css - 绝对定位导致水平滚动

Question

我有一个云，它使用 CSS3 动画从屏幕内部移动到屏幕外。当云离开屏幕时，屏幕水平滚动，并不理想。我可以用 CSS 隐藏滚动条，但我想阻止滚动。

#c-2 {
background:url(clouds.png) no-repeat;
width:161px;
height:94px;
position:absolute;
top:40%;
right:0%;
animation:CloudB 20s 1s infinite alternate ease-in-out;
-moz-animation:CloudB 20s 1s infinite alternate ease-in-out;
-webkit-animation:CloudB 20s 1s infinite alternate ease-in-out;
-o-animation:CloudB 20s 1s infinite alternate ease-in-out;
}

@keyframes CloudB {
    0%   { right:0%; top:40%; }
    100% { right:-10%; top:40%; }
}

@-moz-keyframes CloudB {
    0%   { right:0%; top:40%; }
    100% { right:-10%; top:40%; }
}

@-webkit-keyframes CloudB {
    0%   { right:0%; top:40%; }
    100% { right:-10%; top:40%; }
}

@-o-keyframes CloudB {
    0%   { right:0%; top:40%; }
    100% { right:-10%; top:40%; }
}
