Importance of 2.4.6: Headings and Labels Success Criterion

Clear and descriptive headings and labels are crucial for accessibility. They provide users with a clear understanding of the structure and content of a webpage, making it easier to navigate and find information. This is particularly important for users with cognitive disabilities and those using screen readers.

How to Implement 2.4.6: Headings and Labels

                        <h1>Main Title</h1>
                        <h2>Section Title</h2>
                        <h3>Subsection Title</h3>

Clear and Descriptive Labels for Form Fields

Use the <label> element to associate labels with form fields.

                            <form>
                            <label for="name">Name</label>
                            <input type="text" id="name" name="name">
                            <label for="email">Email Address</label>
                            <input type="email" id="email" name="email">

                            <input type="text" id="subject" name="subject">
                            <label for="message">Message</label>
                            <textarea id="message" name="message"></textarea>
                            </form>

Accessible Navigation Menus

                            <nav>
