Angular Material - 布局

布局指令

布局指令用于容器元素，用于指定其子元素的布局方向。以下是布局指令的可赋值值：

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，例如布局根据设备屏幕尺寸自动更改，可以使用下表中列出的布局 API 来设置设备视图宽度的布局方向。

序号	API & 断点覆盖默认值时的设备宽度
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

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。它定义了元素如何相对于其父容器和容器内的其他元素调整其大小的方式。以下是 flex 指令的可赋值值：

5 的倍数 - 5、10、15 ... 100
33 - 33%
66 - 66%
