CHAPTER 25 VISUAL LABS — boards 25a and 25b

These are original fictional teaching examples. Work locally.
Read the named boards first. Predict before running, and explain any
difference before changing a second thing.

HOW TO REPRODUCE
1. Open review.html in a browser. Read its tab, heading and paragraph.
2. Open the same file in your text editor. Match each visible item to
   its title, h1 or p element (board 25a).
3. Click the link. The contact.html page should open. Its return link
   should reopen review.html (board 25b).

CHANGE / PREDICT / CHECK
Change only the title text to Harbour Office review. Before refreshing,
predict which words change. Save and refresh: only the tab title changes.
Now change only href="contact.html" to href="contacts.html". Predict the
requested name, save and reload review.html, then click. It fails because
this folder contains no contacts.html. Restore contact.html and retest.
Changing the clickable wording alone does not change the destination.

EXPECTED ORIGINAL RESULT
Tab: Office supply review | Harbour Office
Heading: Make office ordering easier
Paragraph: Review your supplies with Harbour Office.
Link destination: the contact.html file in this folder.
No server, account or installation is needed.
