ARIA can be a powerful tool for creating accessible web content. But it’s not a universal solution. When misused, it can actually generate accessibility barriers rather than removing them, creating confusion for assistive technologies and the users who rely on them. Understanding how and when to use it is key to creating truly accessible experiences.
Let's take a look.
What is ARIA?
Accessible Rich Internet Applications (ARIA) is a framework of roles and attributes designed to improve accessibility for web content and applications, particularly those built with JavaScript. It enhances HTML by allowing interactive elements and custom widgets to convey their purpose and behavior to assistive technologies when native HTML cannot.
If you can use a native HTML element or attribute with the semantics and behavior you require already built in, instead of re-purposing an element and adding an ARIA role, state, or property to make it accessible, then do so. ~ Using ARIA, W3C
There are valid reasons in which the use of ARIA is appropriate:
When HTML technically can do what you need, but the actual implementation falls short on accessibility support.
Example: Using
and for an accordion. These two elements should handle a basic accordion. They're semantic, simple, and even have built-in open / closed behavior.
But some screen readers still announce the state inconsistently, or they expose the toggle in ways that confuse users, especially when the pattern gets more complex than a single disclosure. Keyboard behavior also varies between browsers.
The lack of consistent accessibility support may require you to add ARIA roles (button, aria-expanded, aria-controls) and scripted behavior to make the experience reliable for everyone.
When design requirements won’t allow you to use the appropriate native element because the element can’t be styled or customized enough to meet the requirements.
Example: You want a toggle switch that matches your brand’s design with rounded edges, custom colors, and a smooth sliding animation. The native HTML can function as a toggle, but the browser largely controls its appearance.
In this case, developers often create a custom toggle using a
