All, I have submitted in your form what I believe are minor errors. In Appendix A for Chapter 2, the book has the title as
<title>Example Cafe - menu<title>
for all three pages (menu.html, contact.html, and opening.html).
This error can be found on page 449. I believe the correct answer should be
<title>Example Cafe - Opening<title>
for opening.html on line 5 and
<title>Example Cafe - Contact<title>
for contact.html on line 5.
