过程

注意，直接在body上加height:100%可能也会出现height为0的情况，这是需要令html的height:100%

代码

html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>CSS-Color-Changing-Background</title>
    <link rel="stylesheet" href="style.css">
</head>
<body>
    
</body>
</html>

css

html {
    /* 若没有这行可能导致body的height为0 */
    /* Edge浏览器中没有这行body也有高度，且占满整行 */
    height: 100%;
}

body {
    height: 100%;
    animation-name: colorChange;
    animation-duration: 10s;
    animation-iteration-count: infinite;
    animation-delay: 0s;
    background-color: rgb(255, 255, 255);
}

@keyframes colorChange {


    0% {
        background-image: linear-gradient(120deg, #a18cd1 0%, #fbc2eb 100%);
    }

    20% {

    }

    30% {

        background-image: linear-gradient(120deg, #0fd850 0%, #f9f047 100%);
    }

        background-image: linear-gradient(120deg, #b224ef 0%, #7579ff 100%);
    }

    80% {
        background-image: linear-gradient(120deg, #df89b5 0%, #bfd9fe 100%);
    }

    100% {
        background-image: linear-gradient(to right, #0acffe 0%, #495aff 100%);
    }
}
