## Usage
|
||
|
||
### Basic Usage
|
||
|
||
Layout are based on 24-column. The attribute `span` in `Col` means the number of column the grid spans. Of course, You can use `offset` attribute to set number of spacing on the left side of the grid.
|
||
|
||
```html
|
||
<van-row>
|
||
<van-col span="8">span: 8</van-col>
|
||
<van-col span="8">span: 8</van-col>
|
||
<van-col span="8">span: 8</van-col>
|
||
</van-row>
|
||
|
||
<van-row>
|
||
<van-col span="4">span: 4</van-col>
|
||
<van-col span="10" offset="4">offset: 4, span: 10</van-col>
|
||
<van-col span="6">span: 6</van-col>
|
||
</van-row>
|
||
|
||
<van-row>
|
||
<van-col offset="12" span="12">offset: 12, span: 12</van-col>
|
||
</van-row>
|
||
```
|
||
|
||
### Column Spacing
|
||
|
||
Set grid spacing using `gutter` attribute. The default value is 0
|
||
|
||
```html
|
||
<van-row gutter="20">
|
||
<van-col span="8">span: 8</van-col>
|
||
<van-col span="8">span: 8</van-col>
|
||
<van-col span="8">span: 8</van-col>
|
||
</van-row>
|
||
```
|
||
|
||

||
