Placeholder Text

Definition: Placeholder text is brief, temporary text displayed inside an empty form field to suggest the expected input, format, or type of information. It disappears when a user begins typing and may reappear if the field is cleared. Common uses include showing a formatting pattern, such as a date structure, or offering a short prompt, such as an example of a search term. Placeholder text is separate from a field label, which identifies the field and should remain visible or otherwise available while the user completes the form.

Used carefully, placeholder text can reduce uncertainty and help users enter information correctly, particularly when the required format is not obvious. It should not contain essential instructions, because it vanishes during entry and can be difficult to read due to low contrast. Relying on it instead of a persistent label can also make completed forms harder to review and create accessibility problems. Keep placeholder copy short, use sufficient contrast, and pair it with a clear label and helpful error messages when needed.

Analogy: Think of placeholder text as a sample answer lightly written on a blank worksheet. It shows what kind of response belongs in the space, but it is not the question or the student’s final answer. Similarly, a form field still needs a lasting label after the placeholder disappears.
