I bought this book for a long time and read it intermittently. I spent some time reading it systematically. Strictly speaking, I read this book system for the second time. It was because many knowledge points could not be understood, so there was no system. Although this time there are a lot of knowledge points not to understand. But every time you read this book, there is always a difference, because every time you improve, I think this book will always be with me.
This book is very popular. It is not only a tutorial, but also a manual. You can refer to the book if you encounter any problems in your future work.
Attribute conventions in the preface allow me to better understand CSS standards.
Structure and overlap I know the particularity and importance. Understand cascade rules.
Understand the attribute writing standards in CSS, the attributes that can be combined for writing, and the order of writing.
Know which attributes are inherited.
Understand the box model and various selectors of elements.
Measure the test taker's understanding about the CSS style sheets of common user proxies.
And so on ....
