Stacks

Stacks are flexbox shortcuts: vstack lines items up vertically, hstack horizontally, and the gap utilities space them evenly. Push an item to the far side with ms-auto and separate groups with a vertical rule.

1Horizontal toolbar

hstack with gap-2 lines up buttons; ms-auto pushes the last group to the far end.
