Abstract

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 Accessibility API Mappings 1.2 and the Accessible Name and Description Computation 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.

1. Introduction

This section is non-normative.

This specification defines how HTML user agents 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 semantics must be exposed to the platform accessibility APIs according to the relevant WAI-ARIA mappings defined in the Core Accessibility API Mappings 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 Accessible Name and Description Computation 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:

1.1 Accessibility APIs

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 1.2.

2. Conformance

As well as sections marked as non-normative, all authoring guidelines, diagrams, examples, and notes in this specification are non-normative. Everything else in this specification is normative.

The key words MAY, MUST, and MUST NOT in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.

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.

2.1 Deprecated

There are currently no deprecated requirements.

3. Mapping HTML to Accessibility APIs

3.1 General Rules for Exposing WAI-ARIA Semantics

Note

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 Accessibility API Mappings 1.2.

3.2 Conflicts Between Native Markup Semantics and WAI-ARIA

Where the host language is [HTML], user agents MUST conform to Conflicts between native markup semantics and WAI-ARIA in the Core Accessibility API Mappings 1.2.

3.3 Exposing HTML Features That Do Not Directly Map to Accessibility APIs

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].

The open attribute's value is irrelevant. When the open attribute is not specified the default user agent styling for a dialog is display: none.

Authors can reveal a dialog through the style layer by modifying its display property. If revealed this way then the dialog is aria-modal="false" and aria-hidden="false".

Comments
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.

4. Accessible Name and Description Computation

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.

4.1 input type="text", input type="password", input type="search", input type="tel", input type="url" and textarea Element

4.1.1 input type="text", input type="password", input type="search", input type="tel", input type="email", input type="url" and textarea Element Accessible Name Computation

  1. If the control has an aria-label or an aria-labelledby attribute the accessible name is to be calculated using the algorithm defined in Accessible Name and Description: Computation and API Mappings.
  2. Otherwise use the associated label element(s) accessible name(s) - if more than one label is associated; concatenate by DOM order, delimited by spaces.
  3. If the accessible name is still empty, then: use the control's title attribute.
  4. Otherwise use the control's placeholder attribute.
  5. If none of the above yield a usable text string there is no accessible name.

4.1.2 input type="text", input type="password", input type="search", input type="tel", input type="email", input type="url" and textarea Element Accessible Description Computation

  1. If the element has an aria-describedby attribute the accessible description is to be calculated using the algorithm defined in Accessible Name and Description: Computation and API Mappings.
  2. Otherwise use the title attribute if it wasn't used as the accessible name.

  4. For input type=reset: If steps 1 to 2 do not yield a usable text string, the accessible name is a localized string of the word "reset".
  5. Otherwise use title attribute.
  6. If none of the above yield a usable text string there is no accessible name.

4.2.2 input type="button" , input type="submit" and input type="reset" Accessible Description Computation

  1. If the element has an aria-describedby attribute the accessible description is to be calculated using the algorithm defined in Accessible Name and Description: Computation and API Mappings.
  2. Otherwise use the value attribute if it wasn't used as the accessible name.
