解决。这是一个不同的错误，因为图像大小。解决方案很简单：codepen.io/devtips/pen/OPQYav（由 youtube.com/user/DevTipsForDesigners 制作）

.parent {
  border: 3px solid orange;
  height: 400px;
  display: flex;
  flex-direction: column;
  justify-content: space-around;
  align-items: center;
}

.child {
  width: 100px;
  height: 100px;
  background: blueviolet
}

<div class="parent">
  <div class="child"></div>
  <div class="child"></div>
  <div class="child"></div>
</div>
