Help text is a brief explanation or instruction provided alongside a user interface element, such as a form field or button. Its purpose is to guide users by clarifying what information is needed or how to use a feature effectively. This can enhance user experience by reducing confusion and errors. Typically, help text appears in smaller font or a different color to distinguish it from the main content. It can include examples, tips, or links to more detailed resources, making it easier for users to understand how to interact with the system or complete a task successfully.
