鱼的生成方式是在div的background里面，代码是网上找的：
#fish{
width: 174px;
height: 126px;
position: absolute;
left:0;
top:0;
background:url(image/fish8.png) no-repeat left top;
animation:active1 0.8s steps(8) infinite;
}
@keyframes active1 {
0%{
}
100%{
background-position: left -1008px;
}
}
现在鱼相当于一个背景，但我想让鱼跟我设定的路径x，y坐标来走，应该怎么实现
