Sets and gets the Accessible Rich Internet Application (ARIA) attributes of the element.
ARIA attributes are a set of properties that define ways to make web content and applications more accessible to people with disabilities. The properties provide additional information about the structure, behavior, and state of elements to assistive technologies such as screen readers, braille displays, and voice control software. Set the accessibility properties to design your elements to be more inclusive and usable to users with visual, auditory, motor, and or cognitive disabilities. The accessibility object only affects how assistive technologies read and present site content to users. It doesn't affect the appearance, functionality, or SEO of your site.
Note: Incorrect use of ARIA can worsen accessibility for assistive technology users. Use carefully and test with assistive technologies.
