布局指令

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 -

row - 项目水平排列，max-height = 100％，max-width是容器中项目的宽度。
column - 项目垂直排列，max-width = 100％，max-height是容器中项目的高度。

对于响应式设计（例如根据设备屏幕大小自动更改布局），下表中列出的布局API可用于设置具有视图宽度的设备的布局方向。

Sr.No	断点覆盖默认值时的API和设备宽度
1	layout 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 宽度> = 600px
4	layout-sm 600px <=宽度<960px
5	layout-gt-sm 宽度> = 960px
6	layout-md 960px <=宽度<1280px
7	layout-gt-md 宽度> = 1280px
8	layout-lg 1280px <=宽度<1920px
9	layout-gt-lg 宽度> = 1920px
10	layout-xl 宽度> = 1920px

例子 (Example)

以下示例显示了layout指令的使用以及布局的用法。

Flex指令

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指令的可分配值 -

multiples of 5 - 5,10,15 ... 100的multiples of 5
33 - 33％
66 - 66％

例子 (Example)

以下示例显示了flex指令的使用以及flex的用法。
