No, not at all. The essentials of web design have ot changed, although new things have certainly been introduced.
Also I read in the book that NoteTab is another type of editor for web pages. I don't know if I should use the regular Notepad that came with my computer or NoteTab.
There are lots of code editors, many of them free, and it doesn't matter in the least which you use, as it's the code itself that matters. Which editor you use is as irrelevant as what color hammer you use to drive nails.
