我试图在css background-image中添加多个背景来创建一个小雪动画。我有6张图片:
snow_big,snow_medium,snow_small,snow_man,tree1和tree2
如果仅使用4个图像用于动画,我的动画效果很好,但是当我添加更多图像时。雪动画停止工作它的唯一动画从左到右但不是从上到下或有时可能停止。这种情况只发生在
.xmas_theme_animation {
background-color:navy;
height:115px;
width:345px;
background-image: url('../images/snow_big.png')
,url('../images/snow_medium.png')
,url('../images/snow_small.png')
,url('../images/snow1_snowman.png')
,url('../images/tree1.png')
,url('../images/tree2.png');
background-repeat: repeat, repeat, repeat, no-repeat, no-repeat, no-repeat;
background-position: 0 0, 0 0, 0 0, 6% bottom, 20% bottom, 40% bottom;
animation: snowfall 10s infinite linear;
}
@keyframes snowfall {
from {background-position: 0 -340px, 0 -172.5px, 0 0px, 6% bottom, 20% bottom, 40% bottom; }
to {background-position: 0 345px, 661px 172.5px, 0 345px, 6% bottom, 20% bottom, 40% bottom;}
}
在css中使用多个背景是否有任何限制? 感谢

不要在@keyframes上使用百分比(%)值作为背景位置。请改用像素(px)值。 当您使用百分比时,动画停止在IE上工作,而它仍然适用于其他浏览器。我在IE和Chrome上对jsfiddle进行了实验。看一看。所有6张图片都是动画,即使在IE上也是如此。 http://jsfiddle.net/qLtxr/
