How to implement:

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

Code:

import styles from './AnimatedBackground.module.css';

export default function Background() {
  return (
    <div className="flex flex-col items-center h-screen w-full">
      <div className={styles.container}>
        <div className={styles.lines}>
          <div className={styles.line}></div>
          <div className={styles.line}></div>
          <div className={styles.line}></div>
          <div className={styles.line}></div>
          <div className={styles.line}></div>
        </div>

       {yout page/ component}
      </div>
    </div>
  );
}

Code: AnimatedBackground.module.css

.container {
  display: flex;
  width: 100%;
  height: 100%;
  background: radial-gradient(ellipse at bottom, #310d29 0%, #0c0d13 100%);
  color: #000;
  position: relative;
  font-family: sans-serif;
  overflow: hidden;
  align-items: center;
  flex-direction: column;
}

.lines {

  height: 100%;
  margin: auto;
  width: 90vw;
}

.line {
  position: absolute;
  width: 1px;
  height: 100%;
  top: 0;
  left: 50%;
  background: rgba(255, 255, 255, 0.1);
  overflow: hidden;
}

.line::after {
  content: '';
  display: block;
  position: absolute;
  height: 15vh;
  width: 100%;
  top: -50%;
  left: 0;
  background: linear-gradient(to bottom, rgba(255, 255, 255, 0) 0%, #ffffff 75%, #ffffff 100%);
  animation: drop 7s 0s infinite;
  animation-fill-mode: forwards;
  animation-timing-function: cubic-bezier(0.4, 0.26, 0, 0.97);
}

/* 1 line */

.line:nth-child(1) {
  margin-left: -25%;
}

.line:nth-child(1)::after {
  animation-delay: 2s;
}

/* 3 line */

.line:nth-child(3) {
  margin-left: 25%;
}

.line:nth-child(3)::after {
  animation-delay: 2.5s;
}

/* 4 line */

.line:nth-child(4) {
  margin-left: 50%;
}

.line:nth-child(4)::after {
  animation-delay: 1s;
}

/* 5 line */

.line:nth-child(5) {
  margin-left: -50%;
}

.line:nth-child(5)::after {
  animation-delay: 1s;
}

@keyframes drop {
  0% {
    top: -50%;
  }
  100% {
    top: 110%;
  }
}
