Overview

WAI-ARIA (Web Accessibility Initiative - Accessible Rich Internet Applications) is a set of attributes that can make interactive web content more accessible to people with disabilities. It can explicitly create semantic associations between different HTML elements, and can provide information to assistive technologies without exposing that same information to most users. It can help you do things like:

• Inform screen readers when the state of content changes
• Tell you when new content dynamically renders on the page
• Alert you that a link will open in a popup
