鼠标离开时悬停动画抖动（使用CSS过渡和变换）

Question

我正在使用CSS过渡和变换来缩放SVG中圆元素的大小。然而，当我的鼠标离开元素时，似乎有一个抽搐动作。

<svg viewBox="-5 -5 50 50">
    <circle cx="20" cy="20" r="20" />
    <path d="M20,31 C15.4189994,27.2225585 12.5023327,24.2225585 11.25,22 C10.2743515,20.6156479 10,19.6181623 10,18.1428571 C10,15.5113854 12.4883456,13 15,13 C17.3176009,13 18.9621484,13.8491346 20,15.5714286 C21.0382977,13.8491346 22.6828452,13 25,13 C27.5116544,13 30,15.5113854 30,18.1428571 C30,19.6181623 29.7256485,20.6156479 28.75,22 C27.497816,24.2225585 24.5811493,27.2225585 20,31 Z" />

CSS：

circle {
    fill: #EEE;
    -webkit-transition: -webkit-transform .1s ease-in-out; 
    -moz-transition: -moz-transform .1s ease-in-out; 
}

path {
    fill: #CCC;
}

svg:hover circle {
    transform: scale(1.15);
    -ms-transform: scale(1.15);
    -webkit-transform: scale(1.15);
    transform-origin: center center;
    -webkit-transform-origin: center center;
    -ms-transform-origin: center center;
}

Answer 1

将transform-origin属性移动到circle元素的一般规则中，这样只有在:hover时它才能处理它的位置：

circle {
  fill: #EEE;
  -webkit-transition: -webkit-transform .1s ease-in-out; 
  -moz-transition: -moz-transform .1s ease-in-out;
  transform-origin: center center;
  -webkit-transform-origin: center center;
  -ms-transform-origin: center center;
}

path {
  fill: #CCC;
}

svg:hover circle {
  transform: scale(1.15);
  -ms-transform: scale(1.15);
  -webkit-transform: scale(1.15);
}

<svg viewBox="-5 -5 50 50">
  <circle cx="20" cy="20" r="20" />
