In this article, we are going to build a container that generates rain by using JS. And it is a colorful rain with random colors. You can play with colors however you want. So first, let's see what are we building.

Now let's look at the code, how we can make that work.

HTML

<div class="rain-container"></div>

CSS

* {
  margin: 0;
  padding: 0;
}

.rain-container {
  position: relative;
  background: #000;
  width: 100vw;
  height: 100vh;
  overflow: hidden;
}

i {
  position: absolute;
  height: 120px;
  border-radius: 0 0 999px 999px;
  animation: animate 5s linear infinite;
}

@keyframes animate {
  0% {
    transform: translateY(-120px);
  }
  100% {
    transform: translateY(calc(100vh + 120px));
  }
}

Javascript

const rainContainer = document.querySelector(".rain-container");

// background Colors for the raindrop
const background = [
  "linear-gradient(transparent, aqua)",
  "linear-gradient(transparent, red)",
  "linear-gradient(transparent, limegreen)",
  "linear-gradient(transparent, white)",
  "linear-gradient(transparent, yellow)"
];

const amount = 100; // amount of raindops
let i = 0;

// Looping and creating the raindrop then adding to the rainContainer
while (i < amount) {
  //  Creating and Element
  const drop = document.createElement("i");

  //   CSS Properties for raindrop
  const raindropProperties = {
    width: Math.random() * 5 + "px",
    positionX: Math.floor(Math.random() * window.innerWidth) + "px",
    delay: Math.random() * -20 + "s",
    duration: Math.random() * 5 + "s",
    bg: background[Math.floor(Math.random() * background.length)],
    opacity: Math.random() + 0.2
  };

  //   Setting Styles for raindrop
  drop.style.width = raindropProperties.width;
  drop.style.left = raindropProperties.positionX;
  drop.style.animationDelay = raindropProperties.delay;
  drop.style.animationDuration = raindropProperties.duration;
  drop.style.background = raindropProperties.bg;
  drop.style.opacity = raindropProperties.opacity;

  //   Appending the raindrop in the raindrop container
  rainContainer.appendChild(drop);
  i++;
}
