This book is an awesome read, for anyone who is learning or knows CSS. You can also use it as a reference after you're done reading it.
I loved the book! Clear and concise makes it an awesome book.
I like how the book is straight to the point. It makes it easier to find info that I'm looking for. In addition, I don't really like reading things that add unnecessary words that don't contribute to understanding the concepts. So no fluffs is a plus for me.
The book lives up to its name. There are a lot of diagrams and short descriptions that will aid in understanding CSS Concepts. This helps in visualizing how the CSS affects the appearance of an element in HTML. Moreover, by just glancing on the Diagrams, you can get an idea of how a property work. I also believed that learning CSS visually is beneficial since CSS is concerned with the appearance and/or style.
