Lesson support

What to notice while you play.

Objective

Complete a project-shaped media fallback copy build while preserving each passing edit.

Hint

Start with the Current task. Open index.html, use Show exact edit when needed, Run, then follow the highlighted next task.

Why it matters

Links and media becomes durable when every syntax choice is tied to a visible project outcome and a specific piece of evidence.

Common mistakes

Editing the wrong file instead of index.html.
Replacing earlier passing work instead of preserving it for the next step.
Pressing Check before every task has passed Run.
Expecting learner HTML, CSS, or JavaScript to execute; the preview uses reviewed scene states only.
