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-rows、grid-template-columns 和 grid-template-areas，
隐式网格属性 grid-auto-rows、grid-auto-columns 和 grid-auto-flow，
间距属性 grid-column-gap 和 grid-row-gap。
尝试一下
grid: auto-flow / 1fr 1fr 1fr;
grid: auto-flow dense / 40px 40px 1fr;
grid: repeat(3, 80px) / auto-flow;
<section class="default-example" id="default-example">
<div class="example-container">
<div class="transition-all" id="example-element">
<div>One</div>
<div>Two</div>
<div>Three</div>
</div>
</div>
</section>
#example-element {
border: 1px solid #c5c5c5;
display: grid;
grid-gap: 10px;
width: 200px;
}
#example-element :nth-child(1) {
background-color: rgba(0, 0, 255, 0.2);
border: 3px solid blue;
}
#example-element :nth-child(2) {
background-color: rgba(255, 0, 200, 0.2);
border: 3px solid rebeccapurple;
grid-column: auto / span 3;
grid-row: auto / span 2;
}
#example-element :nth-child(3) {
background-color: rgba(94, 255, 0, 0.2);
border: 3px solid green;
grid-column: auto / span 2;
}
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;
值
<'grid-template'>-
定义了
grid-template，其包含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。
