看看这个CodePen看看我的意思：

.perspective-container {
  margin: 50px 0;
  perspective: 1000px;
  perspective-origin: 0 50%;
}
.card {
  border: 10px solid blue;
  width: 300px;
  height: 300px;
  overflow: hidden;
  transform: rotateY(-45deg);
}
.card-inner {
  width: 300px;
  height: 300px;
  overflow: hidden;
}
.scroller {
  transform: translate(0, -100px);
}
.scroller-3d {
  transform: translate3d(0, -100px, 0);
}
.will-change {
  will-change: transform;
}

我有一个应用了透视的旋转元素，在其中我有一个垂直转换的“滚动”div（想象一下杂志翻页体验，每个页面内都有滚动 div）。我添加will-change: transform到内部 div 并破坏了外部容器overflow: hidden。这似乎是 Chrome 合成器的一个错误。

有谁知道任何解决方法？我想保留该will-change属性，因为它显着加快了移动 Chrome 上的动画速度。

编辑：看起来这不是特定于 will-change 属性，而是任何使内部 div 成为自己的合成层的属性。当我删除该will-change属性但将转换更改为translate3d类似提高性能并显示错误的 a 时。内部 div 上唯一允许旋转的父对象正确渲染overflow: hidden的类是添加 2D 变换的类。

试试这样的CodePen：

.container {
  margin: 75px 0;
}

.card {
  border: 10px solid blue;
  width: 300px;
  height: 300px;
  overflow: hidden;
  -webkit-transform: perspective(1000px) rotateY(-45deg);
  transform: perspective(1000px) rotateY(-45deg);
  -webkit-transform-origin: 0 50%;
  transform-origin: 0 50%;
}

.scroller {
  -webkit-transform: translate(0, -100px);
  transform: translate(0, -100px);
}

.scroller-3d {
  -webkit-transform: translate3d(0, -100px, 0);
  transform: translate3d(0, -100px, 0);
}

.will-change {
  will-change: transform;
}

你可以玩perspective()和transform-origin价值观。
