基本上你的渐变在顶部有一个固定的颜色,在底部有一个不同的颜色。

如果您将此渐变构建为 2 个不同的渐变叠加,那么您可以移动底部的渐变并根据位置的变化创建颜色变化

div {
    width: 400px;
    height: 300px;
    background-image: 
linear-gradient(to top, transparent, red),    
linear-gradient(to right, green, yellow, blue);
    background-size: 100% 100%, 2000% 100%;
    animation: move 5s infinite;
}

@keyframes move {
 from {background-position: center center, left center;}
 to {background-position: center center, right center;}
}
