Use to structure layouts, group related components, or control spacing between elements. ## Properties * accessibilityLabel string 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. * accessibilityRole AccessibilityRole 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. * accessibilityVisibility "visible" | "hidden" | "exclusive" 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. * alignContent AlignContentKeyword Aligns the Stack along the cross axis. * alignItems AlignItemsKeyword Aligns the Stack's children along the cross axis. * background BackgroundColorKeyword Adjust the background of the element. * blockSize "auto" | SizeUnits Adjust the block size. * border BorderShorthand 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`. * borderColor "" | ColorKeyword Set the color of the border. If set, it takes precedence over the `border` property's color. * borderRadius MaybeAllValuesShorthandProperty\ Set the radius of the border. [1-to-4-value syntax](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: `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`. * borderStyle "" | MaybeAllValuesShorthandProperty\ 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. * borderWidth "" | MaybeAllValuesShorthandProperty<"small" | "small-100" | "base" | "large" | "large-100" | "none"> 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. * columnGap MaybeResponsive<"" | SpacingKeyword> Adjust spacing between elements in the inline axis. This overrides the column value of `gap`. `columnGap` either accepts: * a single SpacingKeyword value (e.g. `large-100`) * OR a [responsive value](https://shopify.dev/docs/api/app-home/using-polaris-components#responsive-values) string with the supported SpacingKeyword as a query value. * direction MaybeResponsive<"inline" | "block"> Sets how the Stack's children are placed within the Stack. `direction` either accepts: * a single value either `inline` or `block` * OR a [responsive value](https://shopify.dev/docs/api/app-home/using-polaris-components#responsive-values) string with the supported SpacingKeyword as a query value. * display MaybeResponsive<"auto" | "none"> Sets the outer [display](https://developer.mozilla.org/en-US/docs/Web/CSS/display) type of the component. The outer type sets a component's participation in [flow layout](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_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. * gap MaybeResponsive\> Adjust spacing between elements. `gap` can either accept: * a single SpacingKeyword value applied to both axes (e.g. `large-100`) * OR a pair of values (eg `large-100 large-500`) can be used to set the inline and block axes respectively * OR a [responsive value](https://shopify.dev/docs/api/app-home/using-polaris-components#responsive-values) string with the supported SpacingKeyword as a query value. * inlineSize "auto" | SizeUnits Adjust the inline size. * justifyContent JustifyContentKeyword Aligns the Stack along the main axis. * maxBlockSize "none" | SizeUnits Adjust the maximum block size. * maxInlineSize "none" | SizeUnits Adjust the maximum inline size. * minBlockSize SizeUnits Adjust the minimum block size. * minInlineSize SizeUnits Adjust the minimum inline size. * overflow "visible" | "hidden" 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. * padding MaybeResponsive\> Adjust the padding of all edges. [1-to-4-value syntax](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 [responsive value](https://shopify.dev/docs/api/app-home/using-polaris-components#responsive-values) string with the supported PaddingKeyword as a query value. * paddingBlock MaybeResponsive<"" | MaybeTwoValuesShorthandProperty\> 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 [responsive value](https://shopify.dev/docs/api/app-home/using-polaris-components#responsive-values) string with the supported PaddingKeyword as a query value. * paddingBlockEnd MaybeResponsive<"" | PaddingKeyword> Adjust the block-end padding. This overrides the block-end value of `paddingBlock`. `paddingBlockEnd` also accepts a [responsive value](https://shopify.dev/docs/api/app-home/using-polaris-components#responsive-values) string with the supported PaddingKeyword as a query value. * paddingBlockStart MaybeResponsive<"" | PaddingKeyword> Adjust the block-start padding. This overrides the block-start value of `paddingBlock`. `paddingBlockStart` also accepts a [responsive value](https://shopify.dev/docs/api/app-home/using-polaris-components#responsive-values) string with the supported PaddingKeyword as a query