会发生什么事情,当我将鼠标悬停在元素div id = f12上时div id = floater会改变背景颜色,但当我将鼠标悬停在div id = f11它上面时,它不会改变颜色,任何人都知道为什么？

非常感谢!

只有严格的CSS解决方案,谢谢!

这里有css供查看

#f11
{
    width: 100px;
    height: 50px;
    position: absolute;
    background: transparent;
    opacity: 1;
    filter: alpha(opacity=0);
    border-width: 1px;
    border-style: inset;
}
#f11:hover + #floater
{
    background:blue;
    width: 320px;
    height: 320px;
    opacity:100;
    right:0;
    filter: alpha(opacity=100);
    float: left;
    position: fixed;
}

#f12
{
    width: 100px;

    background: transparent;
    opacity: 1;
