变换比例略微推动 Font Awesome 图标

Question

我在带有display: flex 的父div 中有一个Font Awesome 图标，它本身位于display: flex 的容器div 中。

当我在悬停时尝试 transform: scale(1.2) 时，它会稍微推动元素：

https://jsfiddle.net/Daniel_Knights/gptyo3be/5/

.container {
  display: flex;
  justify-content: center;
  align-items: center;
  width: 100%;
  height: 100%;
}

.parent {
  display: flex;
  justify-content: center;
  align-items: center;
  width: 100px;
  height: 100px;
}

i {
  cursor: pointer;
  transition: transform 0.2s;
}

i:hover {
  transform: scale(1.2);
}

<link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.13.0/css/all.css">

<div class="container">
  <div class="parent">
    <i class="fa fa-eye" id="single-item-eye"></i>
  </div>
</div>

任何想法为什么会这样？

Answer 1

改用 SVG 版本就不会出现问题。缩放 SVG 比缩放文本更好：

.container {
  display: flex;
  justify-content: center;
  align-items: center;
  width: 100%;
  height: 100%;
}

.parent {
  display: flex;
  justify-content: center;
  align-items: center;
  width: 100px;
  height: 100px;
}

svg {
  cursor: pointer;
  transition: transform 0.2s;
}

svg:hover {
  transform: scale(1.2);
}

<script  src="https://use.fontawesome.com/releases/v5.13.0/js/all.js"></script>

<div class="container">
  <div class="parent">
    <i class="fa fa-eye" id="single-item-eye"></i>
  </div>
</div>
