  • generated direct-develop head: f545159452d466afaeb5dfbc9aab0be4f86fcd88
  • canonical Settings native-disabled owner: fix(a11y): remove redundant aria-disabled from native disabled buttons #1676 exact 8a3ac51662fbe8e49f26a317ac0afe85f853c9ac
  • generated product delta: remove redundant aria-disabled from the same account-save and runner-token-rotation native buttons while retaining native disabled and aria-busy
  • canonical owner delta: the same production correction plus frontend/src/components/SettingsLayout.native-disabled.test.tsx and docs/doctoring/settings-native-disabled-accessibility.md

#1676 completely owns the valid product intent and is stronger than this generated PR. Its doctoring record also preserves the accessibility exception that this PR's generated .jules/palette.md guidance omitted: aria-disabled without native disabled remains valid when a control intentionally must stay discoverable/focusable, with activation suppressed separately. That distinction is also the still-valid CodeRabbit CHANGES_REQUESTED finding on this PR.

The live compare is divergent rather than ancestral, so no check/review/evidence is transferred by topology. Closure is justified only by complete semantic succession: every valid product/test/contract intent is already present in #1676; the only unique generated delta is the over-broad .jules guidance and is intentionally not inherited.

#1676 remains Draft and its hosted/browser/independent-review gates remain separate. Closing this PR is not acceptance evidence and does not authorize #1676 to merge.

Lifecycle: CLOSED UNMERGED — complete valid delta superseded by #1676; no remaining unique valid delta.

## 2024-05-25 - Avoid redundant aria-disabled on native disabled buttons
**Learning:** Using `aria-disabled` alongside the native HTML `disabled` attribute on `<button>` elements is a redundant accessibility anti-pattern. The native `disabled` attribute inherently communicates the unavailable state and manages focus correctly, while `aria-disabled` is typically only needed for custom semantic elements (like `div` acting as a button) that cannot use the native attribute.
**Action:** When managing disabled states for interactive elements (like buttons), rely solely on the native `disabled` attribute for state management. For async operations (e.g., loading or saving), combine it with `aria-busy="true"` to communicate active updates, but never apply `aria-disabled` simultaneously.

