# Accessibility

How to make sure your tooltips are usable by everyone, including keyboard and screen reader users.

import { Tooltip } from 'react-tooltip'

export const ButtonAnchor = ({ children, ...rest }) => (
<button
type="button"
style={{
display: 'flex',
justifyContent: 'center',
margin: 'auto',
alignItems: 'center',
width: '60px',
height: '60px',
borderRadius: '60px',
color: '#222',
background: 'rgba(255, 255, 255, 1)',
cursor: 'pointer',
boxShadow: '3px 4px 3px rgba(0, 0, 0, 0.5)',
border: '1px solid #333',
font: 'inherit',
padding: 0,
}}
{...rest}
>
{children}
</button>
)

Tooltips are covered by several [WCAG](https://www.w3.org/TR/WCAG22/) success criteria. The most relevant ones are:

- [**1.4.13 Content on Hover or Focus**](https://www.w3.org/TR/WCAG22/#content-on-hover-or-focus) — content shown on hover or focus must be **dismissible** (can be closed without moving the pointer or focus), **hoverable** (the pointer can move onto the content without it disappearing), and **persistent** (it stays visible until dismissed or no longer relevant).
- [**2.1.1 Keyboard**](https://www.w3.org/TR/WCAG22/#keyboard) — the tooltip must be reachable and triggerable with a keyboard alone, not only with a pointer.
- [**1.3.1 Info and Relationships**](https://www.w3.org/TR/WCAG22/#info-and-relationships) — the relationship between the anchor and its tooltip must be conveyed programmatically, so assistive technologies can announce it.

The rest of this page shows how each of these maps to ReactTooltip props and markup. The [full example](#putting-it-all-together) at the end combines them.

:::info

ReactTooltip already opens the tooltip when the anchor receives keyboard focus (not just on hover), so most of the work is making sure your anchor is focusable and correctly associated with the tooltip.

:::

## Hoverable content (1.4.13)

By default the tooltip disappears when the pointer leaves the anchor element — which means the pointer can't be moved onto the tooltip, and any buttons or links inside it are unreachable.

Use the `clickable` prop so the pointer can move onto the tooltip content without it closing. See the [Clickable tooltip example](./getting-started#clickable-tooltip) in the Getting Started section.

## Dismissible with `Esc` (1.4.13)

Users must be able to close the tooltip without moving the pointer or focus. Enable the `escape` global close event so pressing the <kbd>Esc</kbd> key dismisses it.

```jsx
<Tooltip
id="dismissible-tooltip"
globalCloseEvents={{ escape: true }}
/>
```

:::info

`globalCloseEvents` accepts other options too (`scroll`, `resize`, `clickOutsideAnchor`). See the [options page](./options#available-props) for the full list.

:::

## Keyboard-accessible anchor (2.1.1)

ReactTooltip opens the tooltip when the anchor receives focus, but only focusable elements can receive keyboard focus. Interactive elements such as `<a href="...">`, `<button>`, and form controls are focusable by default.

If your anchor is a non-interactive element (like a `<span>` or `<div>`), make it focusable by adding `tabIndex={0}`.

```jsx
// ✅ natively focusable
<button data-tooltip-id="my-tooltip">Help</button>

// ✅ made focusable
<span data-tooltip-id="my-tooltip" tabIndex={0}>Help</span>
```

:::caution

Prefer a natively interactive element when the anchor is meant to be interacted with. Adding `tabIndex={0}` to a `<span>` makes it focusable but does not give it a button's role or behavior.

:::

## Associating the anchor and tooltip (1.3.1)

So screen readers announce the tooltip content when the anchor is focused, add an `aria-describedby` attribute to the anchor referencing the tooltip's `id`.

Correct the aria-describedby guidance.

ReactTooltip adds its ID to the active anchor's aria-describedby while the tooltip is shown and removes it during cleanup. Do not instruct users to add this attribute manually. The static attribute can also reference an element that is not rendered before the tooltip opens.

near the tooltip anchor to remove the instruction to manually add
aria-describedby; state that ReactTooltip manages the active anchor’s
aria-describedby dynamically while the tooltip is visible and removes it during
cleanup.

```jsx
<button
data-tooltip-id="my-tooltip"
aria-describedby="my-tooltip"
>
Help
</button>
<Tooltip id="my-tooltip" content="Helpful description" />
```

:::info

ReactTooltip renders the tooltip element with `role="tooltip"`, so pairing it with `aria-describedby` gives assistive technologies the expected semantics.

:::

## Putting it all together

This example combines all of the above: a keyboard-focusable anchor, associated with the tooltip via `aria-describedby`, whose content is reachable (`clickable`) and can be dismissed with <kbd>Esc</kbd> (`globalCloseEvents`).

```jsx
import { Tooltip } from 'react-tooltip'

<button
data-tooltip-id="accessible-tooltip"
aria-describedby="accessible-tooltip"
>
◕‿‿◕
</button>
<Tooltip
id="accessible-tooltip"
clickable
globalCloseEvents={{ escape: true }}
>
<a
href="https://react-tooltip.com"
target="_blank"
rel="noreferrer"
style={{ color: '#8ab4f8' }}
>
Read the docs
</a>
</Tooltip>
```

<div style={{ display: 'flex', justifyContent: 'center', padding: '30px 0' }}>
<ButtonAnchor data-tooltip-id="accessible-tooltip" aria-describedby="accessible-tooltip">◕‿‿◕</ButtonAnchor>
<Tooltip
id="accessible-tooltip"
clickable
globalCloseEvents={{ escape: true }}
>
<a href="https://react-tooltip.com" target="_blank" rel="noreferrer" style={{ color: '#8ab4f8' }}>Read the docs</a>
</Tooltip>
</div>

:::tip

Try it with the keyboard: <kbd>Tab</kbd> to the anchor to open the tooltip, <kbd>Tab</kbd> again to move into the link, and <kbd>Esc</kbd> to dismiss it.

Make the keyboard flow focus-aware before documenting it.

When focus moves to the tooltip link, useTooltipEvents handles focusout because the link is outside the anchor. clickable then calls handleShow(false) after 100 ms unless hoveringTooltip is true, but keyboard focus does not set that ref. The tooltip may start closing before the link is activated. Keep it open while focus is inside the tooltip, or revise this instruction.

In `@docs/docs/accessibility.mdx` at line 155, Update the useTooltipEvents focus
handling so keyboard focus entering the tooltip link keeps hoveringTooltip true,
preventing clickable from calling handleShow(false) while focus remains inside
the tooltip; ensure the existing dismissal behavior resumes when focus leaves
the tooltip.

### Clickable tooltip/accessibility
### Clickable tooltip

By default the tooltip disappears when the pointer leaves the tooltip anchor element - which means you can't interact with elements inside the tooltip and that it won't meet the 'hoverable' requirement of [WCAG Success Criterion 1.4.13 Content on Hover or Focus](https://www.w3.org/TR/WCAG22/#content-on-hover-or-focus).
By default the tooltip disappears when the pointer leaves the tooltip anchor element, which means you can't interact with elements inside the tooltip.

To allow for proper usage of elements such as buttons and inputs - or to ensure the pointer can be moved over the tooltip content without it disappearing - use the `clickable` prop.

:::info

This is also required to meet the 'hoverable' requirement for accessible tooltips. See the [Accessibility page](./accessibility) for how to make your tooltips fully accessible.
