Is an example inside the field enough?
Type a value into the field. The label “Email for our reply” should still be visible after the example disappears. Record the page and the exact field in the handover so the client can repeat the check.
How do I check the label connection?
Click the words beside the box. For a regular text field this should place the cursor in the associated control. In the markup, check that the label’s “for” value matches the field’s “id”.
What about a group of choices?
Read “Morning” and “Afternoon” on their own. A shared question tells you that you are picking an appointment time. Wrap the options in a fieldset and use a legend for that question. Give the client a completed test form to inspect.
