grid - 隐式网格

当网格项目确认在显式网格之外时就会创建隐性网格,当没有足够的空间或者显式的网格轨道来设置网格项目,此时网格项目就会自动创建隐式网格.

 

隐式网格可以定义:grid-auto-rowsgrid-auto-columnsgrid-auto-flow属性

 

1.在这个例子中我们只定义了一行(轨道),所以item1item2的高都是70px

第二行(轨道)自动创建了item3item4空间。grid-auto-rows定义隐式网格中的行(轨道)的大小,因此item3item4的高度是140px

 

 1 <view class="grid">
 2   <view class='item1'>1</view>
 3   <view class='item'>2</view>
 4   <view class='item'>3</view>
 5   <view class='item'>4</view>
 6   <!-- <view class='item'>5</view>
 7   <view class='item'>6</view>
 8   <view class='item'>7</view>
 9   <view class='item'>8</view>
10   <view class='item'>9</view> -->
11 </view>
View Code

 

 1 page {
 2   color: #fff;
 3   font-size: 16px;
 4 }
 5 
 6 .grid {
 7   /* padding: 1%; */
 8   display: grid;
 9   grid-gap: 1px;
10   line-height: 100px;
11   grid-template-rows: 70px;
12   grid-template-columns: repeat(2, 1fr);
13   grid-auto-rows: 140px;
14 }
15 
16 .item1 {
17   
18 }
19 
20 .item {
21   text-align: center;
22   background-color: #d94a6a;
23 }
24 
25 .item1 {
26   text-align: center;
27   /* line-height: 300px; */
28   background-color: #1aa034;
29 }
View Code

 

 

2.更改默认流方向(默认row)

 

grid-auto-flow: column;

 

 1 <view class="grid">
 2   <view class='item1'>1</view>
 3   <view class='item'>2</view>
 4   <view class='item'>3</view>
 5   <view class='item'>4</view>
 6   <!-- <view class='item'>5</view>
 7   <view class='item'>6</view>
 8   <view class='item'>7</view>
 9   <view class='item'>8</view>
10   <view class='item'>9</view> -->
11 </view>
View Code
 1 page {
 2   color: #fff;
 3   font-size: 16px;
 4 }
 5 
 6 .grid {
 7   /* padding: 1%; */
 8   display: grid;
 9   grid-gap: 1px;
10   line-height: 100px;
11   grid-template-rows: 70px;
12   grid-template-columns: repeat(2, 1fr);
13   grid-auto-rows: 140px;
14   grid-auto-flow: column;
15 }
16 
17 .item1 {
18   
19 }
20 
21 .item {
22   text-align: center;
23   background-color: #d94a6a;
24 }
25 
26 .item1 {
27   text-align: center;
28   /* line-height: 300px; */
29   background-color: #1aa034;
30 }
View Code

 

 row

 

 column

 

3.在这个例子中,我们只定义了前两列的轨道尺寸。item1的尺寸是30pxitem2的尺寸是60px

 

 1 page {
 2   color: #fff;
 3   font-size: 16px;
 4 }
 5 
 6 .grid {
 7   /* padding: 1%; */
 8   display: grid;
 9   grid-gap: 1px;
10   line-height: 100px;
11   grid-template-columns: 30px 60px;
12   grid-auto-flow: column;
13   grid-auto-columns: 1fr;
14 }
15 
16 .item1 {
17 }
18 
19 .item {
20   text-align: center;
21   background-color: #d94a6a;
22 }
23 
24 .item1 {
25   text-align: center;
26   /* line-height: 300px; */
27   background-color: #1aa034;
28 }
View Code

 

 

 

使用grid-auto-flow:column自动创建了隐式网格,用来放置item3item4item5,并且这三个列(轨道)的尺寸由grid-auto-columns来定义
