Before reading this book, I had already made several sites. Since I read this book, I decided to rewrite them all even if it is a huge job. Why? Because at the reading of this book, one realizes that making sites with HTML editors do not give work "clean" by not distinguishing enough content (XHTML) and its formatting (CSS). This is important for the updates of the sites for their SEO, for the clarity of their writing ... I say bravo to the author for his pedagogy. At the end of each chapter, it seems not to have learned much. Yet at the end of this book, we are pleased to have progressed slowly but surely. One is able to build a site in the rules of art. Finally, I can only recommend reading this book to any novice webmaster or believer experienced, as was my case. However a small complaint: the author often criticizes Internet Explorer. Even though I am for the development of free software like Firefox, my favorite arguments in support, IE7. Apart from the dispute, thank you Mr. Nebra.
