Optimizing Your Website for Screen Reader Users: How to Make a List Accessible

Creating an accessible website is crucial for reaching a broader audience, especially those with visual impairments. Screen readers are tools that help these users navigate the web by reading out the content on a web page. This article will guide you through the steps to ensure that your website's lists are fully accessible to screen reader users, maximizing the user experience.

Understanding Screen Readers and Web Accessibility

Screen readers are software applications that convert on-screen text to synthesized speech, refreshable Braille display, or other outputs. They enable visually impaired users to browse and interact with websites effectively. Proper web accessibility is about making your content and navigation tools understandable and usable by everyone, including those using assistive technologies.

Common Screen Readers and Their Navigation Techniques

Two popular screen readers are JAWS (Job Access With Speech) and NVDA (NonVisual Desktop Access). Users of these screen readers can navigate through website content using various keyboard shortcuts and commands.

Using JAWS to Navigate Lists

In JAWS, the L key is used to navigate to a list. To navigate to a list item, users can press the IEye key. These shortcuts allow screen reader users to quickly and efficiently locate and interact with list elements on a page.

Using NVDA to Navigate Lists

NVDA also employs similar shortcuts for list navigation. The L key is used to navigate to a list, and the I key is used to navigate to a list item. This key combination simplifies the process of finding specific items within a list.

Navigating Lists via the DOM

For users of screen readers, navigating through the Document Object Model (DOM) is a powerful technique. By using the up/down arrow keys, users can traverse an HTML document, including list items. This method provides a comprehensive way to explore and interact with the content on a web page.

Optimizing Web Content for Screen Readers

Creating accessible lists goes beyond just using keyboard shortcuts. Here are some best practices to ensure your lists are fully accessible to screen reader users:

Proper Semantic HTML

Using semantic HTML is critical for improving accessibility. For example:

ul  liItem 1/li  liItem 2/li/ul

The ul (unordered list) and li (list item) tags are recognized by screen readers, making the list structure clear and easy to navigate.

aria-labels and aria-describedby

If you have complex lists or need to provide additional context, use ARIA (Accessible Rich Internet Applications) attributes like aria-label and aria-describedby. These attributes can provide more detailed information about the list to screen reader users.

ARIA Roles for Custom Lists

For custom lists that don't conform to semantic HTML, the role"list" and role"listitem" attributes can be used to define the list structure in a way that screen readers can understand. For example:

div role"list"  div role"listitem"Custom List Item 1/div  div role"listitem"Custom List Item 2/div/div

Ensure Consistent and Predictable Behavior Across Devices

It's essential to test your website's accessibility across different devices and screen readers. Many developers use iOS devices and VoiceOver, a built-in screen reader, to ensure consistent performance. VoiceOver users on iOS devices can set their rotor settings to navigate through lists more efficiently.

Testing on iOS Devices with VoiceOver

On iOS, users can set their rotor to 'list' mode to quickly jump to list items and navigate through them. Rotor settings can be configured via the assistiveTouch or VoiceOver settings in the iPhone or iPad settings menu.

Conclusion

Ensuring that your website is accessible to screen reader users is not only ethical but also necessary to comply with accessibility laws and standards. By implementing the best practices mentioned above, you can create a more inclusive online environment, enhancing the user experience for all visitors.
