Stack
Preview appears after the next Storybook update.
<Stack />When to use
Use it for
- Vertical rhythm inside cards, dialogs, forms and page sections.
- gap from the space scale: tight (1 to 2) inside a group, generous (6 to 8) between groups.
- render to output a semantic element: <section />, <ul />, <form />.
Not for
- Rows of items: use Inline.
- Two-dimensional layouts with columns: use Grid.
- Spacing one element only: give that element a margin class in your app, not a wrapper.
Do and don't
Every example is rendered with the real component, so it always matches what ships.
Nest stacks to show grouping
A tight stack per group inside a looser stack: the space itself says what belongs together.
One gap for everything
Equal spacing everywhere flattens hierarchy. Vary the gap to separate groups.
Accessibility
- A plain div by default with no role: it changes layout, not semantics.
- Use render to give the stack the right element (a list of items should be <ul />).
- Visual order equals DOM order, so reading and tab order stay consistent.
Content guidelines
- Not applicable: Stack holds no copy of its own.

Anatomy and tokens
Read from packages/react/src/components/Stack/Stack.module.css at build time. Every value is a token: open one to see its alias chain in both themes.
- Flex column
.stack
Motion and interaction
Stack does not animate: it only lays out other components.

Props
Parsed from the TypeScript types in packages/react/src/components/Stack/Stack.tsx, so this table cannot drift from the code. It also accepts every native <div> attribute.
| Prop | Type | Default | Description |
|---|---|---|---|
gap | '0' | '0-5' | '1' | '1-5' | '2' | '3' | '4' | '5' | '6' | '8' | '10' | '12' | '16' | none | Space between children, a key of the space scale. Default: the density token `layout.gap` (16 or 12px). |
align | 'start' | 'center' | 'end' | 'stretch' | 'baseline' | 'stretch' | Cross-axis alignment. Default `stretch`. |
justify | 'start' | 'center' | 'end' | 'between' | 'start' | Main-axis distribution. Default `start`. |
render | ReactElement | none | Render another element, for example `<section />` or `<ul />`. |
Comes with gapStyle, each accepting native <div> attributes.

For contributors: every state with the accessibility panel, in the component workbench (Storybook). The stories double as visual test fixtures; the guidance on this page is the user documentation (open Stack in Storybook).
