ARIA: region role

The region role is used to identify document areas the author deems significant. It is a generic landmark available to aid in navigation when none of the other landmark roles are appropriate.

<div role="region" aria-label="Example">
  <!-- region content -->
</div>

Description

The region role is an ARIA landmark role. The region role should be reserved for sections of content sufficiently important that users will likely want to navigate to the section easily and to have it listed in a summary of the page. A region role is a more generic term, and should only be used if the section needing to be identified is not accurately described by one of the other landmark roles, such as banner, main, contentinfo, complementary, or navigation.

Every element with a region role should include a label that describes the purpose of the content in the region, preferably with an aria-labelledby referencing a visible header. If no visible appropriate header is present, aria-label should be used.

The region landmark role's content should make sense if separated from the main content of the document.

Using the <section> element will automatically communicate a section has a role of region if it is given an accessible name. Developers should always prefer using the correct semantic HTML element, in this case <section>, over using ARIA.

aria-labelledby or aria-label: Use this attribute to label the region. Often, the value of the aria-labelledby attribute will be the id of the element used to title the section. If no visible appropriate header is present, aria-label should be used.

Examples

<div role="region" aria-labelledby="region-heading">
  <h2 id="region-heading">
    This heading's `id` attribute helps this region have an accessible name
  </h2>
  <!-- region content -->
</div>

Accessibility concerns

Use sparingly! Landmark roles are intended to be used sparingly, to identify larger overall sections of the document. Using too many landmark roles can create "noise" in screen readers, making it difficult to understand the overall layout of the page.

Only use the region role if no other relevant content sectioning element or landmark role applies. If multiple regions exist on a page, it may be worth reinvestigating the page's overall structure.

Best practices

Prefer HTML

Using the <section> element will automatically communicate that a section has a role of region if it is given an accessible name. If at all possible, prefer using <section> instead.

Labeling landmarks

If there is more than one region landmark role in a document, provide a unique label for each one. This label will allow an assistive technology user to be able to quickly understand the purpose of each landmark.

<div role="region" aria-labelledby="use-discretion">
  <h3 id="use-discretion">Please use the `region` role with discretion</h3>
  <!-- content -->
</div>

…

<div role="region" aria-labelledby="please-reconsider">
  <h3 id="please-reconsider">Please reconsider your document structure</h3>
  <!-- content -->
</div>

In this example, the region's label is being generated by the aria-labelledby attribute.
