[SOLVED] How can we add noise to linear-gradient background?

How can we add noise to linear-gradient background?

body{
height: 100vh;
background:
linear-gradient(red, transparent ),
linear-gradient(to top left, blue, transparent),
linear-gradient(to top right, rgb(124, 211, 134), transparent );
background-blend-mode: screen;
}

Solution

It is possible with more than 2 colors using ::pseudo element.

@import "https://cdn.jsdelivr.net/gh/KunalTanwar/normalize/css/normalize.inter.min.css";

body {
  height: 100%;
  display: grid;
  place-items: center;
}

.container {
  width: 150px;
  aspect-ratio: 1/1;
  background-image: linear-gradient(to right, #833ab4, #fd1d1d, #fcb045);
}
.container::after {
  content: "";
  position: absolute;
  inset: 0 0 0 0;
  width: 100%;
  height: 100%;
  mix-blend-mode: multiply;
  background-repeat: no-repeat;
  background-position: center center;
  background-image: url(https://grainy-gradients.vercel.app/noise.svg);
}

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