The Hip Pocket Guide is a great portable reference for HTML 4. I wouldn't recommend it as a beginner's first or only book, but for someone who knows the basics, it is extremely helpful. Whenever I need a reminder about what attributes I can use with a particular tag, this is the book I refer to.It is especially great for the web designer who must travel throughout the day. Whether I'm working on my pages at home, or teaching HTML at work (USF - Tampa), I've got this guide with me.
