grid-template

版本：CSS3

grid-template，CSS属性简写，用以定义网格中行、列与分区。

示例

/* 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;

浏览器支持

IE不支持grid-template，其余浏览器都支持grid-template

语法

grid-template:none| <grid-template-rows>/ <grid-template-columns>|[<line-names>?<string><track-size>?<line-names>?]+[ /<explicit-track-list>]?

取值

• 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。
