There are many technical errors and typos in the book. The author doesn't mention checking your HTML for syntax problems with an HTML checker/validator, a very important thing to do when learning HTML and when creating web sites. If the HTML in the book was checked, the book would have had fewer problems. However, there are some otherwise good tips and information in the book.
