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 bg-body-tertiary">
  <button type="button" class="btn btn-sm btn-primary"><i class="bi bi-plus-lg" aria-hidden="true"></i> New</button>
  <button type="button" class="btn btn-sm btn-outline-secondary"><i class="bi bi-upload" aria-hidden="true"></i> Import</button>
  <div class="vr">
  </div>
  <button type="button" class="btn btn-sm btn-light" aria-label="Filter"><i class="bi bi-funnel-fill" aria-hidden="true"></i></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.

<form class="vstack gap-3" style="max-width:22rem">
  <div>
    <label class="form-label" for="hp-email-1236">Email</label>
    <input class="form-control" id="hp-email-1236" type="email" autocomplete="email">

  <div>
    <label class="form-label" for="hp-pass-1237">Password</label>
    <input class="form-control" id="hp-pass-1237" type="password" autocomplete="current-password">
