The third exercise of the book, Chapter 2, page 32, seems to be a strange formatting example. The format does not concern the normal browser page, but the source view.

I'd like to know from the author whether my observation is right.

If yes, why doesn't it say so in the text and what's the use of formatting text to be viewed in source view?

If no, what am I doing wrong? (Nota bene: I checked by copying the code from the book from page 296-297.)