<title>Developing a Keyboard Interface | APG | WAI | W3C</title> https://www.w3.org/WAI/ARIA/apg/practices/keyboard-interface/ ## Focusability of disabled controls ... Browsers remove HTML input elements with the`disabled` attribute from the tab sequence. However, there are some contexts where it is useful for an element to convey a disabled state while remaining focusable, especially inside of composite widgets. This can be accomplished by applying the state`aria-disabled="true"`. For example, as demonstrated in the menu and menubar pattern, disabled items are focusable when navigating through a menu with the arrow keys. ... task. However, screen reader users are far less likely ... able because moving ... Authors are encouraged to adopt consistent pattern-based conventions for the focusability of disabled elements. The examples in this guide adopt the following conventions, which both reflect common practice and attempt to balance competing concerns. ... 1. When users can reasonably infer the presence of a disabled element from nearby focusable elements, it is removed from the keyboard focus order using the HTML`disabled` attribute. For example: ... - A toolbar with buttons for moving, removing, and adding items in a list includes buttons for "Up", "Down", "Add", and "Remove". The "Up" button is disabled and its focusability is removed when the first item in the list is selected. Given the presence of the "Down" button, discoverability of the "Up" button is not a concern. ... 3. When a disabled element does need to remain discoverable,`aria-disabled="true"` is applied so that it will remain focusable. For example: ... 4. - The “Copy”, “Cut”, and “Paste” buttons in the Toolbar. The discoverability of these features relies on their focusability even when they are not immediately applicable (i.e., when no text is selected in the editor and/or when the clipboard is empty). ... - Options in a Listbox - Menu items in a Menu or menu bar - Tab elements in a set of Tabs - Tree items in a Tree View ... One design technique for mitigating the impact of including disabled elements in the path of keyboard focus is employing appropriate ... shortcuts as described in Keyboard Shortcuts. <title>ARIA: aria-disabled attribute - ARIA | MDN</title> https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Reference/Attributes/aria-disabled The `aria-disabled` state indicates that the element is perceivable but disabled, so it is not editable or otherwise operable. ... The `aria-disabled` attribute, when set to `true`, indicates that the element upon which it is set and all of its focusable descendants are meant to be in the disabled state. This declaration will inform people using assistive technologies, such as screen readers, that such elements are not meant to be editable or otherwise operable. ... Unlike HTML&`#39`;s `disabled` Boolean attribute, which will communicate a form control as semantically being disabled, change its styling to reflect its state and suppress all functionality along with disallowing the element&`#39`;s value from participating in form submission, the `aria-disabled="true"` only semantically exposes these elements as being disabled. Web developers must manually ensure such elements have their functionality suppressed when exposed to the disabled state. ... When needing to disable native HTML form controls, developers will need to specify the `disabled` attribute, as it provides all of the generally expected features of disabling a control by default. However, there can be instances where elements need to be exposed as disabled, but are still available for users to find when navigating via the Tab key. Doing so can improve their discoverability as they will not be removed from the focus order of the web page, as `aria-disabled` does not change the focusability of such elements, nor will the elements be dimmed by default browser styling, making them easier to read. Some examples of where this may be useful include: ... - The header button element associated with non-collapsible accordion panel, - A button which is important to keep in the page&`#39`;s focus order, but its action is presently unavailable - such as submitting a form, - Temporarily inactive items in a menu widget that would otherwise be skipped over via standard keyboard navigation. ... In each of these cases, one may want users to find these elements through standard keyboard navigation, though the functionality of that control is removed or "disabled". Developers will still need to use JavaScript to fully disable the functionality of the element while also changing the appearance of the element so sighted users know it is disabled. ... Note: The state of being disabled applies to the element with `aria-disabled="true"` and all of its focusable descendants. Take care when using this attribute on container elements. Particularly in the case where a container may have both form controls and links - where the intent may be to expose the form controls as being in the disabled state, but not to communicate the links as being "disabled". ... Another reason to use the `aria-disabled` attribute over the HTML `disabled` attribute is if you have created custom controls which need to be marked as disabled, but are not using an element that allows for the `disabled` attribute. For instance, in the following snippet a ` ` was used to create a custom button which needs to be marked as disabled. However, the ` ` element does not expect, nor respect the `disabled` attribute - even if it were to be given a `role="button"` to change its exposed ARIA role. The `aria-disabled` attribute is required to disable such custom controls. ... ``` <div role="button" aria-disabled="true" tabindex="-1">Edit</div> ``` ... Similarly to needing to use JavaScript to ensure an element with `aria-disabled="true"` is not functional, the element will also need styling adjustments. In contrast to the HTML `disabled` attribute, where specifying it provides `:disabled` user-agent styles to be applied, adding `aria-disabled="true"` doesn&`#39`;t. The