What are radio buttons on a webpage used for?

Radio buttons on a webpage are specifically designed to allow users to select one option among multiple choices. This interface element restricts selection to a single option from a group, ensuring that when one radio button is selected, any previously selected button in the same group is automatically deselected. This functionality is particularly useful in scenarios where only one response is applicable, such as choosing a payment method or selecting a preference from a list.

The design of radio buttons emphasizes exclusivity in selection, making them distinct from checkboxes, which enable users to select multiple options simultaneously. Given this exclusivity, users understand that they cannot select more than one radio button at a time, thereby simplifying decision-making in forms and surveys. This adherence to user-friendly guidelines in design aids in preventing errors and confusion during data entry.

Other options such as selecting multiple options or displaying images do not align with the primary purpose of radio buttons, as radio buttons are not intended for those functions. Likewise, while navigation may involve clicking on various elements, it does not directly pertain to the specific use and function of radio buttons in a selection context.
