ARIA Roles: Accessible Web Development — Part 2

ARIA Roles- Accessible Web Development

In the first section, we explored the various categories of ARIA roles and their importance in web accessibility. Now, it’s time to put that knowledge into practice. In this section, we will guide you through the process of incorporating ARIA roles in your HTML markup to create more accessible and user-friendly websites. Get ready to level up your web development skills and make a real impact on your users’ experience!

Section 2: Implementing ARIA Roles in HTML

Now that we have explored the various ARIA roles, let’s discuss how to incorporate them into your HTML markup.

2.1 Adding ARIA Roles to HTML Elements

To add an ARIA role to an HTML element, use the ‘role’ attribute followed by the specific role you want to assign. Here’s an example:

<nav role="navigation">
  <!-- Your navigation menu code -->

In this example, we have assigned the navigation landmark role to the <nav> element, which helps screen readers and other assistive technologies identify the purpose of this section.

2.2 ARIA Role Best Practices

While implementing ARIA roles, it’s essential to follow best practices to ensure optimal accessibility. Here are some key points to consider:

  • Use appropriate roles: Choose the most accurate and specific role for each element, considering the element’s purpose and behavior.
  • Avoid role duplication: If an HTML5 element has an implicit role, avoid adding a redundant ARIA role. For example, the <nav> element already has an implicit ‘navigation’ role, so adding role="navigation" is unnecessary.
  • Test with assistive technologies: Regularly test your website with various assistive technologies like screen readers to ensure that your ARIA roles are correctly implemented and accessible to users.

Section 3: Enhancing ARIA with States and Properties

In addition to roles, ARIA provides states and properties to further define the behavior and characteristics of web components. While roles describe an element’s purpose, states and properties offer additional information about an element’s current status or configuration.

3.1 ARIA States

ARIA states define the current condition of an element. Some examples of ARIA states include:

  • aria-checked: Indicates whether a checkbox or radio button is checked
  • aria-disabled: Indicates whether an element is disabled
  • aria-expanded: Indicates whether a collapsible section is expanded or collapsed
3.2 ARIA Properties

ARIA properties provide extra information about an element that may not be evident from its role or states. Examples of ARIA properties include:

  • aria-label: Provides a label for an element when a visible label isn’t present
  • aria-describedby: Identifies an element or elements that describe another element
  • aria-controls: Indicates the element or elements controlled by the current element

By combining ARIA roles, states, and properties, you can create a robust and accessible user experience for your web applications.


ARIA roles are a powerful tool in ensuring web accessibility for all users. By understanding the different role categories and implementing them effectively in your HTML markup, you can create web applications that are both accessible and enjoyable to use. Remember to follow best practices and continually test your website with assistive technologies to ensure optimal accessibility. Happy coding!
