Question

我有一个：before和a：after元素（用于阴影），带有一个变换：旋转应用于它。：在调整视口大小之前保持原位，然而：在稍微上下移动之后。如果旋转被移除，它将在调整大小时保持原位。如何通过漫游来调整大小？

我在：之前和之后放置了一个z-index：1，以便查看问题

它是影子＃3

我不认为使用翻译是这里的方式，我将容器设置为位置：相对;然后使用绝对定位来定位阴影事物：http://jsfiddle.net/bpma9ko4/

这里有相关部分：

.shadow-box {
  width: 45%;
  margin: 0 1% 0 0;
  height: 100%;
  transition: all 0.2s ease-in-out;
  cursor: pointer;
  display: inline-block;
  position: relative;
}

.shadow-box:before, .shadow-box:after {
  content: '';
  z-index: 1;
  position: absolute;
  width: 40%;
  height: 110px;
  background: red;
  transform: skew(-10deg) rotate(-6deg);
  transition: all 0.2s ease-in-out;
  top: 20px;
  left: 20px;
}

.shadow-box:after {
  transform: skew(10deg) rotate(6deg);
  right: 20px;
  left: auto;
}

在您的示例中，当我删除翻译时，右侧的红色框位于图像下方（在新行上），然后您尝试使用翻译将其拖动，但对我来说，这是一种更直接的方式，如果您只需使用顶部/左/右属性将其放在图像上即可。

注意：我的示例已经过简化，没有阴影和其他内容，它会缩减到与问题相关的部分。
