The book will show how you can take advantage of PostCSS to simplify the entire process of stylesheet authoring. It covers various techniques to add dynamic and modern styling features to your web pages. As the book progresses, you will learn how to make CSS code more maintainable by taking advantage of the modular architecture of PostCSS. By the end of this book, you would have mastered the art of adding modern CSS effects to web pages by authoring high performing, maintainable stylesheets.

Introducing nesting

The concept of nesting is nothing new when using processors such as Less CSS or SASS; it's a useful technique to help reduce the amount of code we need to write, and to organize code in a more human-readable format.

The flipside of the coin is that it is frequently abused—when using processors for the first time, many developers fall into the trap of thinking that everything should be nested. One can get away with it if the code is very simple; it is more likely to result in fragile code that is difficult to read and easily broken with simple changes to one or more styles in the code.

If nesting is done correctly, then it can be very effective; it helps avoid the need to repeat parent selectors, and allows us to group together rules that apply to the same selector, together. To see what is meant by this, take a look at this simple example for SASS:

#main p {
  color: #00ff00;
  width: 97%;

  .redbox {
    background-color: #ff0000;
    color: #000000;
  }...
