This book does contain useful information, but you could probably learn just as easily by looking at teaching aids online. Also my teacher is very dissapointed in the book for it's lack of diferentiation between html and xhtml styles. It combines them quite often and makes it difficult for someone who is trying to learn new style code instead of depreciated code.Also the layout of the book is terrible. There are lines all over the page that do nothing but distract the reader. Apparently white space wasn't good enough for this author.
