## Layout 布局
|
||
|
||
提供了`van-row`和`van-col`两个组件来进行行列布局
|
||
|
||
### 使用指南
|
||
``` javascript
|
||
import { Row, Col } from 'vant';
|
||
|
||
Vue.use(Row).use(Col);
|
||
```
|
||
|
||
### 代码演示
|
||
|
||
#### 基本用法
|
||
|
||
Layout 组件提供了`24列栅格`，通过在`Col`上添加`span`属性设置列所占的宽度百分比
|
||
此外，添加`offset`属性可以设置列的偏移宽度，计算方式与 span 相同
|
||
|
||
```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-row>
|
||
|
||
<van-row>
|
||
<van-col offset="12" span="12">offset: 12, span: 12</van-col>
|
||
</van-row>
|
||
```
|
||
|
||
#### 设置列元素间距
|
||
|
||
通过`gutter`属性可以设置列元素之间的间距，默认间距为 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>
|
||
```
|
||
|
||
#### Flex 布局
|
||
|
||
将 `type` 属性设置为 flex 可以启用 flex 布局，便于进行灵活的对齐
|
||
|
||
```html
|
||
<!-- 左对齐 -->
|
||
<van-row type="flex">
|
||
<van-col span="6">span: 6</van-col>
|
||
<van-col span="6">span: 6</van-col>
|
||
<van-col span="6">span: 6</van-col>
|
||
</van-row>
|
||
|
||
<!-- 居中 -->
|
||
<van-row type="flex" justify="center">
|
||
<van-col span="6">span: 6</van-col>
|
||
<van-col span="6">span: 6</van-col>
|
||
<van-col span="6">span: 6</van-col>
|
||
</van-row>
|
||
|
||
<!-- 右对齐 -->
|
||
<van-row type="flex" justify="end">
|
||
<van-col span="6">span: 6</van-col>
|
||
<van-col span="6">span: 6</van-col>
|
||
<van-col span="6">span: 6</van-col>
|
||
</van-row>
|
||
|
||
<!-- 两端对齐 -->
|
||
<van-row type="flex" justify="space-between">
|
||
<van-col span="6">span: 6</van-col>
|
||
<van-col span="6">span: 6</van-col>
|
||
<van-col span="6">span: 6</van-col>
|
||
</van-row>
|
||
|
||
<!-- 每个元素的两侧间隔相等 -->
|
||
<van-row type="flex" justify="space-around">
|
||
<van-col span="6">span: 6</van-col>
|
||
<van-col span="6">span: 6</van-col>
|
||
<van-col span="6">span: 6</van-col>
|
||
</van-row>
|
||
```
|
||
