Web A11y Forms

Form Rules

For label and validation examples, see EXAMPLES.md.

1. Every field needs a persistent programmatic label.
2. Placeholder text must not be the only label or instruction.
3. Use native inputs and controls unless a custom widget is truly required.
4. Group related controls with fieldset and legend when the group label matters.
5. Associate help, constraints, and errors with the relevant control.
6. Preserve user input and focus context after validation failures.
