css – svg中的中心组元素

我正在尝试使用svg图作为放大页面过渡.这个html页面有一个SVG元素,它将覆盖整个屏幕,其中是一个< g>元素,我希望在其父svg元素的中间水平和垂直居中,因此在视口的中间.

我尝试过使用CSS(绝对定位,translateX()等)无济于事.
它可能吗？

这是一个prototype on codepen.

解决方法

看起来你只需要翻译< g>保存路径,您可以使用javascript动态计算和执行

body{
  width:100%;
  height:100%;
  overflow:hidden;
}
.logo{
    position:relative;
      display:block;
    margin:auto;
    border:3px solid black;
    width:600px;
    height:600px;
}
#twitter-g{
    transform: translate(200px,200px);
}
.twitter {

    transform-origin: center center;
    animation: kaboom 5s linear infinite;
}

<svg class="logo">
    <g id="Page-1" stroke="none" stroke-width="1" fill="none" fill-rule="evenodd" style="border:1px solid grey;">
        <g id="twitter-g" fill="#000000" class="container">
