Grid栅格

24 栅格系统。

设计理念

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 <div nz-col [nzSpan]="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。

  1. import { NzGridModule } from 'ng-zorro-antd/grid';

基础栅格

从堆叠到水平排列。

使用单一的一组 nz-rownz-col 栅格组件,就可以创建一个基本的栅格系统,所有列(nz-col)必须放在 nz-row 内。

  1. import { Component } from '@angular/core';
  2. @Component({
  3. selector: 'nz-demo-grid-basic',
  4. template: `
  5. <div nz-row>
  6. <div nz-col nzSpan="12">col-12</div>
  7. <div nz-col nzSpan="12">col-12</div>
  8. </div>
  9. <div nz-row>
  10. <div nz-col nzSpan="8">col-8</div>
  11. <div nz-col nzSpan="8">col-8</div>
  12. <div nz-col nzSpan="8">col-8</div>
  13. </div>
  14. <div nz-row>
  15. <div nz-col nzSpan="6">col-6</div>
  16. <div nz-col nzSpan="6">col-6</div>
  17. <div nz-col nzSpan="6">col-6</div>
  18. <div nz-col nzSpan="6">col-6</div>
  19. </div>
  20. `
  21. })
  22. export class NzDemoGridBasicComponent {}

区块间隔

栅格常常需要和间隔进行配合,你可以使用 nz-rownzGutter 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, xl: 32, xxl: 32 }

  1. import { Component } from '@angular/core';
  2. @Component({
  3. selector: 'nz-demo-grid-gutter',
  4. template: `
  5. <nz-divider nzOrientation="left" nzText="Horizontal"></nz-divider>
  6. <div nz-row [nzGutter]="16">
  7. <div nz-col class="gutter-row" [nzSpan]="6"><div class="inner-box">col-6</div></div>
  8. <div nz-col class="gutter-row" [nzSpan]="6"><div class="inner-box">col-6</div></div>
  9. <div nz-col class="gutter-row" [nzSpan]="6"><div class="inner-box">col-6</div></div>
  10. <div nz-col class="gutter-row" [nzSpan]="6"><div class="inner-box">col-6</div></div>
  11. </div>
  12. <nz-divider nzOrientation="left" nzText="Responsive"></nz-divider>
  13. <div nz-row [nzGutter]="{ xs: 8, sm: 16, md: 24, lg: 32 }">

左右偏移

列偏移。

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

  1. import { Component } from '@angular/core';
  2. @Component({
  3. selector: 'nz-demo-grid-offset',
  4. template: `
  5. <div nz-row>
  6. <div nz-col nzSpan="8">
  7. col-8
  8. </div>
  9. <div nz-col nzSpan="8" nzOffset="8">
  10. col-8
  11. </div>
  12. </div>
  13. <div nz-row>
  14. <div nz-col nzSpan="6" nzOffset="6">
  15. col-6 col-offset-6
  16. </div>
  17. <div nz-col nzSpan="6" nzOffset="6">
  18. col-6 col-offset-6
  19. </div>
  20. </div>
  21. <div nz-row>
  22. <div nz-col nzSpan="12" nzOffset="6">
  23. col-12 col-offset-6
  24. </div>
  25. </div>
  26. `
  27. })
  28. export class NzDemoGridOffsetComponent {}

栅格排序

列排序。

通过使用 nzPushnzPull 类就可以很容易的改变列(column)的顺序。

  1. import { Component } from '@angular/core';
  2. @Component({
  3. selector: 'nz-demo-grid-sort',
  4. template: `
  5. <div nz-row>
  6. <div nz-col [nzSpan]="18" [nzPush]="6">
  7. col-18 col-push-6
  8. </div>
  9. <div nz-col [nzSpan]="6" [nzPull]="18">
  10. col-6 col-pull-18
  11. </div>
  12. </div>
  13. `
  14. })
  15. export class NzDemoGridSortComponent {}

Flex 填充

nz-col 提供 nzFlex 属性以支持填充。

  1. import { Component } from '@angular/core';
  2. @Component({
  3. selector: 'nz-demo-grid-flex-stretch',
  4. template: `
  5. <div>

  11. <p>Fill rest</p>
  12. <div nz-row>
  13. <div nz-col nzFlex="100px">100px</div>
  14. <div nz-col nzFlex="auto">Fill Rest</div>

  27. }
  28. `
  29. ]
  30. })
  31. export class NzDemoGridFlexStretchComponent {}

响应式布局

参照 Bootstrap 的 响应式设计,预设五个响应尺寸:xs``sm``md``lg``xl``xxl

  1. import { Component } from '@angular/core';
  2. @Component({
  3. selector: 'nz-demo-grid-responsive',
  4. template: `
  5. <div nz-row>
  6. <div nz-col nzXs="2" nzSm="4" nzMd="6" nzLg="8" nzXl="10">
  7. Col
  8. </div>
  9. <div nz-col nzXs="20" nzSm="16" nzMd="12" nzLg="8" nzXl="4">
  10. Col
  11. </div>
  12. <div nz-col nzXs="2" nzSm="4" nzMd="6" nzLg="8" nzXl="10">
  13. Col
  14. </div>
  15. </div>
  16. `
  17. })
  18. export class NzDemoGridResponsiveComponent {}

Grid栅格 - 图10

其他属性的响应式

span``pull``push``offset``order 属性可以通过内嵌到 nzXs``nzSm``nzMd``nzLg``nzXl``nzXXl 属性中来使用。

其中 nzXs="6" 相当于 [nzXs]="{ span: 6 }"

  1. import { Component } from '@angular/core';
  2. @Component({
  3. selector: 'nz-demo-grid-responsive-more',
  4. template: `
  5. <div nz-row>
  6. <div nz-col [nzXs]="{ span: 5, offset: 1 }" [nzLg]="{ span: 6, offset: 2 }">
  7. Col
  8. </div>
  9. <div nz-col [nzXs]="{ span: 11, offset: 1 }" [nzLg]="{ span: 6, offset: 2 }">
  10. Col
  11. </div>
  12. <div nz-col [nzXs]="{ span: 5, offset: 1 }" [nzLg]="{ span: 6, offset: 2 }">
  13. Col
  14. </div>
  15. </div>
