Questions

Form Label Checker FAQ

What makes a form label accessible?

A visible label should usually use a for value that exactly matches its control's unique id, or wrap the control directly.

Can a placeholder replace a label?

No. Placeholder text disappears during entry and should be treated as an optional hint, not the field's persistent label.

When should fieldset and legend be used?

Use them to communicate the shared purpose of related controls, especially radio-button and checkbox groups.

Does this checker validate dynamic errors?

No. It checks static references only. Test validation messages, announcements, and focus behavior in the running form.

Apply the result

From finding to verified fix

Interpret the finding

Treat every missing or broken association as a barrier to understanding the field, then confirm the running form's instructions and errors.

Common causes to inspect

  • Placeholder text used instead of a persistent label
  • A label for value that does not match a unique control ID
  • Related choices presented without a programmatic group name

Practical next steps

  1. Give every control a visible, associated label
  2. Group related choices with fieldset and legend where appropriate
  3. Submit errors and test announcements and focus in the running form

What this check cannot prove

Static markup cannot verify dynamic validation, screen-reader announcements, focus movement, autocomplete behavior, or the complete submission flow.
