How to add dynamic background in NextJS with Tailwind?

Question

I have an poster image, that I will use it to make it as a background image. I fetch it from MovieDb. I put it inside className like so className={ bg-[url('${path}')] h-screen bg-cover bg-center text-white border-b-8 border-b-solid border-b-slate-400 } .But it throw error

./styles/globals.css:5:0
Module not found: Can't resolve './${path}'

Import trace for requested module:
./styles/globals.css
./pages/_app.js

https://nextjs.org/docs/messages/module-not-found

I want to add my browse.tsx file also

import { GetStaticProps } from "next";
import React from "react";
import { getData } from "./api/randomMovie";
import { getServerSideProps } from "./gr-en";

export default function Browse({ movies }) {
  console.log(movies);
  const { poster_path } = movies;
  const path =
    "https://www.themoviedb.org/t/p/w1280_and_h720_multi_faces/rYFAvSPlQUCebayLcxyK79yvtvV.jpg";
  console.log(path);
  return (
    <div
      className={`bg-[url('${path}')] h-screen bg-cover  bg-center text-white border-b-8 border-b-solid border-b-slate-400`}
    >
      <nav className="grid grid-cols-2 py-2 text-white  bg-black/60">

          <li className="mx-2">My List</li>
        </ul>
      </nav>
    </div>
  );
}

export const getStaticProps: GetStaticProps = async (context) => {
  const movies = await getData();

  console.log(movies);
  return {
    props: { movies },
  };
};

So what is the way to use dynamic path inside className with template literals?

Answer 1

You can't use string concatenation to create CSS class names in tailwind - see this answer .

To overcome this intentional design by the tailwind team and since your styles are dynamic per movie - you should place your background-image style inline.

 <div styles={{backgroundImage:`url(${path})`}} classNames="....">
