The rules are as follows:

- If the value is set to {minLength, maxLength}, the number of columns is adjusted adaptively based on the width of the **\** component, ensuring that the width respects the {minLength, maxLength} constraints during adaptation.

| size | {
width?: [Length](ts-types.md#length),
height?: [Length](ts-types.md#length)
} | Size of the component. |
| padding | [Padding](ts-types.md#padding) \| [Length](ts-types.md#length) | Padding of the component.
When the parameter is of the **Length** type, the four paddings take effect.
Default value: **0**
When **padding** is set to a percentage, the width of the parent container is used as the basic value.|
| margin | [Margin](ts-types.md#margin) \| [Length](ts-types.md#length) | Margin of the component.
When the parameter is of the **Length** type, the four margins take effect.
Default value: **0**
When **margin** is set to a percentage, the width of the parent container is used as the basic value.|

| layoutWeight | number \| string | Weight of the component during layout. When the container size is determined, the container space is allocated along the main axis among the component and sibling components based on the layout weight, and the component size setting is ignored.
**NOTE**
This attribute is valid only for the **\**, **\**, and **\** layouts.|
