Hi, I want to ask you guys if you could recommend me a good book for web programming. By the way, I'm a intermediate web programmer, fairly knowledgeable in HTMl, XHTMl, and CSS and I would like a book that would teach more in usability and flexibility of the website, and other kinds of books that would give me broad knowledge in web programming.
Also, If your gonna recommend a book pls tell me why that books is good, Thanks:)
