## Style In addition to the styles in [Universal Styles](js-components-common-styles.md), the following styles are supported.

Name

Type

Default Value

Mandatory

Description

flex-direction

string

row

No

Main axis direction of the container. Available values are as follows:

  • column: Items are placed vertically from top to bottom.
  • row: Items are placed horizontally from left to right.

flex-wrap

string

nowrap

No

Whether items in the container are displayed in a single axis or multiple axes. Currently, dynamic modification is not supported. Available values are as follows:

  • nowrap: Items are displayed on a single axis.
  • wrap: Items are displayed on multiple axes.

justify-content

string

flex-start

No

How items are aligned along the main axis of the current row in the 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 of the current row in the 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 middle 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 of the container's cross axis and the first row is equal to the spacing between the end 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 rows 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.

display

string

flex

No

Type of the view box of the element. Currently, dynamic modification is not supported. Text alignment mode. Available values include:

  • flex: flexible layout
  • grid: grid layout
  • none: This item is not rendered.

grid-template-[columns|rows]

string

1 row, 1 column

No

Number of rows and columns in the current grid layout. If this attribute is not set, one row and one column are displayed by default. This attribute is valid only when display is set to grid.

For example, set grid-template-columns to:

(1) 50px 100px 60px: There are three columns. The first column is 50 px, the second column is 100 px, and the third column is 60 px.

(2) 1fr 1fr 2fr: There are three columns, and the width allowed by the parent component is divided into four equal shares. The first column occupies one share, the second column occupies one share, and the third column occupies two shares.

(3) 30% 20% 50%: There are three columns. The first column occupies 30% of the total width allowed by the parent component, the second column occupies 20%, and the third column occupies 50%.

(4) repeat (2,100px): There are two columns. The first column is 100 px, and the second column is 100 px.

(5) auto 1fr 1fr: There are three columns. The first column is adaptive to the width required by its child components. The remaining space is divided into two equal shares, one share occupied by each of the two columns.

grid-[columns|rows]-gap

<length>

0

No

Size of the gap between two consecutive rows or columns in a grid layout. You can also use grid-gap to set the same size of the gap between rows and columns. This attribute is valid only when display is set to grid.
