ARIA in HTML

Abstract

This specification defines the web developer rules (author conformance requirements) for the use of Accessible Rich Internet Applications (WAI-ARIA) 1.1 and Digital Publishing WAI-ARIA Module 1.0 attributes on [HTML] elements. It also defines requirements for Conformance Checking tools.

2. Document conformance requirements for use of ARIA attributes in HTML

The following table provides normative per-element document-conformance requirements for the use of ARIA markup in HTML documents and describes the implicit ARIA semantics that apply to HTML elements as defined in the HTML Accessibility API Mappings 1.0 [html-aam-1.0] specification.

Each language feature (element or attribute) in a cell in the first column implies the ARIA semantics (any role, states, and properties) given in the cell in the second column of the same row. The third cell in each row defines which ARIA role values and aria-* attributes which MAY be used. Where a cell in the third column includes the term Any role it indicates that any role value apart from the implicit ARIA semantics role value, MAY be used. If an cell in the third column includes the term No role it indicates that authors MUST NOT overwrite the implicit ARIA semantics, or native semantics of the HTML element.

Note

Setting an ARIA role and/or aria-* attribute that matches the implicit ARIA semantics is unnecessary and is NOT RECOMMENDED as these properties are already set by the browser.

Rules of ARIA attribute usage by HTML feature

Element with a `placeholder` attribute	`aria-placeholder=""`	Use the `placeholder` attribute on any element that is allowed the `placeholder` attribute in HTML. Only use the `aria-placeholder` attribute on elements that are not allowed to have a `placeholder` attribute in HTML.
Element with a `required` attribute	`aria-required="true"`	Use the `aria-required` attribute on any element that is allowed the `required` attribute in HTML. MUST NOT be set to `false` if the `required` attribute is set. MAY also be used for elements that have an ARIA role which allows the `aria-required` attribute.
Element with a `readonly` attribute	`aria-readonly="true"`	Use the `readonly` attribute on any element that is allowed the `readonly` attribute in HTML. Only use the `aria-readonly` attribute for elements that are not allowed to have a `readonly` attribute in HTML.
Element with a `hidden` attribute	`aria-hidden="true"`	Use the `aria-hidden` attribute on any HTML element. Note: If an element has a `hidden` attribute, an `aria-hidden` attribute is not required.
Element that is a candidate for constraint validation but that does not satisfy its constraints	`aria-invalid="true"`	The `aria-invalid` attribute may be used on any HTML element that allows global `aria-*` attributes except for a submittable element that does not satisfy its validation constraints.
Element with `contenteditable="true"`; or Element without `contenteditable` attribute whose closest ancestor with a `contenteditable` attribute has `contenteditable="true"`. Note: this is equivalent to the `isContentEditable` IDL attribute.	`aria-readonly="false"`	Do not set `aria-readonly="true"` on an element that has `isContentEditable="true"`.

The elements marked with No corresponding role, in the second column of the table do not have any implicit ARIA semantics, but they do have meaning and this meaning may be represented in roles, states and properties not provided by ARIA, and exposed to users of assistive technology via accessibility APIs. It is therefore recommended that web developers add a role attribute to a semantically neutral element such as a div or span, rather than overriding the semantics of the listed elements.

Note

Authors are encouraged to make use of the following documents for guidance on using ARIA in HTML beyond that which is provided here:

Using ARIA - A practical guide for developers on how to add accessibility information to HTML elements using the Accessible Rich Internet Applications specification (ARIA 1.1).
WAI-ARIA Authoring Practices 1.2 - An author's guide to understanding and implementing Accessible Rich Internet Applications.

Example 2

These features can be used to make accessibility tools render content to their users in more useful ways. For example, ASCII art, which is really an image, appears to be text, and in the absence of appropriate roles and properties would end up being rendered by screen readers as a nonsensical string of punctuation characters. Using the features described in this section, one can instead make the ATs skip the ASCII art and just read the caption:

<figure>
  <pre role="img">
  o           .'`/
    '      /  (
  O    .-'` ` `'-._      .')
      _/ (o)        '.  .' /
      )       )))     ><  <
      `\  |_\      _.'  '. \
        '-._  _ .-'       '.)
    jgs     `\__\
  </pre>

4. Allowed ARIA roles, states and properties

Columns 1 to 4 of the ARIA Roles, States and Properties table provide an informative (non-normative) reference to the ARIA roles, states and properties permitted for use in HTML. All ARIA roles, states and properties are normatively defined in the Accessible Rich Internet Applications (WAI-ARIA) 1.1 specification. Links to ARIA roles, states and properties in the table reference the normative Accessible Rich Internet Applications (WAI-ARIA) 1.1 definitions.

Column 5 of the ARIA Roles, States and Properties table, defines extensions to the Kinds of content (defined in the [HTML] specification) categories each role has when it is used on a HTML element. Column 6 defines what HTML elements can be descendants of an element with a particular implicit or explicit role value.

For example, an element with role=button is interactive content and therefore cannot contain interactive content descendants. A button element has an implicit role=button, so cannot contain any elements with role values that are in the interactive content category (identified in Column 3).

Examples of non-conforming descendants

<button>
<div role="button">...</div>
</button>

<div role="button">
<button>...</button>
</div>

<div role="link">
