It works correctly on tailwind, so the style will be given.

Example

tailwind.config.js

module.exports = {
  future: {
    // removeDeprecatedGapUtilities: true,
    // purgeLayersByDefault: true,
  },
  purge: ['./components/**/*.tsx', './pages/**/*.tsx'],
  theme: {
    colors: {
      old: {
        button: 'rgb(82, 165, 165)',
      },
    },
    extend:
