Cascading Style Sheets, better known as CSS, is one of the foundational technologies that drives the Web. CSS lets you precisely specify the visual design of a web page or web app, from the structural layout of elements on the page to their individual look and feel. If you are like most web developers, you know just enough CSS to get by. You can do basic styling and layout, but you often run into roadblocks. If you know CSS, but you don't really know CSS, this is the book for you.

CSS in Depth takes web developers from beginner to advanced CSS users, getting rid of their blind spots along the way. In this book, you'll revisit concepts you are likely familiar with but have not completely mastered. You'll also encounter advanced subjects, like transitions and animations, as well as brand new ideas, like flexbox and grid layout. You'll start by going deep into the essentials of CSS while you get practical advice to help you maintain control over your styles. Next, you'll dive deep into layout topics and learn to tackle common pitfalls. Then you'll focus on organizing your code and dealing with CSS at scale. The last part of this book explains more advanced techniques the average developer probably hasn't worked with, like transitions, animations, and transformations, as well as practical design skills: how to choose colors and typography so your page or app is pleasing to look at and use.
