CSS Grid Layout 起初是用 grid-row-gap 属性来定义的，目前逐渐被 row-gap 替代。但是，为了兼容那些不支持 row-gap 属性的浏览器，你需要像上面的例子一样使用带有前缀的属性。

语法

/* <length> values */
row-gap: 20px;
row-gap: 1em;
row-gap: 3vmin;
row-gap: 0.5cm;

/* <percentage> value */
row-gap: 10%;

/* Global values */
row-gap: inherit;
row-gap: initial;
row-gap: unset;

值

<length-percentage>

表示行之间的间隔宽度。 <percentage> 表示相对栅格容器的百分比。

正式语法

normal | <length-percentage>
where 
<length-percentage> = <length> | <percentage>

示例

Flex布局

这是一个实验中的功能
此功能某些浏览器尚在开发中，请参考浏览器兼容性表格以得到在不同浏览器中适合使用的前缀。由于该功能对应的标准文档可能被重新修订，所以在未来版本的浏览器中该功能的语法和行为可能随之改变。

HTML

<div id="flexbox">
  <div></div>
  <div></div>
  <div></div>
  <div></div>
  <div></div>
  <div></div>
</div>

CSS

#flexbox {
  display: flex;
  flex-wrap: wrap;
  width: 300px;
  row-gap: 20px;
}

#flexbox > div {
  background-color: lime;
  flex: 1 1 auto;
  width: 100px;
  height: 50px;

}

结果

Grid布局

HTML

<div id="grid">
  <div></div>
  <div></div>
  <div></div>
</div>

CSS

#grid {
  display: grid;
  height: 200px;
  grid-template-columns: 200px;
  grid-template-rows: repeat(3, 1fr);
  row-gap: 20px;
}

#grid > div {
  background-color: lime;
}

结果
