Focus placed

supplemental

Normative Text

When keyboard focus moves from one context to another within a page/view, whether automatically or by user request, the keyboard focus is preserved so that, when the user returns to the previous context, the keyboard focus is restored to its previous location unless that location no longer exists.

Method: When removing interactive elements such as filters, dialogs, or popups that currently contain focus, actively place the focus back on the element that led to that element, the previous element within the focus order, or another meaningful location.

Best Practice: Conduct usability testing with screen reader users to evaluate the focus movement.

Tests

This section is non-normative.

Procedure

For each situation where elements that have or contain keyboard focus are removed:

  1. Check that the keyboard focus moves to its previous location, or, if that no longer exists, to another meaningful location.

Expected results

  • #1 is true for each situation.

Tests

This content needs to be written.

Key Terms

actively available

available for the user to perceive and use

conformance scope

A set of Views and/or Pages selected to be part of a conformance claim. Where a View or Page is part of a Process, all the Views or Pages in the process must be included.

How a person or organization selects the set is not defined in WCAG3. There maybe informative guidance on selecting a suitable set in future (similar to WCAG-EM), but regional laws or regulations may provide a methodology.

content

information, sensory experience and interactions conveyed

keyboard focus

point in the content where any keyboard actions would take effect

page

non-embedded resource obtained from a single URI using HTTP plus any other resources that are used in the rendering or intended to be rendered together

Where a URI is available and represents a unique set of content, that would be the preferred conformance unit.

platform

software, or collection of layers of software, that lies below the subject software and provides services to the subject software and that allows the subject software to be isolated from the hardware, drivers, and other software below

Platform software both makes it easier for subject software to run on different hardware, and provides the subject software with many services (e.g. functions, utilities, libraries) that make the subject software easier to write, keep updated, and work more uniformly with other subject software.

A particular software component might play the role of a platform in some situations and a client in others. For example a browser is a platform for the content of the page but it also relies on the operating system below it.

The platform is the context in which the conformance scope exists.

process

series of views or pages associated with user actions, where actions required to complete an activity are performed, often in a certain order, regardless of the technologies used or whether it spans different sites or domains

view

content that is actively available in a viewport including that which can be scrolled or panned to, and any additional content that is included by expansion while leaving the rest of the content in the viewport actively available

A modal dialog box would constitute a new view because the other content in the viewport is no longer actively available.

viewport

object in which the platform presents content

The author has no control of the viewport and almost always has no idea what is presented in a viewport (e.g. what is on screen) because it is provided by the platform. On browsers the hardware platform is isolated from the content.

Content can be presented through one or more viewports. Viewports include windows, frames, loudspeakers, and virtual magnifying glasses. A viewport may contain another viewport. For example, nested frames. Interface components created by the user agent such as prompts, menus, and alerts are not viewports.
