使用transform创建外观整洁的立方体

<div class="cube">
  <div class="face front">Front</div>
  <div class="face back">Back</div>
  <div class="face top">Top</div>
  <div class="face bottom">Bottom</div>
  <div class="face left">Left</div>
  <div class="face right">Right</div>
</div>

.cube {
  width: 200px;
  height: 200px;
  position: relative;
  transform-style: preserve-3d;
  transform: rotateX(0deg) rotateY(0deg);
  animation: rotate 10s infinite linear;
}

.face {
  position: absolute;
  width: 200px;
  height: 200px;
  background-color: #ccc;
  border: 1px solid #999;
}

.front {
  transform: translateZ(100px);
}

.back {
  transform: translateZ(-100px) rotateY(180deg);
}

.top {
  transform: rotateX(90deg) translateZ(100px);
}

.bottom {
  transform: rotateX(-90deg) translateZ(100px);
}

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

.right {
  transform: rotateY(90deg) translateZ(100px);
}

@keyframes rotate {
  0% {
    transform: rotateX(0deg) rotateY(0deg);
  }
  100% {
    transform: rotateX(360deg) rotateY(360deg);
  }
}
