Frontend Engineering, Volume I: Pro HTML, explains the HyperText Markup Language that is behind most content on the modern World-Wide Web, including websites and the modern apps that are proliferating as fast as smart phones. It explains the professional's approach to creating HTML pages, which takes a bit more savvy (but no more work) than writing amateur HTML. This book is one half of the combined print/website "knowit" that will teach you what you need to know to create your own website, like the online sample. When you complete it you will be able to create your own web content and, if you choose, go on to CSS, the second language for aspiring frontend engineers.
