Mastering PostCSS for Web Design

Overview of this book

PostCSS is a tool that has quickly emerged as the future of existing preprocessors such as SASS and Less, mainly because of its power, speed, and ease of use. This comprehensive guide offers in-depth guidance on incorporating cutting-edge styles into your web page and at the same time maintaining the performance and maintainability of your code. 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.

  2. At the command prompt, enter the following command, then press Enter:
    npm install --save-dev postcss-css-variables

At this point, Node will have also added an entry to the package.json file for the new plugin. Perfect—we can now put it to good use and switch to using the plugin in place of using SASS. Let's take a look at how to achieve this, as part of the upcoming exercise...
