A local two-step fictional workshop-registration form with labeled fields, preserved back navigation, error summary and a review-before-submit screen; no data is sent.

Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.

What to include

  • Create a step map and verify that Next, Review, and local completion have distinct behavior.
  • Produce an inspected label/group map with working for/id associations.
  • Record missing, malformed, endpoint, and repaired input behavior with actionable error messages.
  • Build a Back-navigation matrix proving that edits change the intended value and preserve other fields.
  • Produce a literal-text review that rejects an invalid complete request and reflects changed valid values.
  • Deliver source plus separate rule-test and rendered-journey evidence, with honest unverified checks.

Review and revise

Use these criteria to check your work and choose what to improve.

  • The implementation or declared simulation follows the supplied contract and retains inspectable original inputs.
  • Normal, boundary and rejected cases are recorded with expected versus observed results.
  • The changed case has a correct explanation and does not rely on hidden state.
  • The project includes source, outputs, instructions and honest tool, privacy and verification limits.

The idea in everyday life

The workshop choice contains nickname and session; the second group contains seats.

The idea

A visible label names an individual control; a fieldset legend names a related group. Placeholder text is not a persistent label.

Follow along

Give controls explicit labels and groups — original worked practice

A visible label names an individual control; a fieldset legend names a related group. Placeholder text is not a persistent label.

The workshop choice contains nickname and session; the second group contains seats.

  1. 1. Step 1

    In workshop.html locate label for="nickname" and input id="nickname". Keep the two values identical.

    You should see: Activating the nickname label focuses its input.

    A visible label names an individual control; a fieldset legend names a related group. Placeholder text is not a persistent label.

  2. 2. Step 2

    Locate the session label and select id; activate the label, then use the keyboard to choose Morning.

    You should see: The select has a persistent visible name.

    A visible label names an individual control; a fieldset legend names a related group. Placeholder text is not a persistent label.

  3. 3. Step 3

    Read each fieldset legend: Workshop choice and Seat request. Keep instructions beside the control.

    You should see: The two steps have distinct group names.

    A visible label names an individual control; a fieldset legend names a related group. Placeholder text is not a persistent label.

  4. 4. Step 4

    Change the visible nickname label to Practice name while retaining for="nickname"; reload and test focus.

    You should see: A label/group checklist including the changed label and focus result.

    A visible label names an individual control; a fieldset legend names a related group. Placeholder text is not a persistent label.

Now change one thing

The input id changes to participant but its label still says for="nickname". What must for become?

Your work

What to finish

Produce an inspected label/group map with working for/id associations.

Common mistake

Watch for this

Replacing a persistent label with text that disappears after typing.

How can I tell I understand it?

Demonstrate the rule: A visible label names an individual control; a fieldset legend names a related group. Placeholder text is not a persistent label. Use the supplied variant to distinguish a changed result from a broken implementation.
