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 1.2 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) 1.2 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 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, MUST NOT, and SHOULD 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].

3.4 Exposing HTML Features That Require a Minimum Role

A minimum role is the equivalent WAI-ARIA role an element will map to if the element does not have a more specific implicit role or platform role mappings, e.g., a non-generic role. This can help ensure that users of assistive technologies get the best possible experience for commonly-used and valid HTML markup where otherwise a role would not be exposed.

A minimum role is provided when all of the following conditions are true:

The HTML Attribute State and Property Mappings section identifies the specific global attributes which would require an element map to a minimum role.

When these conditions are met, the browser MUST expose an object using the mappings defined in CORE-AAM for the specified minimum role. If the element has multiple attributes specified which require a minimum role be returned as the computed role for the element, prioritize the more specific role in the ARIA taxonomy.

3.5 HTML Element Role Mappings

3.5.1 Platform API mapping requirements

  • When HTML elements do not have an exact or equivalent mapping to a valid, non-abstract WAI-ARIA role, a unique computedrole string has been specified to serve as the return value for interoperability testing purposes. For instance, the video element MAY be exposed with a computedrole of "html-video". Authors MUST NOT use any html-prefixed computed role string in the role attribute (such as html-video). User Agents MUST ignore any abstract or invalid role token.
    <video> <!-- computedrole returns 'html-video' --> <main role="html-video"> <!-- Author error. computed role returns 'main' -->
  • IAccessible2:
    • All elements with accessible objects should implement the IAccessible, IAccessible2 and IAccessible2_2 interfaces.
  • UIA:
    • When a labelable element is referenced by a label element's for attribute, or a descendant of a label element, the labelable element's UIA LabeledBy property points to the UIA element for the label element.
    • Elements mapped to the Text Control Type are not generally represented as accessible objects in the accessibility tree, but are just part of the Text Control Pattern implemented for the whole HTML document. However, if they have any aria- attributes or an explicit tabindex specified, elements mapped to the Text Control Type will be represented as accessible objects in the accessibility tree.
  • AXAPI:
    • User agents should return a user-presentable, localized string value for the Mac Accessibility AXRoleDescription.

If the element includes both the required attribute and the aria-required attribute with a valid value, User Agents MUST expose only the required attribute value.

If an element is required, user agents MUST NOT expose the element with an intitial invalid state (aria-invalid="true"). The user agent SHOULD expose the invalid state only after 1) a user has purposefully interacted with a required element, or attempted to submit a form and 2) the element, or elements, do not meet constraint validation.

Until these conditions are met, user agents MUST expose the elements as (aria-invalid="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.

Note

User Agents notify assistive technology when relevant accessibility information changes, sometimes by destroying and recreating the accessibility object, or sometimes by notifying of changes to the object per the specified name change event mappings and description change event mappings.

4.1 Accessible Name Computations By HTML Element

4.1.1 input type="text", input type="password", input type="number", 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 or elements 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 value.
  5. If none of the above yield a usable text string there is no accessible name.

4.1.2 input type="button", input type="submit" and input type="reset" 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. Otherwise use the value attribute.
  4. For input type=submit and type=reset: if the prior steps do not yield a usable text string, and the value attribute is unspecified use the implementation defined string respective to the input type.
  5. Otherwise, if the control still has no accessible name use title attribute.
  6. If none of the above yield a usable text string there is no accessible name.

4.1.3 input type="image" 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. Otherwise use alt attribute if present and its value is not the empty string.
  4. Otherwise use title attribute if present and its value is not the empty string.
  5. Otherwise if the previous steps do not yield a usable text string, use the implementation defined string respective to the input type (an input in the image state represents a submit button). For instance, a localized string of the word "submit" or the words "Submit Query".
  6. If none of the above yield a usable text string there is no accessible name.

4.1.4 button Element Accessible Name Computation

  1. If the button element 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. Otherwise use the button element subtree.
  4. Otherwise use title attribute.
  5. If none of the above yield a usable text string there is no accessible name.

4.1.5 fieldset Element Accessible Name Computation

  1. If the fieldset element 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. If the accessible name is still empty, then: if the fieldset element has a child that is a legend element, then use the subtree of the first such element.
  3. If the accessible name is still empty, then:, if the fieldset element has a title attribute, then use that attribute.
  4. Otherwise, there is no accessible name.

4.1.6 output Element Accessible Name Computation

  1. If the output element 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 or elements accessible name(s) - if more than one label is associated; concatenate by DOM order, delimited by spaces.
  3. Otherwise use title attribute.
  4. If none of the above yield a usable text string there is no accessible name.

4.1.7 Other Form Elements 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 label element.
  3. Otherwise use title attribute.
  4. If none of the above yield a usable text string there is no accessible name.

4.1.8 summary Element Accessible Name Computation

  1. If the first summary element, which is a direct child of the details element, 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 summary element subtree.
  3. Otherwise use title attribute.
  4. If there is no summary element as a direct child of the details element, the user agent should provide one with a subtree containing a localized string of the word "details".
  5. If there is a summary element as a direct child of the details element, but none of the above yield a usable text string, there is no accessible name.

4.1.9 figure Element Accessible Name Computation

  1. If the figure element 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. If the accessible name is still empty, then: if the figure element has a child that is a figcaption element, then use the subtree of the first such element.
  3. If the accessible name is still empty, then: if the figure element has a title attribute, then use that attribute.
  4. Otherwise, there is no accessible name.

4.1.10 img Element Accessible Name Computation

  1. If the img element 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 alt attribute, even if its value is the empty string.
    Note
    An img with an alt attribute whose value is the empty string is mapped to the presentation role. It has no accessible name.
  3. Otherwise, if there is no alt attribute use the title attribute.
  4. Otherwise there is no accessible name.

4.1.11 table Element Accessible Name Computation

  1. If the table element 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.

  3. If none of the above yield a usable text string there is no accessible name.

4.2 Accessible Description Computation

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.

  1. If the element has an aria-describedby or aria-description attribute refer to the computation conditions defined in Accessible Name and Description: Computation and API Mappings.
  2. Otherwise, if the accessible description is still empty, and the element is:
  3. Otherwise, use the flat string of the title attribute if it was not used as the accessible name for the element.
  4. If none of the above are applicable, there is no accessible description.

5. Privacy considerations

In accordance with Web Platform Design Principles, this specification provides no programmatic interface to determine if information is being used by Assistive Technologies. However, this specification does allow an author to present different information to users of Assistive Technologies from the information available to users who do not use Assistive Technologies. This is possible using many features of the ARIA and CORE-AAM specifications, just as this is possible using many other parts of the web technology stack. This content disparity could be abused to perform active fingerprinting of users of Assistive Technologies.

6. Security considerations

This specification introduces no new security considerations.
