<div id="Container">
  <span class='first'>First</span>
  <span class='second'>Second</span>
  <span class='third'>Third</span>
</div>

我希望在以下情况下改变颜色：悬停.

> IF(.first：hover)THEN .first {color：red; }
> IF(.second：hover)THEN .first,.second {color：red; }
> IF(.third：hover)那么.first,.second,.third {color：red; }

没有JS,这可能吗？我可以接受CSS Hacks
