Defining views

Web page

A 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 with it by a user agent.

Web page in WCAG 2.2

Views

Views include all content visually and programmatically available without a substantive change. Conceptually, views correspond to the definition of a web page as used in WCAG 2, but are not restricted to content meeting that definition. For example, a view could be considered a “screen” in a mobile app or a layer of web content – such as a modal.

Views in WCAG 3

Non-web Context

A small number of success criteria are written to apply to “a set of web pages” or “multiple web pages” and depend upon all pages in the set to share some characteristic or behavior. Since the unit of conformance in WCAG 2 is a single web page, the task force agreed that the equivalent unit of conformance for non-web documents is a single document. It follows that an equivalent unit of evaluation for a “set of web pages” would be a “set of documents”. Since it isn't possible to unambiguously carve up non-web software into discrete pieces, a single “web page” was equated to a “software program” and a “set of web pages” was equated to a “set of software programs”.

Mobile Context

The Mobile Accessibility Task Force wants to define view in a mobile context, especially for mobile apps.

• Android has activities, fragments and views.
• iOS has view controllers, container views and views.

A screen can get pushed onto the stack (going forward),
and can be popped (going back).
