After closing exposed content, should focus return to the UI component that exposed it?
Question
After exposed content is closed, does focus need to move back to the UI component that exposed it?
Answer
Upon closing revealed content, focus should move back to the component which revealed the content (most often this is a button element). When exposed content is closed, for example a modal dialog, the input focus must move back to the component that exposed the modal dialog.
