How to implement:

With tailwind installed in your project (tutorial), implement these tailwind classes in your parent div where it will reflect the background.

export default function BlackHole() {
  return (
    <section
      className="flex flex-col items-center h-screen"
      style={{
        backgroundImage: `
          radial-gradient(circle at top, #000 35%, #733000 45%, #000 75%)
        `
      }}
    >
  
      {your component or page}
    </section>
  );
}
