The “3D Flip Confirmation Button” is an interactive UI effect where a button flips in 3D space to reveal a confirmation prompt before performing action. On click, button rotates to display options like “Yes” and “No,” allowing users to confirm or cancel choice. This visually engaging effect adds an extra layer of user assurance for sensitive actions, such as deleting content.
