W3C ARIA specification.
An ARIA property is a characteristic feature of a widget/control that can change over time but
more rare than the ARIA state and is often not changed as a result of user action.
The following groups of properties exist:
- Widget properties -- specific to common user interface elements found on GUI systems or
in rich Internet applications which receive user input and process user actions
- Live Region properties -- specific to live regions in rich Internet applications; may be
applied to any element; indicate that content changes may occur without the element having
focus, and provides assistive technologies with information on how to process those content
updates.
- Drag-and-drop states -- indicates information about draggable elements and their drop
targets
- Relationship properties -- indicates relationships or associations between elements which
cannot be readily determined from the document structure
