grid

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since October 2017.

grid 是一个 CSS 简写属性,可以用来设置以下属性: 显式网格属性 grid-template-rowsgrid-template-columnsgrid-template-areas, 隐式网格属性 grid-auto-rowsgrid-auto-columnsgrid-auto-flow, 间距属性 grid-column-gapgrid-row-gap

尝试一下

备注: 你仅可在一个 grid 属性中声明显式或隐式网格。与其他简写属性同样,若有次级属性未被声明,其将使用初始值。另外,尽管此简写声明无法设置网格的槽(gutter),槽会被该声明重置。

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: unset;

<'grid-template'>

定义了 grid-template,其包含 grid-template-columnsgrid-template-rowsgrid-template-areas

<'grid-template-rows'> / [ auto-flow && dense? ] <'grid-auto-columns'>? 通过 grid-template-rows 属性显式设置行轨道来设置自动流(grid-template-columns 属性设为 none),并通过 grid-auto-columns 明确该如何自动重复列轨道(同时grid-auto-rows属性设为 auto)。grid-auto-flow 属性也被相应的设置为 column,并可附有 dense。

所有其余 grid 次级属性被重置为初始值。

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

通过 grid-template-columns 属性显式设置列轨道来设置自动流(grid-template-rows 属性设为 none),并通过 grid-auto-rows 明确该如何自动重复行轨道(同时grid-auto-columns属性设为 auto)。grid-auto-flow 属性也被相应的设置为 row,并可附有 dense。 所有其余 grid 次级属性被重置为初始值。
