Web Accessibility Guidelines: Understanding ARIA Landmarks for Enhanced Navigation

Web accessibility is crucial for creating an inclusive online environment. One of the key components of the Web Content Accessibility Guidelines (WCAG) 2.2 is the use of Accessible Rich Internet Applications (ARIA) landmarks. These landmarks help improve navigation for users of assistive technologies by providing them with a way to quickly identify and jump to different sections of a webpage.

What are ARIA Landmarks?

ARIA landmarks are specific HTML attributes that define regions of a web page, enabling screen readers to convey the structure of a page effectively. By using ARIA roles, developers can inform users where they are on a page, making navigation easier and enhancing their experience.

Common ARIA Landmarks

Some of the most commonly used ARIA landmark roles include:

• banner: Represents the introductory content or navigational links at the top of the page.
• navigation: Denotes a section of navigational links.
• main: Identifies the main content area of the document.
• complementary: Represents content that is related to the main content but is separate from it.
• contentinfo: Typically contains information about the author, copyright, or other related data.

Using these ARIA roles correctly enhances accessibility and improves the overall user experience.

Implementing ARIA Landmarks in HTML

Below is an example of how to implement ARIA landmarks in an HTML document:

<header role="banner">
    <h1>Website Title</h1>
    <nav role="navigation">
        <ul>
            <li><a href="#home">Home</a></li>
            <li><a href="#about">About</a></li>
            <li><a href="#services">Services</a></li>
            <li><a href="#contact">Contact</a></li>
        </ul>
    </nav>
</header>

<main role="main">
    <section id="home">
        <h2>Welcome to Our Website</h2>
        <p>This is the main content area.</p>
    </section>

    <section id="about">
        <h2>About Us</h2>
        <p>Information about our company.</p>
    </section>

    <section id="services">
        <h2>Our Services</h2>
        <p>Details about services offered.</p>
    </section>
</main>

<aside role="complementary">
    <h2>Related Information</h2>
    <p>Additional links or information goes here.</p>
</aside>

<footer role="contentinfo">
    <p>Copyright © 2023 Company Name</p>
</footer>

In this example, different ARIA roles are assigned to the header, main content, complementary content, and footer sections. This structured approach allows assistive technologies to better communicate the layout of the page to users.

How to Remediate Links with WP ADA Compliance Check

Manually tracking down hidden structural code fragments across a massive content catalog or a complex multi-author site can take dozens of tedious hours. Deploying a comprehensive tool like the WP ADA Compliance Check Plugin completely automates the process of auditing, reporting and sometimes correcting critical web accessibility errors.

Automated Remediation

The plugin evaluates your database content against 83 thorough accessibility checks and automatically corrects 42 distinct error types. During deep site scans, it uncovers hidden errors and highlights the exact location of the issue, saving developers from manually hunting through the raw HTML editor.

Enforcing Pre-Publishing Safeguards

To ensure that new content modifications don’t break compliance, the plugin features robust Pre-Publishing Controls. If an editor tries to publish a page containing web accessibility errors, the plugin alerts the user or restricts publication. This content safeguard forces correction at the workflow source before the page goes live.

Getting Started

If you are not sure where to begin with web accessibility, start by using the WP ADA Compliance Check Free Web Accessibility Scanner to run a scan of your website. For a more integrated solution, WordPress website owners should also try the free WP ADA Compliance Check Basic plugin to automatically audit posts and pages for common compliance issues right from their dashboard.
