BlockStack

Use 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 alignment and spacing of the items in the stack. Use StackItem to group multiple elements inside a BlockStack together.

  • By default, BlockStack alignment is 'leading’.