value. * paddingInline MaybeResponsive<"" | MaybeTwoValuesShorthandProperty\> 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 [responsive value](https://shopify.dev/docs/api/app-home/using-polaris-components#responsive-values) string with the supported PaddingKeyword as a query value. * paddingInlineEnd MaybeResponsive<"" | PaddingKeyword> Adjust the inline-end padding. This overrides the inline-end value of `paddingInline`. `paddingInlineEnd` also accepts a [responsive value](https://shopify.dev/docs/api/app-home/using-polaris-components#responsive-values) string with the supported PaddingKeyword as a query value. * paddingInlineStart MaybeResponsive<"" | PaddingKeyword> Adjust the inline-start padding. This overrides the inline-start value of `paddingInline`. `paddingInlineStart` also accepts a [responsive value](https://shopify.dev/docs/api/app-home/using-polaris-components#responsive-values) string with the supported PaddingKeyword as a query value. * rowGap MaybeResponsive<"" | SpacingKeyword> Adjust spacing between elements in the block axis. This overrides the row value of `gap`. `rowGap` either accepts: * a single SpacingKeyword value (e.g. `large-100`) * OR a [responsive value](https://shopify.dev/docs/api/app-home/using-polaris-components#responsive-values) string with the supported SpacingKeyword as a query value. ### AccessibilityRole ```ts 'main' | 'header' | 'footer' | 'section' | 'aside' | 'navigation' | 'ordered-list' | 'list-item' | 'list-item-separator' | 'unordered-list' | 'separator' | 'status' | 'alert' | 'generic' | 'presentation' | 'none' ``` ### AlignContentKeyword Align content sets the distribution of space between and around content items along a flexbox's cross axis, or a grid or block-level element's block axis. ```ts 'normal' | BaselinePosition | ContentDistribution | OverflowPosition | ContentPosition ``` ### BaselinePosition ```ts 'baseline' | 'first baseline' | 'last baseline' ``` ### ContentDistribution ```ts 'space-between' | 'space-around' | 'space-evenly' | 'stretch' ``` ### OverflowPosition ```ts `unsafe ${ContentPosition}` | `safe ${ContentPosition}` ``` ### ContentPosition ```ts 'center' | 'start' | 'end' ``` ### AlignItemsKeyword Align items sets the align-self value on all direct children as a group. ```ts 'normal' | 'stretch' | BaselinePosition | OverflowPosition | ContentPosition ``` ### BackgroundColorKeyword ```ts 'transparent' | ColorKeyword ``` ### ColorKeyword ```ts 'subdued' | 'base' | 'strong' ``` ### SizeUnits ```ts `${number}px` | `${number}%` | `0` ``` ### BorderShorthand Represents a shorthand for defining a border. It can be a combination of size, optionally followed by color, optionally followed by style. ```ts BorderSizeKeyword | `${BorderSizeKeyword} ${ColorKeyword}` | `${BorderSizeKeyword} ${ColorKeyword} ${BorderStyleKeyword}` ``` ### BorderSizeKeyword ```ts SizeKeyword | 'none' ``` ### SizeKeyword ```ts 'small-500' | 'small-400' | 'small-300' | 'small-200' | 'small-100' | 'small' | 'base' | 'large' | 'large-100' | 'large-200' | 'large-300' | 'large-400' | 'large-500' ``` ### BorderStyleKeyword ```ts 'none' | 'solid' | 'dashed' | 'dotted' | 'auto' ``` ### MaybeAllValuesShorthandProperty ```ts T | `${T} ${T}` | `${T} ${T} ${T}` | `${T} ${T} ${T} ${T}` ``` ### BoxBorderRadii ```ts 'small' | 'small-200' | 'small-100' | 'base' | 'large' | 'large-100' | 'large-200' | 'none' ``` ### BoxBorderStyles ```ts 'auto' | 'none' | 'solid' | 'dashed' ``` ### MaybeResponsive ```ts T | `@container${string}` ``` ### SpacingKeyword ```ts SizeKeyword | 'none' ``` ### MaybeTwoValuesShorthandProperty ```ts T | `${T} ${T}` ``` ### JustifyContentKeyword Justify content defines how the browser distributes space between and around content items along the main-axis of a flex container, and the inline axis of a grid container. ```ts 'normal' | ContentDistribution | OverflowPosition | ContentPosition ``` ### PaddingKeyword ```ts SizeKeyword | 'none' ``` ### Examples * #### Code ##### Default ```html Paid Processing Filled Completed ``` ## Useful for * Placing items in rows or columns when sections don't work for your layout. * Controlling the spacing between elements. ## Considerations * Stack doesn't add any padding by default. If you want padding around your stacked elements, use `base` to apply the default padding. * When spacing becomes limited, Stack will always wrap children to a new line. ## Best practices * Use smaller gaps between small elements and larger gaps between big ones. * Maintain consistent spacing in stacks across all pages of your app.
