SVG 路径在旋转时从正常位置移动

Question

我有一个svg时钟当我旋转手时它会从它的正常位置移动并且#minute-hand element transform-box属性在这个svg元素中不起作用

注:此SVG代码由illustrator生成

和codependency的另一个演示

@keyframes rotate-hand{
from{transform: rotate(0deg);}
to{transform: rotate(360deg)}
}
/* comment this to see the original hands-shape*/
#seconds-hand, #minutes-hand, #hours-hand{
animation: rotate-hand 5s linear infinite;
transform-box: fill-box;
}
#seconds-hand{
/*   animation: rotate-hand 5s linear infinite; */
/*   transform-box: fill-box; */
}
#minutes-hand{

}
#hours-hand{

}

Answer 1

transform-origin:center是您需要的，但您必须考虑已经应用于seconds-hand的转换。我为它添加了一个g元素

@keyframes rotate-hand{
from{transform: rotate(0deg);}
to{transform: rotate(360deg)}
}
/* comment this to see the original hands-shape*/
#seconds-hand, #minutes-hand, #hours-hand{
animation: rotate-hand 5s linear infinite;
transform-origin:center;
}
#minutes-hand {
animation-duration:2s;
}
#seconds-hand {
animation-duration:1s;
}
