CSS: How to make a gradient animation and improve your websites

Hello World! The second episode of the series - A CSS/JS trick in 5 minutes - Last Article was about a Javascript trick (How to have a random background color change). This time I want to show you a CSS trick: How to make a gradient animation.

We need two things, first to style the div that will be animated (it can also be the body):

.container {
/*Marine gradient: Grey, blue, violet, grey again */
  background: linear-gradient(
    -45deg,
    #bdc3c7,
    #2c3e50,
    #c33764,
    #1d2671,
    #141e30,
    #6dd5ed
  );
  background-size: 400% 400%;
  animation: backgroundChange 15s ease infinite;
}
Enter fullscreen mode Exit fullscreen mode

I recommend you to write a comment in the code with the colors rather than just Hex values. Remember that the last hex in code will be the first color displayed. Change the animation direction with the degrees parameter (in this case, the animation will go from top left to bottom right). You can also change duration in seconds and animation type after that.

Then you add the animation. In reality colors don't change, we are just moving the background:

@keyframes backgroundChange {
  0% {
    background-position: 0% 50%;
  }
  50% {
    background-position: 100% 50%;
  }
  100% {
    background-position: 0% 50%;
  }
}
Enter fullscreen mode Exit fullscreen mode

You can easily add parts (25%, 75%) to change the animation how you need.
