遮罩-仅在特定div上方显示div?

Tan*_*ane 5 html css mask css-animations clip-path

我正在尝试使用HTML和CSS创建“眨眼”动画。

我想要的是,当眨眼时,眼球没有显示出来。

从代码中可以看到,眼睛由4个元素组成。

Div“眼睛”是眼睛所在的容器。

Div“ eye1”和“ eye2”。

Div“眼罩”,具有闪烁效果。

Div“眼球1”和“眼球2”。这些应仅显示在“眼罩”的顶部,而不应显示在“ eye1”和“ eye2”的顶部。

有人可以帮我实现这一目标吗?

您可以像下面这样简化代码并依赖剪辑路径动画:

.eyes {
  padding:20px;
  background: lightblue;
  display: inline-flex;
}

.eyes span{
  width: 80px;
  height: 80px;
  background:grey;
  border-radius:50%;
  margin:10px;
  position:relative;
}
.eyes span:before {
  content:"";
  position:absolute;
  top:0;
  left:0;
  right:0;
  bottom:0;
  background:radial-gradient(black 7px, white 8px);
  animation:blink 0.8s linear infinite alternate;
}
@keyframes blink {
  from {
    clip-path: ellipse(50% 50% at 50% 50%);  
  }
  to {
    clip-path: ellipse(50%  0% at 50% 50%);
  }
}
