Cant get it work

I want to develop a npm package and use for it rollup and there I am using custom styling with tailwind css but I also bootstrap and coreui styling.
However the styling is not avaiable. I created a minimal example to demonstrate this issue.

```
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]
```
