A checkbox is a graphical user interface element that allows users to make a binary choice, typically represented as a small square box. When the box is checked, it indicates a selection or agreement, while an unchecked box signifies the opposite. Checkboxes are commonly used in forms, surveys, and applications to gather user preferences or options. Checkboxes can be found in various digital platforms, including websites and software applications. They are often used in conjunction with other input elements, such as radio buttons and text fields, to create interactive and user-friendly experiences. Users can select multiple checkboxes at once, making them ideal for situations where multiple options are applicable.
