Labels tell users what information belongs in a given form field and are usually positioned outside the form field. Placeholder text, located inside a form field, is an additional hint, description, or example of the information required for a particular field.
something that marks or temporarily fills a place (often used attributively): I couldn’t find my bookmark, so I put a coaster in my book as a placeholder.
