) translateZ(100px);
}

.left .face:nth-child(1) {
  background-color: #ffff00;
  transform: rotateY(-90deg);
}

.left .face:nth-child(2) {
  background-color: #fff;
  transform: rotateX(-90deg) translateZ(100px);
}

.left .face:nth-child(3) {
  background-color: #ff00ff;
  transform: rotateX(90deg) translateZ(100px);
}

.right .face:nth-child(1) {
  background-color: #00ffff;
  transform: rotateY(90deg);
}

.right .face:nth-child(2) {
  background-color: #fff;
  transform: rotateX(90deg) translateZ(100px);
}

.right .face:nth-child(3) {
  background-color: #9900ff;
  transform: rotateX(-90deg) translateZ(100px);
}

.top .face:nth-child(1) {
  background-color: #cccccc;
  transform: rotateX(-90deg);
}

.top .face:nth-child(2) {
  background-color: #fff;
  transform: rotateY(180deg) translateZ(100px);
}

.top .face:nth-child(3) {
  background-color: #333;
  transform: rotateY(-90deg) translateZ(100px);
}

.bottom .face:nth-child(1) {
  background-color: #999;
  transform: rotateX(90deg);
}

.bottom .face:nth-child(2) {
  background-color: #fff;
  transform: translateZ(100px);
}

.bottom .face:nth-child(3) {
  background-color: #666;
  transform: rotateY(90deg) translateZ(100px);
}

在上面的代码中，我们使用了 `transform-style: preserve-3d` 属性来启用3D变换，使用 `transform: rotateX(45deg) rotateY(45deg)` 属性来旋转正方体。每个面使用 `transform: translateZ(150px)` 属性来放置到正方体的表面，并使用 `rotateX/Y/Z` 来确定它们的位置。每个面上还包含三个小面，使用不同的背景色来模拟魔方的颜色。通过旋转正方体来实现3x3x3魔方的旋转。
