Who this book is for

The book is for frontend developers who are familiar with HTML5 and CSS3, but want to master PostCSS as part of simplifying their development workflow or remove the dependency on existing processors, such as SASS or Stylus. To get the most out of this book, you should have a good knowledge of HTML, CSS3, and JavaScript, and ideally, have some experience of using preprocessors such as SASS, Less, or Stylus.
