Stack

Vertical layout container based on flexbox column

Overview

Stack is a vertical layout container. display: flex and flex-direction: column are applied by default.

Polymorphic — Render as any HTML element via the as prop
Interaction States — Supports state-based styling with _hover, _active, _focus, etc.
Sprinkles support — All design token props available

It is the vertical counterpart of Inline. The API is identical.
