When you build web pages, making them accessible to everyone—including people using screen readers or assistive technologies—is essential. Two key concepts in accessibility are using a logical heading order and applying ARIA (Accessible Rich Internet Applications) roles. Headings help users understand the structure of your content, while ARIA roles provide extra meaning to elements that might not be inherently semantic. Using these tools correctly ensures that your pages are not only readable but also navigable for all users.

In this example, the heading order starts with a single h1 for the page title, followed by h2 headings for major sections, and h3 for subsections. This logical order helps screen readers and users quickly understand the page hierarchy. ARIA roles like role="article" and role="contentinfo" clarify the purpose of elements for assistive technologies, while attributes such as aria-label and aria-labelledby provide accessible names for navigation and sections.
