分享三个不错的css动态渐变背景

第一个

body:before {
    content: "";
    position: fixed;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
    z-index: -520;
    pointer-events: none
}

body:before {
    background: linear-gradient(90deg,#f795331a,#f370551a 15%,#ef4e7b1a 30%,#a166ab1a,#5073b81a,#1098ad1a,#07b39b1a 86%,#6dba821a)
}

第二个

body {
margin: 0;

    radial-gradient(closest-side, rgba(254, 234, 131, 1), rgba(254, 234, 131, 0)),
    radial-gradient(closest-side, rgba(170, 142, 245, 1), rgba(170, 142, 245, 0)),
    radial-gradient(closest-side, rgba(248, 192, 147, 1), rgba(248, 192, 147, 0));
background-size:
    130vmax 130vmax,

background-repeat: no-repeat;
animation: 10s movement linear infinite;
}

@keyframes movement {

25% {

}
}

第三个

* {
box-sizing: border-box;
margin: 0;
padding: 0;
}
body {
overflow:scroll;
overflow-x:hidden;
width: 100vw;
height: 100vh;
background: linear-gradient(
          135deg,
          hsl(170deg, 80%, 70%),
          hsl(190deg, 80%, 70%),
          hsl(250deg, 80%, 70%),
          hsl(320deg, 80%, 70%)
);
background-size: 200% 200%;
animation: gradient-move 15s ease alternate infinite;
}

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