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 HTML AAM .

Each language feature (element) in a cell in the first column implies the ARIA semantics (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 a 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

While setting an ARIA role and/or aria-* attribute that matches the implicit ARIA semantics is NOT RECOMMENDED , in some situations explicitly setting these attributes can be helpful. For instance, in user agents which lack exposing specific implicit ARIA semantics.

Rules of ARIA attribute usage by HTML element

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.

Example 6

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:

Document conformance requirements for use of ARIA attributes with HTML attributes

Unless otherwise stated, authors MAY use aria-* attributes in place of their HTML equivalents on HTML elements where the aria-* semantics would be expected. For example, authors MAY use aria-disabled=true on a button rather than the disabled attribute. However, authors SHOULD NOT use both the native HTML attribute and the aria-* attribute together. As stated in WAI- ARIA 's Conflicts with Host Language Semantics , user agents MUST ignore WAI- ARIA attributes and use the host language (HTML) attribute with the same implicit ARIA semantics .

The following table represents HTML elements and their attributes which have aria-* attribute parity.

Each language feature (element and attribute) in a cell in the first column implies the ARIA semantics (states, and properties) given in the cell in the second column of the same row. The third cell in each row defines how authors can use the native HTML feature, along with requirements for using the aria-* attributes that supply the same implicit ARIA semantics .

Rules of ARIA attribute usage by HTML feature
HTML feature	Implicit ARIA semantics	HTML feature and `aria-*` attribute author guidance
Any element where the `checked` attribute is allowed	`aria-checked="true"`	Use the `checked` attribute on any element that is allowed the `checked` attribute in HTML. Authors SHOULD NOT use the `aria-checked` attribute on any element where the checkedness of the element can be in opposition to the current value of the `aria-checked` attribute . Authors MAY use the `aria-checked` attribute on any other element with a WAI- ARIA role which allows the attribute.
Any element where the `disabled` attribute is allowed	`aria-disabled="true"`	Use the `disabled` attribute on any element that is allowed the `disabled` attribute in HTML. Authors MAY use the `aria-disabled` attribute on any element that is allowed the `disabled` attribute in HTML, or any element with a WAI- ARIA role which allows the `aria-disabled` attribute . Authors SHOULD NOT use `aria-disabled="true"` on any element which also has a `disabled` attribute. Authors MUST NOT use `aria-disabled="false"` on any element which also has a `disabled` attribute.
Any element with a `hidden` attribute	`aria-hidden="true"`	Authors MAY use the `aria-hidden` attribute on any HTML element, with the following exceptions: Authors SHOULD NOT use the `aria-hidden` attribute on any element which also has a `hidden` attribute. Authors MUST NOT use `aria-hidden="true"` on an element that can still receive keyboard focus, or on an ancestor element to an element or elements which can still receive keyboard focus. Any elements which can receive keyboard focus, interactive elements or otherwise, MUST have their ability to receive keyboard focus removed while the `aria-hidden="true"` attribute is present. For instance, by using `tabindex="-1"` on any focusable elements with `aria-hidden="true"`, or setting `tabindex="-1"` to focusable elements that are descendants of an `aria-hidden="true"` containing element.
Any element where the `placeholder` attribute is allowed	`aria-placeholder="..."`	Use the `placeholder` attribute on any element that is allowed the `placeholder` attribute in HTML. Authors MAY use the `aria-placeholder` attribute on any element that is allowed the `placeholder` attribute in HTML, or any element with a WAI- ARIA role which allows the `aria-placeholder` attribute . Authors MUST NOT use the `aria-placeholder` attribute on any element which also has a `placeholder` attribute.
Any element where the `max` attribute is allowed	`aria-valuemax="..."`	Use the `max` attribute on any element that is allowed the `max` attribute in HTML. It is NOT RECOMMENDED to use the `aria-valuemax` attribute on these elements. Authors MAY use the `aria-valuemax` attribute on any other element with a WAI- ARIA role which allows the attribute. Authors SHOULD NOT use `aria-valuemax` on any element which also has a `max` attribute, even if the values of each attribute match. Authors MUST NOT use `aria-valuemax` on any element which also has a `max` attribute, and the values of each attribute do not match.
Any element where the `min` attribute is allowed	`aria-valuemin="..."`	Use the `min` attribute on any element that is allowed the `min` attribute in HTML. It is NOT RECOMMENDED to use the `aria-valuemin` attribute on these elements. Authors MAY use the `aria-valuemin` attribute on any other element with a WAI- ARIA role which allows the attribute. Authors SHOULD NOT use `aria-valuemin` on any element which also has a `min` attribute, even if the values of each attribute match. Authors MUST NOT use `aria-valuemin` on any element which also has a `min` attribute, and the values of each attribute do not match.
Any element where the `readonly` attribute is allowed	`aria-readonly="true"`	Use the `readonly` attribute on any element that is allowed the `readonly` attribute in HTML. Authors MAY use the `aria-readonly` attribute on any element that is allowed the `readonly` attribute in HTML, or any element with a WAI- ARIA role which allows the `aria-readonly` attribute . Authors SHOULD NOT use the `aria-readonly="true"` on any element which also has a `readonly` attribute. Authors MUST NOT use `aria-readonly="false"` on any element which also has a `readonly` attribute.
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"`	Authors MUST NOT set `aria-readonly="true"` on an element that has `isContentEditable="true"`.
Any element where the `required` attribute is allowed	`aria-required="true"`	Use the `required` attribute on any element that is allowed the `required` attribute in HTML. Authors MAY use the `aria-required` attribute on any element that is allowed the `required` attribute in HTML, or any element with a WAI- ARIA role which allows the `aria-required` attribute . Authors SHOULD NOT use the `aria-required="true"` on any element which also has a `required` attribute. Authors MUST NOT use `aria-required="false"` on any element which also has a `required` attribute.
Any element where the `colspan` attribute is allowed	`aria-colspan="..."`	Use the `colspan` attribute on any element that is allowed the `colspan` attribute in HTML. Authors MAY use the `aria-colspan` attribute on any element that is allowed the `colspan` attribute in HTML, or any element with a WAI- ARIA role which allows the `aria-colspan` attribute . Authors SHOULD NOT use the `aria-colspan` attribute on any element which also has a `colspan` attribute. Authors MUST NOT use `aria-colspan` on any element which also has a `colspan` attribute, and the values of each attribute do not match.
Any element where the `rowspan` attribute is allowed	`aria-rowspan="..."`	Use the `rowspan` attribute on any element that is allowed the `rowspan` attribute in HTML. Authors MAY use the `aria-rowspan` attribute on any element that is allowed the `rowspan` attribute in HTML, or any element with a WAI- ARIA role which allows the `aria-rowspan` attribute . Authors SHOULD NOT use the `aria-rowspan` attribute on any element which also has a `rowspan` attribute. Authors MUST NOT use `aria-rowspan` on any element which also has a `rowspan` attribute, and the values of each attribute do not match.
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 .

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

<!-- conformance checkers will report an error -->
<button>
<div role="button">...</div>
</button>
<div role="button">
<button>...</button>
</div>
<div role="link">
<textarea>...</textarea>
