Box

A label that describes the purpose or contents of the element. When set, it will be announced to users using assistive technologies and will provide them with more context.

Only use this when the element's content is not enough context for users using assistive technologies.

Sets the semantic meaning of the component’s content. When set, the role will be used by assistive technologies to help users navigate the page.

Changes the visibility of the element.

• visible: the element is visible to all users.
• hidden: the element is removed from the accessibility tree but remains visible.
• exclusive: the element is visually hidden but remains in the accessibility tree.

Adjust the background of the element.

Adjust the block size.

Set the border via the shorthand property.

This can be a size, optionally followed by a color, optionally followed by a style.

If the color is not specified, it will be base.

If the style is not specified, it will be auto.

Values can be overridden by borderWidth, borderStyle, and borderColor.

Set the color of the border.

If set, it takes precedence over the border property's color.

Set the radius of the border.

1-to-4-value syntax is supported. Note that, contrary to the CSS, it uses flow-relative values and the order is:

• 4 values: start-start start-end end-end end-start
• 3 values: start-start (start-end & end-start) start-end
• 2 values: (start-start & end-end) (start-end & end-start)

For example:

• small-100 means start-start, start-end, end-end and end-start border radii are small-100.
• small-100 none means start-start and end-end border radii are small-100, start-end and end-start border radii are none.
• small-100 none large-100 means start-start border radius is small-100, start-end border radius is none, end-end border radius is large-100 and end-start border radius is none.
• small-100 none large-100 small-100 means start-start border radius is small-100, start-end border radius is none, end-end border radius is large-100 and end-start border radius is small-100.

Set the style of the border.

If set, it takes precedence over the border property's style.

Like CSS, up to 4 values can be specified.

If one value is specified, it applies to all sides.

If two values are specified, they apply to the block sides and inline sides respectively.

If three values are specified, they apply to the block-start, both inline sides, and block-end respectively.

If four values are specified, they apply to the block-start, block-end, inline-start, and inline-end sides respectively.

Set the width of the border.

If set, it takes precedence over the border property's width.

Like CSS, up to 4 values can be specified.

If one value is specified, it applies to all sides.

If two values are specified, they apply to the block sides and inline sides respectively.

If three values are specified, they apply to the block-start, both inline sides, and block-end respectively.

If four values are specified, they apply to the block-start, block-end, inline-start, and inline-end sides respectively.

Sets the outer display type of the component. The outer type sets a component's participation in flow layout.

• auto the component's initial value. The actual value depends on the component and context.
• none hides the component from display and removes it from the accessibility tree, making it invisible to screen readers.

Adjust the inline size.

Adjust the maximum block size.

Adjust the maximum inline size.

Adjust the minimum block size.

Adjust the minimum inline size.

Sets the overflow behavior of the element.

• hidden: clips the content when it is larger than the element’s container. The element will not be scrollable and the users will not be able to access the clipped content by dragging or using a scroll wheel on a mouse.
• visible: the content that extends beyond the element’s container is visible.

Adjust the padding of all edges.

1-to-4-value syntax (@see https://developer.mozilla.org/en-US/docs/Web/CSS/Shorthand_properties#edges_of_a_box) is supported. Note that, contrary to the CSS, it uses flow-relative values and the order is:

• 4 values: block-start inline-end block-end inline-start
• 3 values: block-start inline block-end
• 2 values: block inline

For example:

• large means block-start, inline-end, block-end and inline-start paddings are large.
• large none means block-start and block-end paddings are large, inline-start and inline-end paddings are none.
• large none large means block-start padding is large, inline-end padding is none, block-end padding is large and inline-start padding is none.
• large none large small means block-start padding is large, inline-end padding is none, block-end padding is large and inline-start padding is small.

A padding value of auto will use the default padding for the closest container that has had its usual padding removed.

padding also accepts a container query string with the supported PaddingKeyword as a query value e.g. (@container (inline-size > 500px) large-300, small-300)

This also accepts up to 4 values (e.g. @container (inline-size > 500px) large-300 small-300 large-100 small-100, small-200)

Adjust the block-padding.

• large none means block-start padding is large, block-end padding is none.

This overrides the block value of padding.

paddingBlock also accepts a container query string with the supported PaddingKeyword as a query value e.g. (@container (inline-size > 500px) large-300, small-300)

This also accepts up to 2 values (e.g. @container (inline-size > 500px) large-300 small-300, small-200)

Adjust the block-end padding.

This overrides the block-end value of paddingBlock.

paddingBlockEnd also accepts a container query string with the supported PaddingKeyword as a query value e.g. (@container (inline-size > 500px) large-300, small-300)

This only accepts up to 1 value per predicate (e.g. @container (inline-size > 500px) large-300, small-200)

Adjust the block-start padding.

This overrides the block-start value of paddingBlock.

paddingBlockStart also accepts a container query string with the supported PaddingKeyword as a query value e.g. (@container (inline-size > 500px) large-300, small-300)

This only accepts 1 value per predicate (e.g. @container (inline-size > 500px) large-300, small-200)

Adjust the inline padding.

• large none means inline-start padding is large, inline-end padding is none.

This overrides the inline value of padding.

paddingInline also accepts a container query string with the supported PaddingKeyword as a query value e.g. (@container (inline-size > 500px) large-300, small-300)

This also accepts up to 2 values (e.g. @container (inline-size > 500px) large-300 small-300, small-200)

Adjust the inline-end padding.

This overrides the inline-end value of paddingInline.

paddingInlineEnd also accepts a container query string with the supported PaddingKeyword as a query value e.g. (@container (inline-size > 500px) large-300, small-300) This only accepts 1 value per predicate (e.g. @container (inline-size > 500px) large-300, small-200)

Adjust the inline-start padding.

This overrides the inline-start value of paddingInline.

paddingInlineStart also accepts a container query string with the supported PaddingKeyword as a query value e.g. (@container (inline-size > 500px) large-300, small-300) This only accepts 1 value per predicate (e.g. @container (inline-size > 500px) large-300, small-200)
