Question

我正在尝试构建一个金字塔并为其设置动画。问题是在围绕X轴旋转之后，我尝试围绕金字塔的高度（Y轴）旋转它，但我每次都移动它。我基本上尝试了每个transform-origin选项，但它不起作用。我的代码如下：

感谢您的帮助

.cube{
  margin: 100px 200px;
}

.pyramid{
  width: 0; 
  position: relative;
  transform-style: preserve-3d;
  animation: spin-pyramid 20s ease infinite alternate;
}

.base{
  width: 200px;
  height: 200px;
  background: rgba(255,0,0,.5);
  position: absolute;
}

.side{
  width: 0;
  height: 0;
  border-bottom: 141.421px solid rgba(255, 255, 0, 0.5);
  border-left: 100px solid transparent;
  border-right: 100px solid transparent;
  position: absolute;
  top: 100px; 
  left: 0;
  transform-origin: 50% 0; 
  }

.side-1{
  transform: translateZ(100px) rotateX(-45deg);
}

.side-2{
  border-bottom-color: rgba(0, 255, 255, 0.5);
  transform: rotateZ(90deg) translateZ(100px) rotateX(-45deg);
}

.side-3{
  border-bottom-color: rgba(255, 0, 255, 0.5);
  transform: rotateZ(180deg) translateZ(100px) rotateX(-45deg);
}

.side-4{
  border-bottom-color: rgba(0, 255, 0, 0.5);
  transform: rotateZ(270deg) translateZ(100px) rotateX(-45deg);
}

@keyframes spin-pyramid {
  10%{transform: rotateX(90deg);}
  25%{transform: rotateY(90deg) rotateX(90deg);}
  50%{transform: rotateY(180deg) rotateX(90deg);}
  75%{transform: rotateY(270deg) rotateX(90deg);}
  100%{transform: rotateY(360deg) rotateX(90deg);}
}

只需从 .base 中删除position:absolute，然后从 .pyramid 删除width:0，然后添加display:inline-block。

这将为金字塔元素（您想要旋转）提供基座的高度和宽度，因此旋转将相对于基座执行。

.cube {
  margin: 100px 200px;
}

.pyramid {
  position: relative;
  display:inline-block;
  transform-style: preserve-3d;
  animation: spin-pyramid 20s ease infinite alternate;
}

.base {
  width: 200px;
  height: 200px;
  background: rgba(255, 0, 0, .5);
}

.side {
  height:0;
  width:0;
  border-bottom: 141.421px solid rgba(255, 255, 0, 0.5);
  border-left: 100px solid transparent;
  border-right: 100px solid transparent;
  position: absolute;
  top: 100px;
  left: 0;
  transform-origin: 50% 0;
}

.side-1 {
  transform: translateZ(100px) rotateX(-45deg);
}

.side-2 {
  border-bottom-color: rgba(0, 255, 255, 0.5);
  transform: rotateZ(90deg) translateZ(100px) rotateX(-45deg);
}

.side-3 {
  border-bottom-color: rgba(255, 0, 255, 0.5);
  transform: rotateZ(180deg) translateZ(100px) rotateX(-45deg);
}

.side-4 {
  border-bottom-color: rgba(0, 255, 0, 0.5);
  transform: rotateZ(270deg) translateZ(100px) rotateX(-45deg);
}

@keyframes spin-pyramid {
  10% {
    transform: rotateX(90deg);
  }
  25% {
    transform: rotateY(90deg) rotateX(90deg);
  }
  50% {
    transform: rotateY(180deg) rotateX(90deg);
  }
  75% {
    transform: rotateY(270deg) rotateX(90deg);
  }
  100% {
    transform: rotateY(360deg) rotateX(90deg);
  }
}
