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.

<div class="hstack gap-2 p-2 border rounded-md bg-surface-3">

  <button type="button" class="btn btn-sm btn-outline-secondary"><i class="bi bi-upload" aria-hidden="true"></i> Import</button>

  <button type="button" class="btn btn-sm btn-light ms-auto" aria-label="Settings"><i class="bi bi-gear-fill" aria-hidden="true"></i></button>
</div>

2Vertical sign-in form

vstack with gap-3 spaces the fields of a compact form without margin utilities.

    <input class="form-control" id="hp-email-1236" type="email" autocomplete="email">
