如果我有十几个CSS选择器,并想要分配：悬停属性到所有这些,我习惯这样做：
selector,selector2,someOtherSelector,someSelector div {
//some properties
}
selector:hover,selector2:hover,someOtherSelector:hover,someSelector div:hover {
//some properties
}
打字：悬停四次似乎是多余的.有没有办法将选择器分组
(selector,someSelector div):hover {
//some properties
}
代替？
