What are the three key pieces of accessibility information ARIA provides for assistive technologies?

The selection of name, role, and value as the three key pieces of accessibility information provided by ARIA for assistive technologies is accurate because these elements are fundamental to how assistive technologies interpret and convey information about web content to users with disabilities.

The "name" is crucial as it provides the accessible name of an element, allowing screen readers or other assistive devices to announce what the element is. This is vital for users to understand which element they are interacting with.

The "role" describes what type of UI element it is (e.g., button, checkbox, landmark). This information helps users navigate and interact with the content appropriately, as the role conveys the behavior and expected interactions associated with the element.

The "value" is important for dynamic elements, such as form inputs. It conveys the current state of the element, helping users understand if a form field is filled, checked, or has some selectable options.

These three pieces of information enhance the accessibility of web content by ensuring that users receive contextually relevant information regarding what they are interacting with, ultimately leading to a more inclusive web experience.
