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

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%
