gap (grid-gap)
CSS gap
属性是用来设置网格行与列之间的间隙(gutters),该属性是 row-gap
和 column-gap
的简写形式。
尝试一下
语法
css
/* One <length> value */
gap: 20px;
gap: 1em;
gap: 3vmin;
gap: 0.5cm;
/* One <percentage> value */
gap: 16%;
gap: 100%;
/* Two <length> values */
gap: 20px 10px;
gap: 1em 0.5em;
gap: 3vmin 2vmax;
gap: 0.5cm 2mm;
/* One or two <percentage> values */
gap: 16% 100%;
gap: 21px 82%;
/* calc() values */
gap: calc(10% + 20px);
gap: calc(20px + 10%) calc(10% - 5px);
/* Global values */
gap: inherit;
gap: initial;
gap: revert;
gap: revert-layer;
gap: unset;
该属性用来表示 <'row-gap'>
和 <'column-gap'>
的值(<'column-gap'>
是可选的)。假如 <'column-gap'>
缺失的话,则会被设置成跟 <'row-gap'>
一样的的值。
<'row-gap'>
和 <'column-gap'>
都可以用 <length>
或者 <percentage>
来表示。
值
<length>
-
网格线之间的间隙宽度。
<percentage>
-
网格线直接的间隙宽度,相对网格容器的百分比。
