WCAG 3.0 is an active W3C Working Draft in development by the AGWG. Requirements, assertions, the conformance model and reporting tiers are still being developed and may change. The latest published draft is the 10 September 2026 Working Draft; this site follows the editors’ draft, which also includes exploratory provisions.
Receiving and then removing pointer hover or keyboard focus triggers additional content to become visible and then hidden, and the visual presentation of the additional content is controlled by the author and not by the user agent.
Notes in the draft
This applies to content that appears in addition to the triggering of the interactive element itself. Since hidden interactive elements that are made visible on keyboard focus (such as links used to skip to another part of a page/view) do not present additional content, they are not covered by this requirement.
Examples from the Draft
Worked examples the W3C editors wrote into the provision itself, not
examples invented here.
Additional content controlled by the user agent includes browser tooltips created through use of the HTML title attribute.
Custom tooltips, sub-menus, and other non-modal popups that display on hover and keyboard focus.
Content that appears on pointer hover or keyboard focus remains visible until the hover or keyboard focus trigger is removed, the user dismisses it, or its information is no longer valid.