element can be styled with the attribute selector `[aria-disabled="true"]`. ... If you are purposefully using the `aria-disabled` attribute to…[truncated] <title><button> HTML button element - HTML | MDN</title> https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/button `autofocus` : This Boolean attribute specifies that the button should have input focus when the page loads. Only one element in a document can have this attribute. ... `disabled` : This Boolean attribute prevents the user from interacting with the button: it cannot be pressed or focused. ... ### ARIA state information ... To describe the state of a button the correct ARIA attribute to use is `aria-pressed` and not `aria-checked` or `aria-selected`. To find out more read the information about the ARIA button role. ... It is best not to override the default focus ring for elements that have focus. If the button styles are overridden, it is important to ensure that the focus state has enough contrast so that people experiencing low vision conditions can perceive it and people with cognitive differences will understand it. ... The `:focus-visible` pseudo-class can be used to apply styles to an element that has `:focus` only when the user agent&`#39`;s heuristics determine that the focus should be highlighted, such as when a ` ` receives keyboard focus. See :focus vs :focus-visible for more information. ... ### Clicking and focus ... Whether clicking on a ` ` or ` ` button types causes it to (by default) become focused varies by browser and OS. Most browsers do give focus to a button being clicked, but Safari does not, by design. ... | Content categories | Flow content, phrasing content, Interactive content, listed, labelable, and submittable form-associated element, palpable content. | | --- | --- | | Permitted content | Phrasing content but there must be no Interactive content. If the ` ` is the first child of a customizable select element, then it may also contain zero or one ` ` element. | | Tag omission | None, both the starting and ending tag are mandatory. | | Permitted parents | Any element that accepts phrasing content. | | Implicit ARIA role | `button` | | Permitted ARIA roles | `checkbox`, `combobox`, `link`, `menuitem`, `menuitemcheckbox`, `menuitemradio`, `option`, `radio`, `switch`, `tab` | | DOM interface | `HTMLButtonElement` | <title>HTML Standard</title> https://html.spec.whatwg.org/multipage/form-control-infrastructure.html ##### 4.10.19.5 Enabling and disabling form controls: the `disabled` attribute ... The `disabled` content attribute is a boolean attribute. ... A form control is disabled if any of the following are true: ... - the element is a `button`, `input`, `select`, `textarea`, or form-associated custom element, and the `disabled` attribute is specified on this element (regardless of its value); or - the element is a descendant of a `fieldset` element whose `disabled` attribute is specified, and the element is not a descendant of that `fieldset` element&`#39`;s first `legend` element child, if any. ... A form control that is disabled must prevent any `click` events that are queued on the user interaction task source from being dispatched on the element. ... Being disabled does not prevent all modifications to the form control. For example, the control&`#39`;s value or checkedness could be modified programmatically from JavaScript. Or, they could be indirectly modified by user action, e.g., if other non-disabled elements in the control&`#39`;s radio button group were modified. ... Constraint validation: If an element is disabled, it is barred from constraint validation. <title>ARIA in HTML</title> https://www.w3.org/TR/html-aria/ There are also situations where certain `aria-*` attributes are allowed for use on elements with specific `role` s, while the equivalent native attribute is currently not valid in HTML itself. For instance, HTML has no direct concept of a disabled hyperlink (`a href` element). Constructs such as ` ... ` are not valid, and will not be conveyed to assistive technologies. ARIA diverges from HTML in this regard and does allow for an `aria-disabled` attribute to be specified on an element with an explicit `role=link`. If an author were to specify an `aria-disabled=true` on an HTML hyperlink, user agents would not functionally treat the hyperlink any differently (it would still be clickable/operable), however it would be exposed to assistive technologies as being in the disabled state. Similarly, while native HTML `option` elements that are descendants of a `select` can only be set as being `selected`, elements with an explicit `option` role can not only allow the equivalent `aria-selected`, but also the `aria-checked` attribute, supporting widgets/constructs that go beyond the capabilities of a native `select` element. Unfortunately, in these situations where ARIA and HTML have feature parity, but diverge in allowances, it can create for a misalignment in support, if not also user experiences. In situations where ARIA allows a feature not supported by HTML, it will often be in the author&`#39`;s and ultimately the user&`#39`;s best interest to instead implement as a fully custom ARIA widget. In the following example, a hyperlink needs to be communicated as being in the disabled state. HTML does not allow for the use of the `disabled` attribute on a hyperlink, and using `aria-disabled=true` would communicate the hyperlink as being disabled to assistive technologies, but would not actually disable the element. The most effective way to both communicate and actually disable a hyperlink would be to remove the `href` from the `a` element, creating a placeholder. Then, ARIA can be applied to this placeholder link to communicate the element&`#39`;s intended role and state. 2 : Communicate a disabled link with ARIA ... ``` <a role=link aria-disabled=true>...</a> ... to avoid incorrect ... | `a` with `href` | `role=link` | Roles: `button`, `checkbox`, `menuitem`, `menuitemcheckbox`, `menuitemradio`, `option`, `radio`, `switch`, `tab` or `treeitem`.

