Accessible Rich Internet Applications (ARIA) is a set of attributes you can add to HTML elements to improve accessibility for people with disabilities. This guide provides an overview of ARIA and how to use it effectively.
What is ARIA?
ARIA is a specification developed by the World Wide Web Consortium (W3C) to help make web content and web applications more accessible to people with disabilities. It provides a way to communicate additional information about web elements to assistive technologies like screen readers.
Why Use ARIA?
- Improved Accessibility: ARIA can help make web content more accessible to people with disabilities, including those who are blind, deaf, or have cognitive disabilities.
- Enhanced User Experience: ARIA can improve the user experience for all users, not just those with disabilities.
- Compliance with Standards: Using ARIA can help you comply with accessibility standards like the Web Content Accessibility Guidelines (WCAG).
Common ARIA Attributes
Here are some common ARIA attributes and their purposes:
role: Defines the role of an element. For example,role="button"indicates that the element is a button.aria-label: Provides an accessible name for an element.aria-labelledby: Defines the ID of the element that provides the accessible name for another element.aria-describedby: Provides a description for an element.aria-hidden: Indicates whether an element is visible or not to assistive technologies.
Example
Here's an example of how to use ARIA attributes:
<button role="button" aria-label="Submit form">Submit</button>
This button has a role of "button" and an aria-label of "Submit form", which provides an accessible name for the button.
