Check whether you can use a different HTML element which matches the element’s functionality, e.g. use an <a> element if the element acts as a link. In case this is not possible add a role attribute to the element, using one of the WAI-Aria roles according to the specification.
The engine scans all elements having one of the following events: keydown, keyup, keypress, click, dblclick, mousedown and mouseup for an appropriate role.
Users who use assistive tools, such as screen readers, rely on exposure of the role attribute to understand the context such as a button, link. Exposing the role enables users to understand the widget and how to interact with it.