DPub Roles: `doc-backlink`, `doc-biblioref`, `doc-glossref` or `doc-noteref` Global `aria-*` attributes and any `aria-*` attributes applicable to the allowed roles. It is NOT RECOMMENDED to use `aria-disabled="true"` on an `a` element with an `href` attribute.

Requirements for use of ARIA attributes in place of equivalent 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.

The user can neither edit nor focus on the control, nor its form control descendants. ## Try it ``` <form> <label for="name">Name:</label> <input id="name" name="name" type="text" /> <label for="emp">Employed:</label> <select id="emp" name="emp" disabled> <option>No</option> <option>Yes</option> </select> <label for="empDate">Employment Date:</label> <input id="empDate" name="empDate" type="date" disabled /> <label for="resume">Resume:</label> <input id="resume" name="resume" type="file" /> </form> ``` ``` label { display: block; margin-top: 1em; } *:disabled { background-color: dimgrey; color: linen; opacity: 1; } ``` ## Overview If the `disabled` attribute is specified on a form control, the element and its form control descendants do not participate in constraint validation. Often browsers gray out such controls and it won&`#39`;t receive any browsing events, like mouse clicks or focus-related ones. The `disabled` attribute is supported by ` `, ` `, ` `, ` `, ` `, ` ` and ` `. This Boolean disabled attribute indicates that the user cannot interact with the control or its descendant controls. If this attribute is not specified, the control inherits its setting from the containing element, for example `fieldset`; if there is no containing element with the `disabled` attribute set, and the control itself does not have the attribute, then the control is enabled. If declared on an ` `, the select is still interactive (unless otherwise disabled), but none of the items in the option group are selectable. Note: If a ` ` is disabled, the descendant form controls are all disabled, with the exception of form controls within the ` `. When a supporting element has the `disabled` attribute applied, the `:disabled` pseudo-class also applies to it. Conversely, elements that support the `disabled` attribute but don&`#39`;t have the attribute set match the `:enabled` pseudo-class. This Boolean attribute prevents the user from interacting with the button. If this attribute isn&`#39`;t set, the button can still be disabled from a containing element, for example ` `; if there is no containing element with the `disabled` attribute set, then the button is enabled. Firefox will, unlike other browsers, persist the dynamic disabled state of a ` ` across page loads. Use the `autocomplete` attribute to control this feature. ### Attribute interactions The difference between `disabled` and `readonly` is that read-only controls can still function and are still focusable, whereas disabled controls cannot receive focus and are not submitted with the form and generally do not function as controls until they are enabled. Because a disabled field cannot have its value changed, `required` does not have any effect on inputs with the `disabled` attribute also specified. Additionally, since the elements become immutable, most other attributes, such as `pattern`, have no effect, until the control is enabled. Note: The `required` attribute is not permitted on inputs with the `disabled` attribute specified. ### Usability Browsers display disabled form controls grayed as disabled form controls are immutable, won&`#39`;t receive focus or any browsing events, like mouse clicks or focus-related ones, and aren&`#39`;t submitted with the form. If present on a supporting elements, the `:disabled` pseudo class will match. If the attribute is not included, the `:enabled` pseudo class will match. If the element doesn&`#39`;t support the disabled attribute, the attribute will have no effect, including not leading to being matched by …[truncated] <title>ARIA in HTML</title> https://www.w3.org/TR/html-aria/ There are also situations where certain `aria-*` attributes are allowed for use on elements with specific `role` s, while the equivalent native attribute is currently not valid in HTML itself. For instance, HTML has no direct concept of a disabled hyperlink (`a href` element). Constructs such as ` ... ` are not valid, and will not be conveyed to assistive technologies. ARIA diverges from HTML in this regard and does allow for an `aria-disabled` attribute to be specified on an element with an explicit `role=link`. If an author were to specify an `aria-disabled=true` on an HTML hyperlink, user agents would not functionally treat the hyperlink any differently (it would still be clickable/operable), however it would be exposed to assistive technologies as being in the disabled state. Similarly, while native HTML `option` elements that are descendants of a `select` can only be set as being `selected`, elements with an explicit `option` role can not only allow the equivalent `aria-selected`, but also the `aria-checked` attribute, supporting widgets/constructs that go beyond the capabilities of a native `select` element. Unfortunately, in these situations where ARIA and HTML have feature parity, but diverge in allowances, it can create for a misalignment in support, if not also user experiences. In situations where ARIA allows a feature not supported by HTML, it will often be in the author&`#39`;s and ultimately the user&`#39`;s best interest to instead implement as a fully custom ARIA widget. In the following example, a hyperlink needs to be communicated as being in the disabled state. HTML does not allow for the use of the `disabled` attribute on a hyperlink, and using `aria-disabled=true` would communicate the hyperlink as being disabled to assistive technologies, but would not actually disable the element. The most effective way to both communicate and actually disable a hyperlink would be to remove the `href` from the `a` element, creating a placeholder. Then, ARIA can be applied to this placeholder link to communicate the element&`#39`;s intended role and state. 2 : Communicate a disabled link with ARIA ... ``` <a role=link aria-disabled=true>...</a> ``` ... | `a` with `href` | `role=link` | Roles: `button`, `checkbox`, `menuitem`, `menuitemcheckbox`, `menuitemradio`, `option`, `radio`, `switch`, `tab` or `treeitem`.

