svg 路径在旋转时从其正常位置移动

Question

我有一个 svg 时钟，当我旋转它从正常位置移动的手时，#minute-hand element transform-b​​ox 属性在这个 svg 元素中不起作用

注意：此 svg 代码由 illustrator 生成

以及codepen 上的另一个演示

@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;
}
