容器元素上的布局指令用于指定其子元素的布局方向.以下是布局指令的可分配值 :
行 : 项目水平排列，最大高度= 100％，最大宽度是容器中项目的宽度.
列 : 项目垂直排列，最大宽度= 100％，最大高度是容器中项目的高度.
对于响应根据设备屏幕大小自动更改布局等设计，下表中列出的布局API可用于设置视图宽度设备的布局方向.
| Sr.No | API&断点覆盖默认值时的设备宽度 |
|---|---|
| 1 | 布局 设置默认布局方向，除非被另一个断点覆盖. |
| 2 | layout-xs 宽度< 600px |
| 3 | layout-gt-xs width> = 600px |
| 4 | layout-sm 600px< = width< 960px |
| 5 | layout-gt-sm 宽度> = 960px |
| 6 | layout-md 960px< = width< 1280px |
| 7 | layout-gt-md width> = 1280px |
| 8 | layout-lg 1280px< = width< 1920px |
| 9 | layout-gt-lg width> = 1920px |
| 10 | layout-xl width> = 1920px |
以下示例显示了布局指令的使用以及布局的用法.

容器元素上的flex指令用于自定义元素的大小和位置。 它定义了元素相对于其父容器和容器中其他元素的大小调整方式。 以下是flex指令的可赋值:
5:5,10,15 ......的倍数
33 : 33%
66: 66%
以下示例显示了flex指令的使用以及flex的用法。
