推荐答案

这应该适合您的需求.这是CSS-2D转换技巧.我最近遇到了以下解决方案:

This should fit your needs. It is a CSS-2D-transition trick. I have recently come across the following solution:

* {
  font-family: Arial;
  font-size: 14px;
  -webkit-font-smoothing: antialiased;
  text-rendering: optimizeLegibility;
}

*:after,
*:before {
  content: "";
  display: table;
}

*:after {
  clear: both;
}

.title {
  font-family: Georgia;
  font-size: 36px;
  line-height: 1.25;
  margin-top: 0;
}

.blocks {
  position: relative;
}

.block {
  position: relative;
  display: inline-block;
  float: left;
  width: 200px;
  height: 200px;
  font-weight: bold;
  color: #FFFFFF;
  margin-right: 10px;
  margin-bottom: 10px;
}

.block:first-child {
  background-color: green;
}

.block:nth-child(2) {
  background-color: red;
}

.block:nth-child(3) {
  background-color: blue;
}

.h-center {
  text-align: center;
}

.v-center span {
  position: absolute;
  left: 0;
  right: 0;
  top: 50%;
  transform: translate(0, -50%);
}

<h1 class="title">3 Boxes with different text-align settings.</h1>
<div class="blocks">
  <div class="block h-center">horizontally centered lorem ipsun dolor sit amet</div>
  <div class="block v-center"><span>vertically centered lorem ipsun dolor sit amet lorem ipsun dolor sit amet</span></div>
  <div class="block h-center v-center"><span>horizontally and vertically centered lorem ipsun dolor sit amet</span></div>
</div>

注意:这也适用于:after和:before伪元素.
