Static HTML elements do not have semantic meaning. This is clear in the case of <div>
and <span>
. It is less so clear in the case of elements that seem semantic, but that do not have a semantic mapping in the accessibility layer. For example <a>
, <big>
, <blockquote>
, <footer>
, <picture>
, <strike>
and <time>
-- to name a few -- have no semantic layer mapping. They are as void of meaning as <div>
.
The WAI-ARIA role
attribute confers a semantic mapping to an element. The semantic value can then be expressed to a user via assistive technology.
In order to add interactivity such as a mouse or key event listener to a static element, that element must be given a role value as well.
<div onClick={() => {}} />
<button onClick={() => {}} className="foo" />
<div className="foo" onClick={() => {}} role="button" />
<input type="text" onClick={() => {}} />
