Tooltips
Tooltips are tiny labels that appear on hover or focus. They name icon buttons, explain terms and show full text that was cut off. Below you will find placements, triggers, disabled wrappers, custom colours and many real spots such as toolbars, avatar stacks, tables and sidebars.
1Basic tooltip
Hover or focus the button to see its tooltip.
<button type="button" class="btn btn-secondary" data-bs-toggle="tooltip" data-bs-title="Saves a copy to your account">Hover me</button>2Four directions
<code>data-bs-placement</code> sets the side.
<div class="d-flex flex-wrap gap-2">

<button type="button" class="btn btn-outline-secondary" data-bs-toggle="tooltip" data-bs-title="Tooltip on left" data-bs-placement="left">Tooltip on left</button>
</div>3Links in text
Tooltips on inline links give extra context without clutter.

Icon-only buttons need a tooltip and an <code>aria-label</code> to explain them.
<div class="btn-toolbar gap-1" role="toolbar" aria-label="Item actions">
<button type="button" class="btn btn-light border" data-bs-toggle="tooltip" data-bs-title="Edit" aria-label="Edit"><i class="bi bi-pencil" aria-hidden="true"></i></button>

<button type="button" class="btn btn-light border" data-bs-toggle="tooltip" data-bs-title="Delete" aria-label="Delete"><i class="bi bi-trash" aria-hidden="true"></i></button>
</div>5Disabled wrapper
Wrap a disabled button in a focusable span so the tooltip still shows.
<span class="d-inline-block" tabindex="0" data-bs-toggle="tooltip" data-bs-title="Add a payment method first">
<button class="btn btn-primary" type="button" disabled>Upgrade</button>
</span>6Custom colors
<code>data-bs-custom-class</code> plus a few CSS variables give the tooltip your brand colour.
<button type="button" class="btn btn-primary" data-bs-toggle="tooltip" data-bs-title="Styled with the theme primary colour" data-bs-custom-class="cb-tooltip">Custom tooltip</button>7Click trigger
<code>data-bs-trigger="click"</code> shows the tooltip only on click - useful on touch screens.
