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 sections.
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.
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.
- 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 span={8} />`.
Our grid systems base on 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`.
| gutter | spacing between grids, could be a number or a object like `{ xs: 8, sm: 16, md: 24}`. or you can use array to make horizontal and vertical spacing work at the same time `[horizontal, vertical]` | number/object/array | 0 | | |
The breakpoints of responsive grid follow [BootStrap 4 media queries rules](https://getbootstrap.com/docs/4.0/layout/overview/#responsive-breakpoints)(not including `occasionally part`).
