| 	 * @tutorial https://www.uvui.cn/components/Layout.html | |
| 	 * @property {String | Number}	span		栅格占据的列数,总12等份 (默认 12 )  | |
| 	 * @property {String | Number}	offset		分栏左边偏移,计算方式与span相同 (默认 0 )  | |
| 	 * @property {String}			justify		水平排列方式,可选值为`start`(或`flex-start`)、`end`(或`flex-end`)、`center`、`around`(或`space-around`)、`between`(或`space-between`)  (默认 'start' )  | |
| 	 * @property {String}			align		垂直对齐方式,可选值为top、center、bottom、stretch (默认 'stretch' )  | |
| 	 * @property {String}			textAlign	文字水平对齐方式 (默认 'left' )  | |
| 	 * @property {Object}			customStyle	定义需要用到的外部样式 | |
