Why the audit is important
Invalid ARIA attribute values may be preventing the screen reader from properly understanding the current state of a widget. This could make the page unusable to users who rely on screen readers.
See Introduction to ARIA for more information.

1 element fails
this test. The number varies depending on how many elements are failing.
Click this label to expand the list. You can find each element in your
DOM by running the
from the Chrome DevTools Console.
To find each listed element's invalid attribute values:
aria-*attributes of the element.
aria-*attribute of the element, go the page for that attribute.
Make the value of the element's attribute match one of the supported values listed in Value.
