Paper parcel rule labYear 10 Subjects · T1 W3–4 · Interactive activity

This offline practice tool uses invented label states only. It sends and stores no input. READY needs readable AND reviewed. An unknown value asks for a data check; it is not silently changed to NO. This is not a real parcel, booking, borrowing or security system.

Predict, then test

Write or say your expected result first. Choose the two fictional input states and run both rules.

No case has been run yet.

Content means the words shown to a reader, such as “Paper parcel rule lab”. Structure uses markup, such as <h1>Paper parcel rule lab</h1>, to identify that text as the top heading. Presentation uses CSS, such as h1 { color: #173b50; }, to change appearance without changing the heading's words or meaning. The page still works in plain text through the full text route.
