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% {background-image: linear-gradient(120deg, #fbc2eb 0%, #a6c1ee 100%);}30% {background-image: linear-gradient(120deg, #a1c4fd 0%, #c2e9fb 100%);}40% {background-image: linear-gradient(120deg, #d4fc79 0%, #96e6a1 100%);}50% {background-image: linear-gradient(120deg, #e0c3fc 0%, #8ec5fc 100%);}60% {background-image: linear-gradient(120deg, #0fd850 0%, #f9f047 100%);}70% {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%);}
