BACKGROUND:
Every user interface control must have a role along with any applicable states and properties so that screen reader users know how to interact with the control. Native HTML elements - such as <button>, <a>, <input>, <select> - already have a role, and their necessary states and properties - such as the checked/unchecked state of a checkbox - are automatically conveyed so nothing more needs to be done. If you create a custom version of a native HTML element or a custom control or widget that does not have a native HTML equivalent, you must add the relevant role(s) and any applicable states and properties using ARIA as well as expected keyboard interactions.
