由于溢出，bow-shadow被截断（已经说过），您还可以使用变换轻松地将阴影保持在可见区域内。

首先增加隐藏的溢出区域，然后减少里面的内容。更小它不会再被剪裁了。

这个想法的例子有一个简短的固定涉及：transform:scale(1.1)VStransform:scale(0.9)保持初始布局大小的接近比例。

.curtain {
  width: 550px;
  height: 250px;
  border-radius: 20px;
  position: relative;
  overflow: hidden;
  background: #000000;
  box-sizing: border-box;
}
.split-wrap{
transform:scale(1.1);
}
.jacketa {
  position: absolute;
  width: 180px;
  height: 180px;
  cursor: pointer;
  border-radius: 50%;
  background: #130e85;
  border: 3px solid #f91f6e;
  box-sizing: border-box;
  box-shadow: 0 0 20px 2px #f9066bf7;
  transform:scale(0.9);
   
}
