What is the role of placeholder text in forms?

Placeholder text serves a significant purpose in forms by offering guidance on the expected input for a specific field. It typically appears in a light gray color within the input box and disappears once the user begins typing. This helps users understand what type of information is required in that particular field, such as an email address, phone number, or name. By clarifying expectations for user input, placeholder text enhances usability and reduces errors in form submissions.

While examples of completed forms or indicating required fields are essential aspects of good form design, placeholder text specifically aims to guide the user about the anticipated format and content. Additionally, aesthetic appeal is not the primary function of placeholder text; its main objective is to improve user experience and facilitate correct data entry.
