grid
grid CSS 屬性是一個簡寫屬性,可以在一個宣告中設定所有顯式和隱式網格屬性。
使用 grid 時,你可以使用 grid-template-rows 或 grid-template-columns 指定一個軸,然後使用隱式網格屬性指定內容應如何在另一個軸上自動重複:grid-auto-rows、grid-auto-columns 和 grid-auto-flow。
試一試
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: rgb(0 0 255 / 0.2);
border: 3px solid blue;
}
#example-element :nth-child(2) {
background-color: rgb(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: rgb(94 255 0 / 0.2);
border: 3px solid green;
grid-column: auto / span 2;
}
注意: 未指定的子屬性將被設定為其初始值,這和普通簡寫屬性的行為一致。另外,此簡寫屬性不會重置 gutter 屬性。
構成屬性
此屬性是以下 CSS 屬性的簡寫:
語法
/* <'grid-template'> values */
grid: none;
grid: "a" 100px "b" 1fr;
grid: [line-name1] "a" 100px [line-name2];
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: revert;
grid: revert-layer;
grid: unset;
值
<'grid-template'>-
定義
grid-template,包括grid-template-columns、grid-template-rows和grid-template-areas。 <'grid-template-rows'> / [ auto-flow && dense? ] <'grid-auto-columns'>?-
透過
grid-template-rows屬性顯式設定行軌道(並將grid-template-columns屬性設定為none),並透過grid-auto-columns指定如何自動重複列軌道(並將grid-auto-rows設定為auto),來設定自動流。grid-auto-flow也會相應地設定為column,如果指定了dense,則也會一併設定。所有其他的
grid子屬性都會被重置為其初始值。 [ auto-flow && dense? ] <'grid-auto-rows'>? / <'grid-template-columns'>-
透過
grid-template-columns屬性顯式設定列軌道(並將grid-template-rows屬性設定為none),並透過grid-auto-rows指定如何自動重複行軌道(並將grid-auto-columns設定為auto),來設定自動流。grid-auto-flow也會相應地設定為row,如果指定了dense,則也會一併設定。所有其他的
grid子屬性都會被重置為其初始值。
