CSS has grown from a language for formatting documents into a robust language for designing web applications. Its simplicity is deceptive, however. It belies the complexity of the box model, stacking contexts, specificity, and the cascade. It’s tough to develop interfaces that work across a variety of screen sizes and with an assortment of input mechanisms. CSS mastery lies in understanding these concepts and how to mitigate them, as well as understanding and using new tools such as linters, optimizers, and preprocessors.
This book will show you how to write better, more efficient CSS, and to take advantage of the plethora of the new cutting-edge CSS features available to the front-end developer. You’ll also learn to master tools that will improve your workflow.
