3.3.2 Labels or Instructions
레이블 또는 안내
Summary
Wherever input is required, labels or instructions must be provided. Placeholder text disappears once typing begins, so it cannot stand in for a label. Required-field markers and format hints — date patterns, password rules — fall under this criterion too.
Common failures
- Relying on a placeholder instead of a label, so the field's purpose vanishes once typing starts.
- Withholding password rules until after submission, then reporting them as an error.
