此功能已得到良好建立，可在许多设备和浏览器版本中使用。它已在所有浏览器中可用，自 2020 年 7 月.

The grid CSS property is a shorthand property that sets all of the explicit and implicit grid properties in a single declaration.

Using grid you specify one axis using grid-template-rows or grid-template-columns, you then specify how content should auto-repeat in the other axis using the implicit grid properties: grid-auto-rows, grid-auto-columns, and grid-auto-flow.

试一试

注意：您未指定的子属性将设置为其初始值，就像简写一样。此外，间距属性不会被此简写重置。

构成属性

此属性是以下 CSS 属性的简写

语法

css
/* <'grid-template'> values */
grid: none;
grid: "a" 100px "b" 1fr;
grid: [linename1] "a" 100px [linename2];
grid: "a" 200px "b" min-content;
grid: "a" minmax(100px, max-content) "b" 20%;
grid: 100px / 200px;
grid: minmax(400px, min-content) / repeat(auto-fill, 50px);

/* <'grid-template-rows'> /
   [ auto-flow && dense? ] <'grid-auto-columns'>? values */
grid: 200px / auto-flow;
grid: 30% / auto-flow dense;
grid: repeat(3, [line1 line2 line3] 200px) / auto-flow 300px;
grid: [line1] minmax(20em, max-content) / auto-flow dense 40%;

/* [ auto-flow && dense? ] <'grid-auto-rows'>? /
   <'grid-template-columns'> values */
grid: auto-flow / 200px;
grid: auto-flow dense / 30%;
grid: auto-flow 300px / repeat(3, [line1 line2 line3] 200px);
grid: auto-flow dense 40% / [line1] minmax(20em, max-content);

/* Global values */
grid: inherit;
grid: initial;
grid: revert;
grid: revert-layer;
grid: unset;

值

<'grid-template'>

定义 grid-template，包括 grid-template-columns、grid-template-rows 和 grid-template-areas.

<'grid-template-rows'> / [ auto-flow && dense? ] <'grid-auto-columns'>?

通过 grid-template-rows 属性（以及 grid-template-columns 属性设置为 none）显式设置行轨迹，并通过 grid-auto-columns（以及将 grid-auto-rows 设置为 auto）指定如何自动重复列轨迹，从而设置自动流。grid-auto-flow 也相应地设置为 column，如果指定了 dense 则为 dense。

所有其他 grid 子属性都重置为其初始值。

[ auto-flow && dense? ] <'grid-auto-rows'>? / <'grid-template-columns'>

通过 grid-template-columns 属性（以及 grid-template-rows 属性设置为 none）显式设置列轨迹，并通过 grid-auto-rows（以及将 grid-auto-columns 设置为 auto）指定如何自动重复行轨迹，从而设置自动流。grid-auto-flow 也相应地设置为 row，如果指定了 dense 则为 dense。

所有其他 grid 子属性都重置为其初始值。
