Sets and gets the Accessible Rich Internet Application (ARIA) attributes and other accessibility properties for 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 for visitors with visual, auditory, motor, and or cognitive disabilities. The accessibility object primarily affects how assistive technologies read and present site content. ARIA attributes themselves do not impact SEO, but other accessibility properties, such as lang, can influence content indexing and discoverability.
Note: Incorrect use of ARIA attributes can worsen accessibility for assistive technology users. Use carefully and test with assistive technologies.
