## Layout 布局
|
||||
|
||||
提供了`van-row`和`van-col`两个组件来进行行列布局。
|

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 { Layout } from 'vant';
|
||||
import { Row, Col } from 'vant';
|
||||
|
||||
Vue.component(Layout.name, Layout);
|
||||
Vue.component(Row.name, Row);
|
||||
Vue.component(Col.name, Col);
|
||||
```
|
||||
|
||||
### 代码演示
|
||||
|
||||
#### 常规用法
|
||||
#### 基本用法
|
||||
|
||||
Layout组件提供了`24列栅格`,通过在`van-col`上添加`span`属性设置列所占的宽度百分比`(span / 24)`;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。

#### 在列元素之间增加间距
|
||||
#### 设置列元素间距
|
||||
|
||||
列元素之间默认间距为0,如果希望在列元素增加相同的间距,可以在`van-row`上添加`gutter`属性来设置列元素之间的间距。
|
||||
通过`gutter`属性可以设置列元素之间的间距,默认间距为 0

||||
