Grid栅格
24 栅格系统。
设计理念#
在多数业务情况下,Infra Design 需要在设计区域内解决大量信息收纳的问题,因此在 12 栅格系统的基础上,我们将整个设计建议区域按照 24 等分的原则进行划分。
划分之后的信息区块我们称之为『盒子』。建议横向排列的盒子数量最多四个,最少一个。『盒子』在整个屏幕上占比见上图。设计部分基于盒子的单位定制盒子内部的排版规则,以保证视觉层面的舒适感。
概述#
布局的栅格化系统,我们是基于行(row)和列(col)来定义信息区块的外部框架,以保证页面的每个区域能够稳健地排布起来。下面简单介绍一下它的工作原理:
通过
row
在水平方向建立一组column
(简写 col)。你的内容应当放置于
col
内,并且,只有col
可以作为row
的直接元素。栅格系统中的列是指 1 到 24 的值来表示其跨越的范围。例如,三个等宽的列可以使用
<Col span={8} />
来创建。如果一个
row
中的col
总和超过 24,那么多余的col
会作为一个整体另起一行排列。
我们的栅格化系统基于 Flex 布局,允许子元素在父节点内的水平对齐方式 - 居左、居中、居右、等宽排列、分散排列。子元素与子元素之间,支持顶部对齐、垂直居中对齐、底部对齐的方式。同时,支持使用 order 来定义元素的排列顺序。
布局是基于 24 栅格来定义每一个『盒子』的宽度,但不拘泥于栅格。

Infra Design 的布局组件若不能满足你的需求,你也可以直接使用社区的优秀布局组件:
Row#
成员 | 说明 | 类型 | 默认值 | 版本 |
---|---|---|---|---|
align | 垂直对齐方式 | top | middle | bottom | top | |
gutter | 栅格间隔,可以写成像素值或支持响应式的对象写法来设置水平间隔 { xs: 8, sm: 16, md: 24}。或者使用数组形式同时设置 [水平间距, 垂直间距] | number | object | array | 0 | |
justify | 水平排列方式 | start | end | center | space-around | space-between | space-evenly | start | |
wrap | 是否自动换行 | boolean | true | 4.8.0 |
Col#
成员 | 说明 | 类型 | 默认值 | 版本 |
---|---|---|---|---|
flex | flex 布局属性 | string | number | - | |
offset | 栅格左侧的间隔格数,间隔内不可以有栅格 | number | 0 | |
order | 栅格顺序 | number | 0 | |
pull | 栅格向左移动格数 | number | 0 | |
push | 栅格向右移动格数 | number | 0 | |
span | 栅格占位格数,为 0 时相当于 display: none | number | - | |
xs | 屏幕 < 576px 响应式栅格,可为栅格数或一个包含其他属性的对象 | number | object | - | |
sm | 屏幕 ≥ 576px 响应式栅格,可为栅格数或一个包含其他属性的对象 | number | object | - | |
md | 屏幕 ≥ 768px 响应式栅格,可为栅格数或一个包含其他属性的对象 | number | object | - | |
lg | 屏幕 ≥ 992px 响应式栅格,可为栅格数或一个包含其他属性的对象 | number | object | - | |
xl | 屏幕 ≥ 1200px 响应式栅格,可为栅格数或一个包含其他属性的对象 | number | object | - | |
xxl | 屏幕 ≥ 1600px 响应式栅格,可为栅格数或一个包含其他属性的对象 | number | object | - |
响应式栅格的断点扩展自 BootStrap 4 的规则(不包含链接里 occasionally
的部分)。
