ARIA stands for Accessible Rich Internet Applications. ARIA roles are used in HTML to improve accessibility for people using screen readers and other assistive technologies.
What are ARIA Roles
ARIA roles are special attributes added to HTML elements to describe their purpose more clearly. They help assistive tools understand how a part of the webpage should behave.
Why ARIA Roles are Important
Some HTML elements or custom components may not be fully understood by screen readers. ARIA roles help fill this gap by giving extra meaning to those elements.
Example of ARIA Role
<div role=”navigation”> <a href=”index.html”>Home</a> <a href=”about.html”>About</a> </div>
Common ARIA Roles
navigation is used for menus and navigation bars.
button is used for clickable actions.
main is used for the main content of the page.
banner is used for the header section.
contentinfo is used for footer information.
Example of Button Role
<div role=”button” tabindex=”0″>Click Me</div>
What is tabindex
The tabindex attribute allows non-button elements to be focusable using the keyboard.
Best Practices for ARIA Roles
Use semantic HTML first before adding ARIA roles.
Do not overuse ARIA roles if HTML already provides meaning.
Always test with screen readers when possible.
Summary
ARIA roles improve web accessibility by helping assistive technologies understand webpage elements better. They should be used carefully along with proper HTML structure.
