The book is divided into three sections: Letter, Text, and Grid. But this structure is very conditional – the author constantly jumps from topic to topic – just talked about font licenses, but here we are talking about HTML title tags, or "branding". The book will be very useful for the overall development of design thinking in its broadest sense but is unlikely to teach you the basics. We recommend you to buy the online version to understand would it be interesting for you or not. Good luck in studying!
