Tooltips have some basic attributes to help with accessibility.

It's recommended that tooltips are applied only to natively focusable elements like <button>. Most screenreader software will not announce the tooltip on an element like <div>.


The default trigger for tooltips is "mouseenter focus". This means both a hover and focus via keyboard navigation will trigger a tooltip.

ARIA attributes

By default, the reference element receives an aria-describedby attribute (configurable) once the tooltip is fully shown.

<button aria-describedby="tippy-1">Text</button>
<div id="tippy-1" role="tooltip" class="tippy-popper">
  <!-- inner elements -->

This allows screenreader software to announce the tooltip content describing the reference element. No work is required by you to achieve this functionality.

Popovers and interactivity

By default, interactive tippys will be auto-focused once they are fully shown to allow the user to interact with elements inside it. However, some additional work will be needed in certain cases.

It's recommended that an interactive tippy with a focus trigger is appended directly after the reference element in the DOM tree using the appendTo option and have autoFocus disabled. If triggered by a click, the default options suffice.

For UI elements like dropdowns, you should apply these attributes to the reference:

  • aria-haspopup="true"
  • aria-expanded="false"
<!-- The element should have its own wrapper. -->
  <button aria-haspopup="true" aria-expanded="false">Text</button>

We will need to dynamically change the aria-expanded attribute based on the state of the tooltip:

tippy('button', {
  autoFocus: false,
  appendTo: ref => ref.parentNode,
  onMount({ reference }) {
    reference.setAttribute('aria-expanded', 'true')
  onHide({ reference }) {
    reference.setAttribute('aria-expanded', 'false')

Elements within the tippy can be tabbed to since they are directly after the reference element. The tooltip automatically hides once no elements inside it are in focus.

If for some reason you don't want the tooltip to hide once blurred, you can define the following option:

tippy('button', {
  shouldPopperHideOnBlur(focusOutEvent) {
    // You can read the `focusout` event object
    // to determine which boolean should be returned.
    return false
