Which HTML5 attribute provides a hint identifying the expected input in a form field?

• A. The placeholder attribute
• B. The autocomplete attribute
• C. The pattern attribute
• D. The title attribute

Answer: (A)

Providing a hint about the expected input is done with the placeholder attribute. When the input field is empty, the placeholder text appears inside it (for example, [e-mail] in an email field) to show the user what kind of data to enter. This hint disappears as soon as the user starts typing and it isn’t included in the submitted data, making it a lightweight guide rather than part of the actual value. The other attributes serve different purposes: autocomplete suggests previously entered values, not a current-field hint; pattern enforces a required format using a regular expression; and the title provides a tooltip-style message rather than in-field guidance. For accessibility, pair a placeholder with a proper label so users relying on screen readers still understand the field’s purpose.