The `aria-disabled` attribute, when set to `true`, indicates that the element upon which it is set and all of its focusable descendants are meant to be in the disabled state. This declaration will inform people using assistive technologies, such as screen readers, that such elements are not meant to be editable or otherwise operable. ... Unlike HTML&`#39`;s `disabled` Boolean attribute, which will communicate a form control as semantically being disabled, change its styling to reflect its state and suppress all functionality along with disallowing the element&`#39`;s value from participating in form submission, the `aria-disabled="true"` only semantically exposes these elements as being disabled. Web developers must manually ensure such elements have their functionality suppressed when exposed to the disabled state. ... When needing to disable native HTML form controls, developers will need to specify the `disabled` attribute, as it provides all of the generally expected features of disabling a control by default. However, there can be instances where elements need to be exposed as disabled, but are still available for users to find when navigating via the Tab key. Doing so can improve their discoverability as they will not be removed from the focus order of the web page, as `aria-disabled` does not change the focusability of such elements, nor will the elements be dimmed by default browser styling, making them easier to read. Some examples of where this may be useful include: ... - The header button element associated with non-collapsible accordion panel, - A button which is important to keep in the page&`#39`;s focus order, but its action is presently unavailable - such as submitting a form, - Temporarily inactive items in a menu widget that would otherwise be skipped over via standard keyboard navigation. ... In each of these cases, one may want users to find these elements through standard keyboard navigation, though the functionality of that control is removed or "disabled". Developers will still need to use JavaScript to fully disable the functionality of the element while also changing the appearance of the element so sighted users know it is disabled. ... > [!NOTE] > The state of being disabled applies to the element with `aria-disabled="true"` and all of its focusable descendants. Take care when using this attribute on container elements. Particularly in the case where a container may have both form controls and links - where the intent may be to expose the form controls as being in the disabled state, but not to communicate the links as being "disabled". ... Another reason to use the `aria-disabled` attribute over the HTML `disabled` attribute is if you have created custom controls which need to be marked as disabled, but are not using an element that allows for the `disabled` attribute. For instance, in the following snippet a ` ` was used to create a custom button which needs to be marked as disabled. However, the ` ` element does not expect, nor respect the `disabled` attribute - even if it were to be given a `role="button"` to change its exposed ARIA role. The `aria-disabled` attribute is required to disable such custom controls. ... ```html <div role="button" aria-disabled="true" tabindex="-1">Edit</div> ``` ... Similarly to needing to use JavaScript to ensure an element with `aria-disabled="true"` is not functional, the element will also need styling adjustments. In contrast to the HTML `disabled` attribute, where specifying it provides `:disabled` user-agent styles to be applied, adding `aria-disabled="true"` doesn&`#39`;t. The element can be styled with the attribute selector `[aria-disabled="true"]`. ... If you are purposefully using the `aria-disabl…[truncated]

Document the focusable native-button exception.

aria-disabled="true" can be used without disabled on a native button that must remain keyboard-focusable. The current instruction to “rely solely” on disabled can discourage this pattern and remove the button from the focus order. The handler must also block activation when using aria-disabled.

Suggested fix
-**Learning:** Using `aria-disabled` alongside the native HTML `disabled` attribute on `<button>` elements is a redundant accessibility anti-pattern. The native `disabled` attribute inherently communicates the unavailable state and manages focus correctly, while `aria-disabled` is typically only needed for custom semantic elements (like `div` acting as a button) that cannot use the native attribute.
-**Action:** When managing disabled states for interactive elements (like buttons), rely solely on the native `disabled` attribute for state management. For async operations (e.g., loading or saving), combine it with `aria-busy="true"` to communicate active updates, but never apply `aria-disabled` simultaneously.
