构成属性
此属性是以下 CSS 属性的简写：
语法
css
/* Keyword value */
grid-template: none;
/* grid-template-rows / grid-template-columns values */
grid-template: 100px 1fr / 50px 1fr;
grid-template: auto 1fr / auto 1fr auto;
grid-template: [line-name] 100px / [column-name1] 30% [column-name2] 70%;
grid-template: fit-content(100px) / fit-content(40%);
/* grid-template-areas grid-template-rows / grid-template-column values */
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;
/* Global values */
grid-template: inherit;
grid-template: initial;
grid-template: revert;
grid-template: revert-layer;
grid-template: unset;
值
none-
将所有三个长手属性设置为
none，表示没有显式网格。没有命名的网格区域。行和列将隐式生成；它们的尺寸将由grid-auto-rows和grid-auto-columns属性决定。这是默认值。 <'grid-template-rows'> / <'grid-template-columns'>-
将
grid-template-rows和grid-template-columns设置为指定值，并将grid-template-areas设置为none。 [ <line-names>? <string> <track-size>? <line-names>? ]+ [ / <explicit-track-list> ]?-
将
grid-template-areas设置为列出的字符串，将grid-template-rows设置为每个字符串后面的轨道尺寸（对于任何缺失的尺寸，填充auto），并在每个尺寸之前/之后拼接定义的命名线，并将grid-template-columns设置为斜杠后指定的轨道列表（如果未指定，则为none）。注意：在这些轨道列表中不允许使用
repeat()函数，因为轨道旨在与“ASCII 艺术”中的行/列视觉上进行一对一的对齐。
注意：grid 简写接受相同的语法，但也会将隐式网格属性重置为其初始值。使用 grid（而不是 grid-template）可以防止这些值单独级联。
