Use to lay out a horizontal row of components or to achieve no-fuss vertical centering. A stack is made of flexible items that wrap each of the stack’s children. Options provide control of the wrapping, spacing, and relative size of the items in the stack.


Use to quickly lay out a horizontal row of components and maintain their relative sizes. On small screens, children rows wrap down to additional rows as needed.

"leading" | "trailing" | "center" | "fill" | "baseline"
Adjust vertical alignment of elements
Elements to display inside stack
"equalSpacing" | "leading" | "trailing" | "center" | "fill" | "fillEvenly"
Adjust horizontal alignment of elements
"extraTight" | "tight" | "baseTight" | "loose" | "extraLoose" | "none"
Adjust spacing between elements
Stack the elements vertically
Wrap stack elements to additional rows as needed on small screens (Defaults to true)


The stack component is for alignment only and doesn’t provide any structural information for assistive technologies. To convey relationships between specific items, consider using the list component.

Best practices

Stacks should:

  • Be used for small-scale layout tasks when you want a row of components that should wrap on small screen widths
  • Be used to vertically center two elements
  • Not be used for complex or unique arrangements of components
  • Not be used for large-scale page layout

Stack item

The stack component will treat multiple elements wrapped in a stack item component as one item. By default, each individual element is treated as one stack item. Use the fill prop on a single stack item component to make it fill the rest of the available horizontal space. See the “Stack where a single item fills the remaining space” example.

Stack item properties

Prop Type Description Default
fill boolean Fill the available horizontal space in the stack with the item false
children any Elements to display inside stack item
