我正在尝试在此 CSS 动画之上叠加图像。我只是想让它坐在它的中间。我试过使用 z-index 和不同的位置，但我似乎无法让它显示出来。我还想让颜色在鼠标移过不同点时发生变化。
body {
margin: 0;
padding: 0;
}
.container {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
background: linear-gradient(to right, #FFB6C1 10%, #FF69B4 51%, #FFB6C1 100%);
background-size: cover;
animation: animate 60s linear infinite loop;
}
.clouds {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
background: url(https://image.ibb.co/cbYTjf/cloud.png);
animation: animate 60s linear infinite;
z-index:1;
}
.logo{
background-image:url(https://i.vgy.me/7FcUbx.jpg)
z-index: 10;
position:absolute;
}
@keyframes animate {
0% {
background-position: 0px;
}
100% {
background-position: 1063px;
}

您可以通过多种方式实现这一目标。我会考虑使用伪元素作为叠加层或其他东西，但这是一种方法。
我看到的主要问题是您需要为 Logo 定义高度和宽度。
