Replace the class .mesh-test with your own as well as the four lines of code 
following right underneath (with the code from Mesher)

.mesh-test{
    background-color:hsla(95,0%,0%,1);
    background-image:
    radial-gradient(at 88% 79%, hsla(227,93%,77%,1) 0px, transparent 50%),
    radial-gradient(at 13% 9%, hsla(80,95%,71%,1) 0px, transparent 50%);



animation: gradient 13s ease infinite;
    background-size: 200% 200%;
}

@keyframes gradient {
	0% {
		background-position: 0% 20%;
	}
	25% {
		background-position: 100% 50%;
	}
	50% {
		background-position: 50% 70%;
	}
	100% {
		background-position: 0% 20%;

}
