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 background() {
  return (
    <div className="relative flex flex-col h-screen bg-gradient-to-t from-emerald-950 to-neutral-950">
      <div className="absolute inset-0 flex items-center justify-center">
