The feeling of two books on CSS

Two books recommended on the home page of www.w3cn.org, CSS layout recording and website reconstruction. I first borrowed the former, and in its preface I saw the latter's respect, so I borrowed the latter. This is really rare for me after reading the first book, and I have never been patient with it for a long time. But after reading this book (at least basically reading it), my opinion on this book is that a very good book is very suitable for beginners like me. Although there are some small mistakes in the book, I can feel that the author has spent a lot of time thinking. Content arrangement, examples of selection, including a lot of practical little experience and skills, for things like CSS that are subject to great uncertainty due to the influence of standards and browsers, sharing the experience of a master is particularly important. Of course, the book does not solve this problem, but it has aroused my great interest. I have tried to implement some of my ideas over the past two days. So I can't help but give a thumbs up and I am very grateful for the selfless dedication of the author.
As for the second book, it may be that I am not enough, or that foreigners have different ways of thinking. After half a day, I did not understand what the author was talking about.
