Using Accessible Rich Internet Applications (ARIA) attributes
Whenever we are developing a web application, we will need to ensure that our applications are compatible with screen readers to support users with disabilities:
<div id="elem" aria-live="assertive" role="alert" aria-hidden="false"> An error occurred </div>
This information does not collide with any of the existing information on the screen, and it enables the screen readers to pick up and process this information. Of course, all of this is possible only if the HTML renderer supports ARIA, which is available in all the latest browsers.
