An in-depth guide to ARIA roles

The ARIA specification is divided into categories of attributes, one of which is Roles, and the other being States & Properties. ARIA roles, which are covered in this article, are generally used to describe elements:

  • that may not exist within HTML,
  • which may not have full cross-browser support,
  • which may have implementation gaps in screen readers and other assistive technologies.

For instance, ARIA roles can be useful in situations where native HTML semantics are not understood in legacy user agents (e.g., browsers).


ARIA roles are added to elements using the role="<ROLE_TYPE>" attribute, where ROLE_TYPE represents the specific role being added. Once an ARIA role is set on an element, it should not be changed, regardless of the state of the element. In some cases, roles have to be paired with the appropriate ARIA state or property. However, this article's examples have reduced markup to limit the scope to just ARIA roles.

ARIA roles are broken down into six categories:

  1. Abstract Roles
  2. Document Structure Roles
  3. Landmark Roles
  4. Live Region Roles
  5. Widget Roles
  6. Window Roles

Abstract roles

Abstract roles are only intended for use by browsers to help organize and streamline a document. They should not be used by developers writing HTML markup. Doing so will not result in any meaningful information being conveyed to assistive technologies or to users.

Document Structure roles

Document roles are used to provide a structural description for a section of content. A majority of the available roles in this category resemble available semantic HTML tags and it is recommended to only use them when an appropriate native tag is not available. The roles in this category are also not typically interactive in nature. However, they may be used to contain other roles that are interactive. The following examples of toolbar and tooltip roles, serve as good examples of when to use Document Structure roles to provide information to assistive technologies when the equivalent native HTML tag is not available.

Toolbar example

<div role="toolbar">
<div class="text-characteristics">

<div class="text-alignment">

Tooltip example

<button aria-describedby="notifications-desc">Notifications</button>
<div role="tooltip" id="notifications-desc">View and manage notifications</div>

Landmark Roles

Landmark roles identify content areas within a page. They serve as navigational landmarks for the types of content areas that users may be interested in. These content areas include the page's primary content, collections of navigation links, and search functions to name a few.

Most Landmark roles are also implicitly exposed via specific Grouping and Sectioning HTML elements. For example:

  • The banner role can be associated with the <header> element
  • The complementary role can be associated with the <aside> element
  • The contentinfo role can be associated with the <footer> element

Refer to Quick Tip: ARIA Landmark roles and HTML5 implicit mapping for more details on the above mappings and browser support for them.

<nav role="navigation">
<li><a href="#a">Dexter</a></li>
<li><a href="#b">Doctor Who</a></li>
<li><a href="#c">Futurama</a></li>

Search role example

<form role="search">
<label for="search-input">Search this site</label>
<input type="text" id="search-input" name="search">
<input type="submit" name="submit-btn" value="Search" />
<footer role="contentinfo">

Live Region Roles

Live Region roles are used to inform assistive technologies, such as screen readers, of dynamic changes to page content, so that they can be announced to users. The reason for this is that dynamic changes may be visually noticeable, but likely will be missed by users with low or no vision.

Alert role example

The most commonly used Live Region role is the alert role.

<div role="alert">
<p>Autosave failed.</p>

When using the alert role, keep in mind that it should not be a focusable element and it should not require users to close it.

Widget Roles

Widget roles are used to describe common interactive patterns or those that currently lack semantic equivalents in HTML. In most cases, these interactive patterns will be JavaScript-driven. Widget roles should not be confused with role="widget" which is itself an abstract role.

Tabs role example

A common interactive pattern that relies on Widget roles is the very familiar Tabs pattern. Tabs rely on three Widget roles, namely tab, tabpanel, and tablist.

<div role="tablist" aria-label="Fruits">
<button role="tab" aria-selected="true" aria-controls="apples-tab" id="apples">Apples</button>
<button role="tab" aria-selected="false" aria-controls="oranges-tab" id="oranges">Oranges</button>

<div role="tabpanel" id="apples-tab" aria-labelledby="apples">
<p>Apples tab content</p>

<div role="tabpanel" id="oranges-tab" aria-labelledby="oranges">
<p>Oranges tab content</p>

The tablist role is a composite Widget role, which means it is a container used to manage other contained widgets. It is used to contain the list of tab elements, each of which is an interactive element. When a tab element is activated, it will cause its associated tabpanel container to display.

Window Roles

Window roles are used when creating sub-windows to the primary application or document. A typical example is a modal dialog. The available Window roles are alertdialog and dialog.

Alertdialog role example

An alertdialog is a dialog that contains an alert message and focus is initially set to an element within the dialog. While the dialog is visible, keyboard and mouse interactions are limited to the elements within the dialog.

<div role="alertdialog">

<p>Are you sure you want to discard all of your notes?</p>

<button type="button">No</button>
<button type="button">Yes</button>

Dialog role example

A dialog is a window that separates certain content or UI from the rest of the page. Like the alertdialog role, elements within the dialog can receive focus. While alertdialogs are more often than not modal (confining a user's interaction to the contents of the alert dialog until it is dismissed), a standard dialog can be modal or not. When not modal, people may be able to interact with the contents of the dialog, as well as the primary content of the page, freely.

<div role="dialog" aria-labelledby="dialog-label">
<h2 id="dialog-label">Dialog Title</h2>
<p>This is the dialog content.</p>

<button>Close Dialog</button>
