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.

<code>data-ui-placement</code> sets the side.

Icon-only buttons need a tooltip and an <code>aria-label</code> to explain them.

<span class="d-inline-block" tabindex="0" data-ui-toggle="tooltip" data-ui-title="Add a payment method first">
<button class="btn btn-primary" type="button" disabled>Upgrade</button>
</span>6Custom colors

<button type="button" class="btn btn-primary" data-ui-toggle="tooltip" data-ui-title="Styled with the theme primary colour" data-ui-custom-class="cb-tooltip">Custom tooltip</button>7Click trigger
<code>data-ui-trigger="click"</code> shows the tooltip only on click - useful on touch screens.
