Complete page background animation with CSS moving gradient

The above Codepen example shows a moving gradient animation on the whole body of the website.

Code snippet for the animation effect.


     Animation effect on "body"

CSS šŸ‘‡

body {
  background: -webkit-linear-gradient(
  background-size: 400% 400%;
  animation: gradient 5s ease infinite;

@keyframes gradient {
  0% {
    background-position: 0% 50%;
  50% {
    background-position: 100% 50%;
  100% {
    background-position: 0% 50%;

what is actually happening ??

The background size here is 400% 400% and the background is moving. Thus, the animation is happening.

This is a great write-up, thanks for sharing. I particularly appreciate the variety of CodePen examples given.

Could you have a look at Ian Forrest's CSS Gradient Animator and let us know what you think of it?

Also, how does changing the linear gradient degree impact the animation?

Thanks a lot. šŸ¤— Rishav

The CSS Gradient Animator is a great tool. Thanks for sharing getting code snippet by directly setting up the varials. It will be a helpful tool. āœŒ

Check out this example to see how it affects the animation.

In a simple explanation, the value of deg in linear-gradient defines the deg between the line between two gradients and the horizontal line.
