A section of a page that consists of a composition that forms an independent part of a document, page, or site.
Setting an ARIA role and/or aria-* attribute that matches the default implicit ARIA semantics is unnecessary and is not recommended as these properties are already set by the browser.
<article>
<h1>My first article</h1>
<p>Lorem ipsum...</p>
</article>
You would use role=article
on non-semantic elements (not recommended, invalid)
<div role="article">
<h1>My first article</h1>
<p>Lorem ipsum...</p>
</div>
