如何讓圖片像雲一樣的行為?

之前問過了這個類似問題
https://segmentfault.com/q/10...
是如何讓他能來回走動

.img-move{
    animation:imgMove 4s linear infinite;
    -moz-animation:imgMove 4s linear infinite;
    -webkit-animation:imgMove 4s linear infinite;
    -o-animation:imgMove 4s linear infinite;
    position: absolute;
}

@keyframes imgMove
{
0%   {right:100px;}
25%{right:150px;}
50%{right:100px;}
75%{right:50px}
100% {right:100px}
}

現在想問的是
如何讓它像雲一樣,讓圖慢慢移動後,消失?
然後在原本那一端再出現一次圖,不斷循環?

@keyframes imgMove {
    0% {
        right: 100px;
        opacity: 0.5;
    }
    25% {
        right: 150px;
        opacity: 1;
    }
    50% {
        right: 100px;
        opacity: 0.5;
    }
    75% {
        right: 50px;
        opacity: 0;
    }
    100% {
        right: 100px;
        opacity: 1;
    }
}

其實加上透明就行了,動畫內的樣式是可以有多個的。
然後根據你的意思是不是直接寫成下面的就可以了?

@keyframes imgMove {
    0% {
        right: 150px;
        opacity: 1;
    }
    100% {
        right: 50px;
        opacity: 0;
    }
}
