PostCSS - First Look

PostCSS is a CSS post-processor engine that allows you to transform regular CSS through JavaScript plugins. Like LESS, Sass, and Stylus, these plugins allow you to use CSS in new and exciting ways like automatically prefixing your CSS for older browsers; adding variables, conditionals, or nesting; and even transpiling next-generation CSS so that it works in older browsers today. PostCSS can be 3–30 times faster than other pre-processors and offers a modular approach, so you can install just the plugins you want to use.
