Expectation: remove functionality of interactive content for assistive technologies (navigation and operation)

Rationale:

The inert attribute will prevent all click events for mouse users and hide content from assistive technologies, so all functionality should be removed for assistive technologies. This includes removing the inert content from the tab order, and preventing any interactions with inert content.

Strength of this expectation for different types of assistive technologies:

  • Screen Readers: MUST
  • Voice Control: MUST

Examples:

  • For keyboard: inert content will be removed from the tab order and it is not possible to trigger any functionality.
  • For screen readers: inert content will be removed from the tab order and it is not possible to trigger any functionality.
  • For voice control: it is not possible to trigger any inert functionality.

Expectation: hide static content from assistive technologies

Rationale:

Per the HTML specification, the inert attribute is expected to hide all contained content from assistive technologies.

Strength of this expectation for different types of assistive technologies:

  • Screen Readers: MUST
  • Voice Control: NA

Examples:

  • It is not possible to read anything contained within an element that has the inert attribute.
