css - 在不裁剪的情况下仅对 SVG 中的一条路径进行动画处理

Question

我正在为我的 Logo 使用 SVG，我想给其中一个字母一个下推效果:

body {
  background: skyblue;
}

@-webkit-keyframes push {
  0%,
  25%,
  75%,
  100% {
    -webkit-transform: translateY(0);
    transform: translateY(0);
  }
  50% {
    -webkit-transform: translateY(8px);
    transform: translateY(8px);
  }
}

#Path_9-2 {
  -webkit-animation: push 2s;
  animation: push 2s;
  -webkit-animation-iteration-count: infinite;
  animation-iteration-count: infinite;
}

如您所见，“o”在被向下推时被裁剪了。尝试使用 overflow: visible 并增加高度，但这没有帮助。

Answer 1

我已经删除了过滤器的大小和位置。此外，我正在按照您的预期使用 svg{overflow:visible} 。被切断的是形体的影子。请看一下。

body{background:skyBlue;}

 @-webkit-keyframes push {
	0%,
	25%,
	75%,
	100% {
		-webkit-transform: translateY(0);
		        transform: translateY(0);
	}
	50% {
		-webkit-transform: translateY(8px);
		        transform: translateY(8px);
	}
}
#Path_9-2{

    -webkit-animation: push 2s;
    animation: push 2s;
    -webkit-animation-iteration-count: infinite;
    animation-iteration-count: infinite;
}


svg{overflow:visible}
