HTML Accessibility API Mappings (HTML-AAM) defines how user agents map HTML [[HTML]] elements and attributes to platform accessibility application programming interfaces (APIs). It leverages and extends the [[[core-aam-1.2]]] and the [[[accname-aam-1.1]]] for use with the HTML host language. Documenting these mappings promotes interoperable exposure of roles, states, properties, and events implemented by accessibility APIs and helps to ensure that this information appears in a manner consistent with author intent.
The HTML-AAM is part of the WAI-ARIA suite described in the WAI-ARIA Overview.
This document is subject to change without notice.
This document was initially developed by and with the approval of the HTML Accessibility Taskforce, a joint task force of the Protocols and Formats Working Group and the HTML Working Group. Work continued with the successor groups Accessible Rich Internet Applications Working Group and the Web Applications Working Group. This document is now maintained solely by the Accessible Rich Internet Applications Working Group.
This specification defines how HTML user agents respond to and expose [=role=], [=state=] and [=ARIA/property=] information provided for Web content. Unless indicated otherwise, an HTML element or attribute with default [[[WAI-ARIA]]] semantics must be exposed to the platform accessibility APIs according to the relevant WAI-ARIA mappings defined in the [[[core-aam-1.2]]] ([[core-aam-1.2]]) specification.
In some cases, often due to features of the HTML host language or the accessibility API in question, an element or attribute's mapping differs from the corresponding ARIA mappings specified in the [[core-aam-1.2]]. Where an HTML element or attribute does not have any default WAI-ARIA semantics, the applicable mapping for each platform accessibility API is defined by this specification.
This document also adapts the [[[accname-1.2]]] specification for deriving the accessible names and accessible descriptions of [[HTML]] elements, and provides accessible implementation examples for specific HTML elements and features.
Users often access HTML content using assistive technologies that rely on platform accessibility API to obtain and interact with information from the page. This document is part of the following suite of accessibility API mapping specifications for content rendered by user agents:
Accessibility APIs covered by this document are:
If user agent developers need to expose information using other accessibility APIs, it is recommended that they work closely with the developer of the platform where the API runs, and assistive technology developers on that platform.
For more information regarding accessibility APIs, refer to section 1.1 Accessibility APIs of the [[[core-aam-1.2]]].
The classification of a section as normative or non-normative applies to the entire section and all sub-sections of that section.
Normative sections provide requirements that authors, user agents, and assistive technologies MUST follow for an implementation to conform to this specification.
Non-normative sections provide information useful to understanding the specification. Such sections may contain examples of recommended practice, but it is not required to follow such recommendations in order to conform to this specification.
There are currently no deprecated requirements.
WAI-ARIA support was first introduced to HTML in [[HTML5]].
Where an HTML element or attribute has default WAI-ARIA semantics, it MUST be exposed to the platform accessibility APIs in a way that conforms to General rules for exposing WAI-ARIA semantics in the [[[core-aam-1.2]]].
Where the host language is [[HTML]], user agents MUST conform to Conflicts between native markup semantics and WAI-ARIA in the [[[core-aam-1.2]]].
HTML can include features that are not supported by accessibility APIs at the time of publication. There is not a one to one relationship between all features and platform accessibility APIs. When HTML roles, states and properties do not directly map to an accessibility API, and there is a method in the API to expose a text string, user agents MUST expose the undefined role, states and properties via that method.
For HTML elements or attributes with default WAI-ARIA semantics, user agents MUST conform to Exposing attributes that do not directly map to accessibility API properties in the [[core-aam-1.2]].

|
Some platforms (IAccessible2, ATK, UIA) do not expose an accessible object for the list item marker, whether it was created and then pruned from the accessibility tree, or never created in the first place. Instead, they expose the list item marker as part of the associated list item's accessible text. In these cases, implementors need to consider such things as adjusting the offsets (e.g., for caret-moved events, text-selection events, etc.) for the updated list item text that now also contains the list item marker as content, rather than just taking the offsets unmodified from the list item renderer.

The terms accessible name and accessible description are properties provided in all accessibility APIs. The name of the properties may differ across APIs but they serve the same function: as a container for a short (name) or longer (description) string of text.
The text alternative computation is used to generate both the accessible name and accessible description. There are different rules provided for several different types of elements, nodes, and combinations of markup.
legend element, then use the subtree of the first such element.
caption element, then use the subtree of the first such element.
The document referenced by the `src` of the `iframe` element gets its name from that document's `title` element, like any other document. If there is no `title` provided, there is no accessible name.

An accessible description MAY be provided to any HTML element that is a valid child of the `body` element. The following list represents the order of precedence for user agents to compute the accessible description of an element. As defined by Accessible Name and Description Computation: Description Computation , user agents MUST use the first applicable description source, even if its use results in an empty description.
