HTML Accessibility API Mappings (HTML-AAM) defines how user agents map HTML 5.2 [[!HTML52]] elements and attributes to platform accessibility application programming interfaces (APIs). It leverages and extends the Core Accessibility API Mappings 1.1 [[!CORE-AAM]] and the Accessible Name and Description: Computation and API Mappings 1.1 [[!ACCNAME-AAM]] for use with the HTML 5.2 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 Platform Working Group. The document is now maintained solely by the Web Platform WG.
This specification defines how HTML user agents must respond to and expose role, state and property information provided for Web content. Unless indicated otherwise, an HTML element or attribute with default Accessible Rich Internet Applications (WAI-ARIA) 1.1 [[!WAI-ARIA]] semantics must be exposed to the platform accessibility APIs according to the relevant WAI-ARIA mappings defined in the Core Accessibility API Mappings [[!CORE-AAM]] 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]]. 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 Accessible Name and Description: Computation and API Mappings [[!ACCNAME-AAM]] for deriving the accessible names and accessible descriptions of HTML 5.1 [[!HTML51]] elements, and provides accessible implementation examples for specific HTML 5.1 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 Accessibility API Mappings [[!CORE-AAM]].
These RFC2119 key words are formatted in uppercase and contained in a strong element with class="rfc2119". When these key words are used, but do not share this format, they do not convey any formal conformance requirements in the RFC2119 sense, and are merely explanatory, i.e., informative. As much as possible, such usage is avoided in this specification.
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.
WAI-ARIA support was first introduced to HTML in HTML5 [[!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 Accessibility API Mappings [[!CORE-AAM]].
Where the host language is HTML 5.1 [[!HTML51]], user agents MUST conform to Conflicts between native markup semantics and WAI-ARIA in the Core Accessibility API Mappings [[!CORE-AAM]].
HTML may have 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 Accessibility API Mappings [[!CORE-AAM]].
In MSAA, the value of an accessible object's Role property is retrieved with the IAccessible::get_accRole method. This method returns a VARIANT that is limited to a finite number of integer role constants insufficient for describing the role of every HTML element, especially new elements introduced by HTML5. To address this limitation, some user agents, e.g., Firefox and Chrome in cooperation with some screen readers, have elected to expose certain roles by returning a string value (BSTR) in that VARIANT in a way that is not described by the MSAA specification.
For example, Firefox returns the element's tag name as a BSTR for the following: abbr, address, aside, blockquote, canvas, caption, dd, div, figcaption, footer, form, h1–h6, header, iframe, input type="file", main, menu, nav, output, p, pre, q, section, time.
Similarly, Chrome returns the element's tag name for: blockquote, div, dl, figcaption, form, h1-h6, menu, meter, p, pre.

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.

The details element should not focusable by default.
Pressing the spacebar or enter key when the summary element has focus will show the details element content if the content is hidden. If the details element content is showing and the summary element has focus, pressing the spacebar or enter key will hide the details element content.
The summary element should be mapped to a disclosure triangle role in accessibility APIs that have such a role. For example the Mac accessibility API includes the AXDisclosureTriangle role. In accessibility APIs that do not have such a fine grained role, the summary element should be mapped to a button role. The role mapping table contains recommended mappings for the summary element.
The default accessible name for the summary element is the text content of the summary element.
When the details element content is hidden, the state of the content should be reflected by an accessible state or property.
Example 1: In the Mac accessibility API on the summary element (AXDisclosureTriangle), set AXExpanded property to NO. When the details element content is shown, on the summary element (AXDisclosureTriangle), set theAXExpanded property to YES. The hidden and shown states of the details element content is reflected by the absence or presence of the open attribute.
Example 2: In the IA2 accessibility API on the summary element (ROLE_SYSTEM_PUSHBUTTON), set STATE_SYSTEM_COLLAPSED. When the details element content is shown, on the summary element (ROLE_SYSTEM_PUSHBUTTON), set STATE_SYSTEM_EXPANDED. The hidden and shown states of the details element content is reflected by the absence or presence of the open attribute.
