window
A browser or application window.
Abstract roles are the foundation upon which all other WAI-ARIA roles are built. Content authors MUST NOT use abstract roles because they are not implemented in the API binding.
Description
A browser or application window.
Elements with this role have a window-like behavior in a graphical user interface (GUI) context, regardless of whether they are implemented as a native window in the operating system, or merely as a section of the document styled to look like a window.
Note: In the description of this role, the term "application" does not refer to the application role, which specifies specific assistive technology behaviors.
Note: window is an abstract role. Authors should not use this role in content.
