    require('autoprefixer')
  ]
}

Step 4: Create the responsive breakpoints and the classes you need and pass it to the plugin argument.

+const breakpoints = [
+  { prefix: 'sm\\:', mediaQuery: '(max-width: 480px)' },
+  { prefix: 'md\\:', mediaQuery: '(max-width: 640px)' },
+  { prefix: 'lg\\:', mediaQuery: '(max-width: 980px)' },
+  { prefix: 'xl\\:', mediaQuery: '(max-width: 1264px)' },
+];

+const classes = [
+ '.foo',
+ /\.bar-*/
+];

module.exports = {
  plugins: [
+   require('postcss-responsive-variations')({breakpoints, classes}),
    require('autoprefixer')
  ]
}
