This book is designed to be a quick way to learn HTML and HTML5. It should also be used as a reference for you to look back at for refreshers and information on tags that are commonly used. This is a great resource for students and professionals that need a quick reference or wish to learn the basics of HTML and HTML5 quickly. As a computer science professor, I've taught hundreds of students HTML. The reason I wrote this book is help teach others HTML and HTML5.
