I want to build a npm package with rollup but the styling is not available. I want to use style with tailwindcss, css or scss. I created a repo with demo code to demonstrate this issue. You can do the steps in README.md and then you will see that the styling is not applied Repo

This is my rollup.config.js

import babel from "@rollup/plugin-babel";
import image from "@rollup/plugin-image";
import json from "@rollup/plugin-json";
import commonjs from "rollup-plugin-commonjs";
import { nodeResolve } from "@rollup/plugin-node-resolve";
import replace from "@rollup/plugin-replace";
import sourcemaps from "rollup-plugin-sourcemaps";
import postcss from "rollup-plugin-postcss";

const input = "src/index.jsx";

var MODE = [
  {
    fomart: "es",
  },
];

var config = [];

MODE.map((m) => {
  var conf = {
    input: input,
    output: {
      dir: `dist`,
      format: m.fomart,
      sourcemap: true,
    },

    inlineDynamicImports: true,
    plugins: [
      replace({
        "process.env.NODE_ENV": JSON.stringify("development"),
      }),
      nodeResolve({
        extensions: [".js", ".jsx"],
      }),
      postcss({
        minimize: true,
        modules: true,

        extract: true,
      }),

      json(),
      image(),
      babel({
        exclude: "node_modules/**",
        plugins: ["@babel/transform-runtime"],
        babelHelpers: "runtime",
      }),
      commonjs({
        include: "node_modules/**",
      }),
      sourcemaps(),
    ],
  };
  config.push(conf);
});

export default [...config];
