CSS-多行文本垂直居中

在css中的单行文本垂直居中一般常见设置height和line-height相同即可。但是如果多行，文本就会溢出。

特意总结了多行文本垂直居中的办法

1. 使用table-cell

<style>
.single{
  height: 80px;
  border: 1px solid red;
  display: table-cell;
   200px;
  vertical-align: middle;
}
</style>
<div class="single">
  table-cell&vertical-align方式实现
</div>

2. 父元素设置line-height，子元素设置vertical-align

<style>
.single2{
   200px;
  height: 200px;
  border: 1px solid red;
  line-height: 200px;
}
.single2 span{
  display: inline-block;
  line-height: 20px;
  vertical-align: middle;
}
</style>
<div class="single2">
  <span>line-height&vertical-align方式实现</span>
</div>

3. 定位+CSS3

<style>
.single3{
  height: 200px;
  line-height: 200px;
  position: relative;
  border: 1px solid red;
}
.single3 span{
  position: absolute;
  top: 50%;
  transform: translateY(-50%);
  line-height: 20px;
}
</style>
<div class="single3">
  <span>定位&动画实现(测试文字测试文字测试文字测试文字测试文字)</span>
</div>

4. table-cell

<style>
li{
  list-style: none;
  display: flex;
  height: 80px;
}
.left{
   30%;
  float: left;
  display: table;
  height: 100%;
}
.left>div{
  display: table-cell;
  vertical-align: middle;
  text-align: center;
}
.right{
   70%;
  float: left;
  border: 1px solid #ccc;
  background: rgba(0,0,0,0.8);
  box-sizing: border-box;
  margin-right: 30px;
}
</style>
<ul>
  <li>
    <div class="left">
      <div>黄焖鸡米饭</div>
    </div>
    <div class="right"></div>
  </li>
  <li>
    <div class="left">
      <div>鸡公煲</div>
    </div>
    <div class="right"></div>
  </li>
  <li>
    <div class="left">
      <div>黄焖鸡米饭（超级辣）</div>
    </div>
    <div class="right"></div>
  </li>
</ul>
