Considerations for developers
- Keep it simple – not all browsers correctly expose multiple labels that are linked to the same form element.
- Use labels for every input and make the
for=""andid=""values match. IDs must be unique on each page, only one label can be associated to each unique form element. Make required fields obvious by using an indicator – asterisk, description text, etc. - Fields with error validation should have
aria-describedbyto insure that the associated field level error message is read by assistive technology. If the error message has anid="my-error-message", then the input should havearia-describedby="my-error-message".

Considerations for designers
- Focus must be visible.
- Don’t hide the input label on focus.
