row-gap

row-gap 该 CSS 属性用来设置行元素之间的间隙（gutter）大小。

规范的早期版本将此属性命名为 grid-row-gap，为了保持与旧网站的兼容性，浏览器仍然会将 grid-row-gap 视为 row-gap 的别名。

尝试一下

语法

css
/* <length> 值 */
row-gap: 20px;
row-gap: 1em;

row-gap: 10%;

/* 全局值 */
row-gap: inherit;
row-gap: initial;
row-gap: revert;
row-gap: revert-layer;
row-gap: unset;
