 ## 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。
