Attributes

In addition to the universal attributes, the following attributes are supported.

Name	Type	Default Value	Mandatory	Description
columns	string \|number	auto	No	Total number of columns in the grid. If a value of the string type is set, it can only be auto. In this case, the total number of columns is determined based on the current sizetype, which can be one of the following values: - xs: 2 columns - sm: 4 columns - md: 8 columns - lg: 12 columns
sizetype	string	auto	No	Size-responsive type of the grid. Available values are xs, sm, md, and lg. If the default value auto is used, the framework automatically selects one of the four types based on the current container size.
gutter	<length>	24px	No	Gutter width.
gridtemplate⁶⁺	string	default	No	Layout template of the grid, which defines the columns, gutters, and margins for different size-responsive types. This attribute is available when columns and sizetype are set to auto. For details about the values, see gridtemplate.

Table 1 gridtemplate⁶⁺

	Template Value	Size-responsive Type	Columns	Margins (px)	Gutters (px)
Default grid	default	xs	2	12	12
		sm	4	24	24
		md	8	32	24
		lg	12	48	24
Grid layout	grid	sm (0 < Device horizontal resolution < 600px)	4	24	12
		md	8	32	12
		lg	12	48	12

NOTE

The px unit is applicable when autoDesignWidth is set to true in the “js” tag.⁶⁺

Styles

In addition to the universal styles, the following styles are supported.

Name	Type	Default Value	Mandatory	Description
justify-content	string	flex-start	No	How items are aligned along the main axis of the flex container. Available values are as follows: - flex-start: Items are packed towards the start row. - flex-end: Items are packed towards the end row. - center: Items are centered along the row. - space-between: Items are positioned with space between the rows. - space-around: Items are positioned with space before, between, and after the rows.
align-items	string	stretch	No	How items are aligned along the cross axis in a flex container. Available values are as follows: - stretch: Items are stretched to the same height or width as the container in the cross axis direction. - flex-start: Items are aligned to the start of the cross axis. - flex-end: Items are aligned to the end of the cross axis. - center: Items are aligned in the center of the cross axis.
align-content	string	flex-start	No	Multi-row alignment mode when there is extra space in the cross axis. Available values are as follows: - flex-start: All rows are packed towards the start of the cross axis. The start edge of the cross axis of the first row is aligned with the start edge of the cross axis of the container. All subsequent rows are aligned with the previous row. - flex-end: All rows are packed towards the end of the cross axis. The end of the cross axis of the last row is aligned with the end of the cross axis of the container. All subsequent rows are aligned with the previous row. - center: All rows are packed towards the center of the container. Rows are close to each other and aligned with the center of the container. The spacing between the start edge of the container’s cross axis and the first row is equal to the spacing between the end edge of the container’s cross axis and the last row. - space-between: All rows are evenly distributed in the container. The spacing between two adjacent rows is the same. The start and end edges of the container’s cross axis are aligned with the edges of the first and last rows, respectively. - space-around: All rows are evenly distributed in the container, and the spacing between two adjacent lines is the same. The spacing between the start edge of the container’s cross axis and the first row and that between the end edge and the last row are half of the spacing between two adjacent rows.

Events
