WCAG 3.3.3: Error Suggestion
WCAG 3.3.3 requires that when an input error is automatically detected, the system must provide a text description suggesting how the user can correct the mistake — unless doing so would jeopardize security or purpose. This criterion is essential for users with cognitive disabilities, screen reader users, and anyone who struggles to understand vague or missing error guidance.
