noAutofocus

Diagnostic Category: lint/a11y/noAutofocus

Since: v1.0.0

Sources:

Enforce that autoFocus prop is not used on elements.

Autofocusing elements can cause usability issues for sighted and non-sighted users, alike. But the autofocus attribute should be added to the element the user is expected to interact with immediately upon opening a modal dialog or popover.
