不仅在指针位于路径上方时启动悬停操作，而且在指针通常位于图标上方甚至路径之间时启动悬停操作？我不添加任何额外的标记非常重要。 HTML 部分需要保持原样。

Answer 1

将 :hover 移动到 SVG (#icon) 元素，就像使用任何其他 HTML 结构一样:

#icon:hover #p1 {
  opacity: 0.2
}
#p1 {
    fill:none;
    stroke:black;
    pointer-events:all;
}

因为您正在影响整个元素，所以不需要 #p 选择器，因此您可以进一步简化:

#icon:hover {
  opacity: 0.2
}
#p1 {
    fill:none;
    stroke:black;
    pointer-events:all;
}
