I've been involved with the Head First series as a reviewer from the beginning and, as such, my review might be biased, but I will regret not telling you how good this book is.
The Internet is fast becoming a means of sharing one's life with friends, colleagues and anybody out there who is prepared to listen. Some start by telling their story using a blog; the more adventurous create their own web sites, and it is that category of person that this book is aimed at. Don't make the mistake of thinking that this book, and the whole series, seems too upbeat and too young for you. This book is for all ages, The Head First series is designed to make learning fun, and though it was originally aimed at the younger generation, I personally think that old age pensioners will be able to learn HMTL the correct way just as easily as their grand children if they use this book - and you will be sooo cool if you have this book on your shelf when they, the grand kids, visit again next time.
The emphasis in this book is on creating web pages the correct way, to make pages that will work correctly in any browser. If you work through Elisabeth and Eric's book, you will end up with a web site that can withstand anything the W3C's Markup Validation Service can throw at it. And when your web pages pass the validation, you can put the W3C's cool "passed validation" logo on your site. A sign of recognition that you know what you are doing.
This book does not require you to have prior HTML knowledge; it takes you by the hand and teaches you everything you need from scratch. But don't be fooled, I was the review manager for this book and even some of the reviewers with years of HTML knowledge under their belt learnt new things from it. Sure, it isn't a complete HTML reference book, and it does not intend being one, but it lays the foundations for a solid start to becoming a true HTML/CSS expert.
I think this book should become the standard text book in HTML/CSS courses in schools, colleges and even professional training centers.
I highly recommend it to all. It will make the perfect Christmas gift for your family, all ages !!!, friends and even colleagues who are thinking about or are doing something with a web site of their own.
Have fun.
Like I said, I might be biased, but I am sure an independent reviewer will confirm what I said.
