You may see section while reading an accessibility specification. It is an abstract ARIA role: a category used to organize the role system, not a label that should be added to your website.
What this role means
An abstract family of structural roles.
Abstract roles explain relationships between real roles. A browser cannot turn role="section" into a useful accessible control, so the specification tells authors not to use it directly.
Use a real HTML element instead
<section aria-labelledby="chapter-heading">
<h2 id="chapter-heading">Chapter 2</h2>
</section>Read the example
The snippet deliberately shows an actual HTML element or more specific widget, not the abstract role. That is the important lesson: choose markup that has a real purpose and behavior.
Do not use role="section"; use section with an appropriate heading.
When to use it
When you find section in a role hierarchy, ask which concrete role describes your interface. For example, an ordinary action is normally a <button>, and a page navigation area is a <nav>.
In an accessibility inspector, compare the accessible role and name with the visible content. The important goal is that both keyboard users and screen-reader users can understand the page.
Try it yourself
Put the example on a practice page and inspect it using your browser accessibility panel. If it includes interactive controls, reach them with Tab and check whether they work without a mouse. Explain whether the semantics come from native HTML or an explicit ARIA role.
Common Beginner Mistakes
- Copying
role="section"from a specification into a production webpage. - Do not use role="section"; use section with an appropriate heading.
- Confusing the role announced by a screen reader with the behavior that the browser implements.
Key Takeaways
sectionis related to an abstract family of structural roles.- Do not use role="section"; use section with an appropriate heading.
- Native HTML is the first choice; ARIA should clarify meaning, not replace working HTML.
