如何防止图像再次出现（css动画）

在我的动画中，我有两朵云（=wolkje）飘过。但是，我希望这些云在动画期间浮动1次，而不是重复

wolkje1先生{

background-repeat: no-repeat;
position: absolute;
width: 650px;
height: 120px;
top: 3px;
background-size: 110px;
background-image: url(../images/wolkje.png);
animation: wolk 10s infinite linear;

} wolkje2先生{

background-repeat: no-repeat;
position: absolute;
width: 650px;
height: 120px;
top: 190px;
background-size: 110px;
background-image: url(../images/wolkje.png);
animation: wolk 15s infinite linear normal;

} @关键帧沃尔克{

0% {background-position-x: -100px ;}
100% {background-position-x: 1000px}

}从中删除无限

animation: wolk 10s infinite linear;

把它当作-

animation: wolk 10s linear;

---

从中删除

ìnfinite

动画：wolk 10s无限线性

它将阻止动画循环
