An "Input Box" is a graphical user interface element that allows users to enter data or information. It typically appears as a rectangular field where users can type text, numbers, or other types of input. Input boxes are commonly used in software applications, websites, and forms to collect user responses or commands. Input boxes can be customized to accept specific types of data, such as email addresses, passwords, or search queries. They often include features like placeholder text, which provides a hint about what to enter, and validation to ensure the input meets certain criteria before submission.
