# jsx-a11y/no-aria-hidden-on-focusable
|
|
|
|
<!-- end auto-generated rule header -->
|
|
|
|
Enforce that `aria-hidden="true"` is not set on focusable elements.
|
|
|
|
`aria-hidden="true"` can be used to hide purely decorative content from screen reader users. An element with `aria-hidden="true"` that can also be reached by keyboard can lead to confusion or unexpected behavior for screen reader users. Avoid using `aria-hidden="true"` on focusable elements.

## Rule details
|
|
|
|
### Succeed
|
|
```jsx
|
|
<div aria-hidden="true" />
|
|
<img aria-hidden="true" />
|
|
<a aria-hidden="false" href="#" />
|
|
<button aria-hidden="true" tabIndex="-1" /> // `tabIndex=-1` removes the element from sequential focus navigation so we don't flag it.
|
|
<a href="/" />
|
|
<div aria-hidden="true"><a href="#"></a></div> // This is also bad but will not be handled by this rule.
|
|
```
|
|
|
|
### Fail
|
|
```jsx
|
|
<div aria-hidden="true" tabIndex="0" />
|
|
<input aria-hidden="true" />
|
|
<a href="/" aria-hidden="true" />
|
|
<button aria-hidden="true" />
|
|
<textarea aria-hidden="true" />
|
|
```
