我知道这个问题之前已经提出过，但从未解决。
有谁知道你是否可以在 Firefox 中交叉淡入淡出背景图像？我知道你可以在 chrome 和 explorer 中制作背景图像动画，但它似乎还不能在 FF 中工作。它使用颜色而不是图像。我没有使用 jQuery

这是我的代码，请帮助！：
body{
background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;}
animation:myfirst 5s infinite;
-moz-animation: myfirst 5s infinite; /* Firefox */
-webkit-animation:myfirst 5s infinite; /* Safari and Chrome */
-o-animation:myfirst 5s infinite; /* Opera */;
-webkit-background-size: cover;}
@keyframes myfirst
