postcss 8.4.19

PostCSS is a powerful tool designed to transform styles using JavaScript plugins. This tool helps optimize your CSS to match industry standards through a variety of actions such as linting CSS, supporting variables and mixins, transpiling future CSS syntax, inlining images, and more. Some of the most popular CSS tools, like Autoprefixer and StyleLint, are plugins of PostCSS. Trusted by industry leaders like Wikipedia, Twitter, Alibaba, and JetBrains, PostCSS helps ensure your CSS is of the highest standard.

To utilize PostCSS, you would install the package via NPM in your project directory, then use it as a library in your JavaScript code along with any required plugins. For instance, let's say we want to use the Autoprefixer plugin. Here's a simple example of how you might use it:

Firstly, install PostCSS and Autoprefixer:

npm install postcss autoprefixer

Then, use them in your JavaScript code:

var postcss = require('postcss');
var autoprefixer = require('autoprefixer');

var css = 'body { display: flex; }';

postcss([autoprefixer])
  .process(css)
  .then(function(result) {
    console.log(result.css);
});

The postcss.process method is used to transform the CSS with the plugins provided in the array.
