grid-template
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since 2017年10月.

尝试一下
grid-template: "a a a" 40px "b c c" 40px "b c c" 40px / 1fr 1fr 1fr;grid-template: "b b a" auto "b b c" 2ch "b b c" 1em / 20% 20px 1fr;grid-template: "a a ." minmax(50px, auto) "a a ." 80px "b b c" auto / 2em 3em auto;<section> <div> <div> <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; grid-area: a;}#example-element :nth-child(2) { background-color: rgba(255, 0, 200, 0.2); border: 3px solid rebeccapurple; grid-area: b;}#example-element :nth-child(3) { background-color: rgba(94, 255, 0, 0.2); border: 3px solid green; grid-area: c;}所简写属性:grid-template-rows、grid-template-columns与grid-template-areas。
语法
/* 值为关键词 */grid-template: none;/* 为 grid-template-rows / grid-template-columns */grid-template: 100px 1fr / 50px 1fr;grid-template: auto 1fr / auto 1fr auto;grid-template: [linename] 100px / [columnname1] 30% [columnname2] 70%;grid-template: fit-content(100px) / fit-content(40%);/* 为 grid-template-areas grid-template-rows / grid-template-column */grid-template: "a a a" "b b b";grid-template: "a a a" 20% "b b b" auto;grid-template: [header-top] "a a a" [header-bottom] [main-top] "b b b" 1fr [main-bottom] / auto 1fr auto;/* 为全局值 */grid-template: inherit;grid-template: initial;grid-template: unset;可设值
none关键词,设上文“所简写属性”为
none,即恢复默认设置。行列隐式生成,grid-auto-rows与grid-auto-columns定其尺寸。<'grid-template-rows'> / <'grid-template-columns'>指定
grid-template-rows与grid-template-columns之值,并设grid-template-areas为none。[ <line-names>? <string> <track-size>? <line-names>? ]+ [ / <explicit-track-list> ]?设
grid-template-areas为列得<string>、grid-template-columns为<explicit-track-list>(默认为none)、grid-template-rows为<track-size>(默认为auto)并拼接尺寸前后所定义之行。注:轨道被用以与“ASCII art”(即字符画,此处指
<string>)中行列逐一视觉对齐,故<explicit-track-list>中不允许repeat()。
注:grid可如此用,但将重置隐式网格属性。Usegrid (as opposed togrid-template) to prevent these values from cascading in seperately.
