我需要围绕其中心zoom SVG(引用为<use>)，这也会影响父对象的大小.(父级必须绝对定位)
设置如下所示:
<div class="parent">
<svg class="visual" viewBox="0 0 30 30" width="30">
<use href="#ref" />
</svg>
</div>
try 了以下附言:
我也试着将原点平移到中心，但SVG似乎不是这样工作的(大多数是截断的).
目标是在不影响父样式(如边框)但影响父大小的情况下，在中心zoom SVG引用.
可以将齿轮大小从中心绝对位置更改为top: 50%; left: 50%;，并在X轴和Y轴上平移元素-50%.这里有一个例子，SVG在悬停时改变了它的大小:
.container {
position: relative;
width: 200px;
height: 200px;
background-color: green;
}
.element {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
background-color: orange;
border: 3px solid red;
}
.visual {
display: block;
width: 30px;
height: 30px;
transition: width .5s, height .5s;
}
.element:hover .visual {
width: 100px;
height: 100px;
}<svg style="display: none;">
