Demystifying aria-label: A Guide with Practical Examples

What is aria-label?

In the world of web accessibility, the aria-label attribute plays a crucial role. It’s a powerful tool that allows you to provide a text alternative for elements that don’t have a visible text label. This is especially important for assistive technologies like screen readers, which rely on text to convey information to users with disabilities.

Essentially, aria-label is an attribute that you can add to HTML elements. It provides a textual label that is read out by assistive technologies but is not visually displayed on the webpage. This helps ensure that all users, regardless of their abilities, can understand the purpose and function of every element on your site.

Why Use aria-label?

There are several scenarios where using aria-label is beneficial:

Icons and Images: When you use icons or images as buttons or links without accompanying text, aria-label provides the necessary textual context.
Complex Controls: For intricate user interface elements that might not have a clear text label, aria-label clarifies the element’s function.
Elements with Hidden Text: In cases where text labels are visually hidden for design purposes, aria-label ensures accessibility.

Practical Examples of aria-label

Let’s dive into some real-world examples to understand how aria-label can be used effectively:

Example 1: Icon Button

Imagine a social media website with a heart icon to represent the “like” action. Without any context, screen reader users won’t know what the heart icon represents. Here’s how aria-label can help:

<button aria-label="Like this post"><img src="heart.png" alt=""/></button>

In this code snippet, the aria-label="Like this post" attribute provides a text alternative for the heart icon, informing assistive technologies that the button is intended for liking the post.

Example 2: Search Button

Consider a website with a search bar, the button to submit a search has a magnifying glass icon. Without aria-label, it’s not apparent that the icon means ‘search’.

<button aria-label="Search"><img src="search.png" alt=""/></button>

Here, the aria-label="Search" makes it clear for all users, including those with assistive technologies, that the button triggers a search action.

Example 3: Close Button

Many modal windows have an ‘X’ icon to close the modal, using the aria-label ensures all users understand what the button does

<button aria-label="Close Modal"><img src="close.png" alt=""/></button>

In this case, the aria-label="Close Modal" provides assistive technologies with the purpose of this button.

Best Practices for aria-label

While aria-label is incredibly useful, it’s essential to use it correctly.

Be Concise: Keep the aria-label text short and descriptive.
Avoid Redundancy: Do not repeat information that is already clear from the context.
Test: Always test your aria-label implementation with screen readers to ensure it conveys the correct information.
Use alternative techniques: If the text can be made visible, it is recommended to do so and avoid relying on aria-label when visible text can be used instead.

Conclusion

aria-label is a powerful tool for creating accessible and user-friendly websites. By providing meaningful text alternatives for elements that lack visible labels, you can significantly improve the experience of users with disabilities. Understanding and implementing aria-label effectively is essential for anyone looking to build inclusive and equitable web experiences. Remember to use it thoughtfully, testing with assistive technologies to ensure the best result.
