PostCSS & Autoprefixer

PostCSS is a JavaScript ecosystem for transforming CSS.

• Autoprefixer adds missing vendor prefixes (-webkit-, -moz-).
• postcss-preset-env lets you use future CSS syntax now.

Example: postcss.config.js

module.exports = {
  plugins: [
    require('autoprefixer'),
    require('postcss-preset-env')({ stage: 1 })
  ]
};
