Grid栅格

24 栅格系统。

设计理念#

grid design

在多数业务情况下,Ant 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。

从堆叠到水平排列。

使用单一的一组 RowCol 栅格组件,就可以创建一个基本的栅格系统,所有列(Col)必须放在 Row 内。

      <Col span={24}>col</Col>

栅格常常需要和间隔进行配合,你可以使用 Rowgutter 属性,我们推荐使用 (16+8n)px 作为栅格间隔(n 是自然数)。

如果要支持响应式,可以写成 { xs: 8, sm: 16, md: 24, lg: 32 }

如果需要垂直间距,可以写成数组形式 [水平间距, 垂直间距] [16, { xs: 8, sm: 16, md: 24, lg: 32 }]

数组形式垂直间距在 3.24.0 之后支持。

列偏移。

使用 offset 可以将列向右侧偏。例如,offset={4} 将元素向右侧偏移了 4 个列(column)的宽度。
