Mr. Gasston has a dry wit, which really is engaging and fun to read. He’s also well versed on the subject and has a wonderful additional reading section at the end of each chapter which links you to not only his source materials, but to materials designed to push you further down the pathway to better programming. The book is aimed to the intermediate level developer who, like me, write good solid web pages, but knows there are a lot of things I can do to both help myself and improve my work as I go along. My favourite section had to be Chapter 3 with the device responsive CSS ideas. This really gave me a lot of ideas as to what to do with a portfolio site I work on. I also was very interested in the information about device APIs from Chapter 6.
That criticism aside, I heartily recommend this book and following up with it on the website he’s created for it. It will make your web work stronger!
