In most business situations, Ant Design needs to solve a lot of information storage problems within the design area, so based on 12 Grids System, we divided the design area into 24 aliquots.

We name the divided area 'box'. We suggest four boxes for horizontal arrangement at most, one at least. Boxes are proportional to the entire screen as shown in the picture above. To ensure a high level of visual comfort, we customize the typography inside of the box based on the box unit.

Outline#

In the grid system, we define the frame outside the information area based on row and column, to ensure that every area can have stable arrangement.

Following is a brief look at how it works:

  • Establish a set of column in the horizontal space defined by row (abbreviated col)

  • Your content elements should be placed directly in the col, and only col should be placed directly in row

  • The column grid system is a value of 1-24 to represent its range spans. For example, three columns of equal width can be created by .col-8 (span=8).

  • If the sum of col spans in a row are more than 24, then the overflowing col as a whole will start a new line arrangement.

Flex layout#

Our grid systems support Flex layout to allow the elements within the parent to be aligned horizontally - left, center, right, wide arrangement, and decentralized arrangement. The Grid system also supports vertical alignment - top aligned, vertically centered, bottom-aligned. You can also define the order of elements by using order.

Flex layout uses a 24 grid layout to define the width of each "box", but does not rigidly adhere to the grid layout.

Examples

col-12
col-12
col-8
col-8
col-8
col-6
col-6
col-6
col-6

From the stack to the horizontal arrangement.

You can create a basic grid system by using a single set of Row andCol grid assembly, all of the columns (Col) must be placed in Row.

import { Row, Col } from 'antd';

ReactDOM.render(
  <div>
    <Row>
      <Col span={12}>col-12</Col>
      <Col span={12}>col-12</Col>
    </Row>
    <Row>
      <Col span={8}>col-8</Col>

      <Col span={6}>col-6</Col>
    </Row>
  </div>,

You can use the gutter property of Row as grid spacing, we recommend set it to (16 + 8n) px. (n stands for natural number.)

expand codeexpand code
import { Row, Col } from 'antd';

ReactDOM.render(
  <div className="gutter-example">
    <Row gutter={16}>
      <Col className="gutter-row" span={6}>
        <div className="gutter-box">col-6</div>
      </Col>
      <Col className="gutter-row" span={6}>
        <div className="gutter-box">col-6</div>
      </Col>
      <Col className="gutter-row" span={6}>
        <div className="gutter-box">col-6</div>
      </Col>
      <Col className="gutter-row" span={6}>
        <div className="gutter-box">col-6</div>
      </Col>
    </Row>
  </div>
, mountNode);
.gutter-example .ant-row > div {
  background: transparent;
  border: 0;
}
.gutter-box {
  background: #00A0E9;
  padding: 5px 0;
}
col-8
col-8
col-6 col-offset-6
col-6 col-offset-6
col-12 col-offset-6

Offset can set the column to the right side. For example, using offset = {4} can set the element shifted to the right four columns width.

expand codeexpand code
import { Row, Col } from 'antd';

ReactDOM.render(
  <div>
    <Row>
      <Col span={8}>col-8</Col>
      <Col span={8} offset={8}>col-8</Col>
    </Row>
    <Row>
      <Col span={6} offset={6}>col-6 col-offset-6</Col>
      <Col span={6} offset={6}>col-6 col-offset-6</Col>
    </Row>
    <Row>
      <Col span={12} offset={6}>col-12 col-offset-6</Col>
    </Row>
  </div>,
  mountNode
);
col-18 col-push-6
col-6 col-pull-18

By using push andpull class you can easily change column order.

expand codeexpand code
import { Row, Col } from 'antd';

ReactDOM.render(
  <div>
    <Row>
      <Col span={18} push={6}>col-18 col-push-6</Col>
      <Col span={6} pull={18}>col-6 col-pull-18</Col>
    </Row>
