如果我确定可见度:有人躲在宽松的利元件上,我如何把它 back回头?

例如。

#menu li ul li {
visibility: hidden;
}

我尝试:

#menu li ul li:hover {
visibility: visible;
}

但是,它没有工作——显然,我 have不去yn!

<代码>可视性:隐藏的隐藏了该元素,没有可 h的表面,因此永远不会启动<代码>hover的活动。

Try opacity: 0 (或 甚至opacity: 0.00001<>/code>, 现在无法确定表面是否仍保留在0上,以取得预期效果。 注: IE < 8 需要特殊治疗(filter:alpha(opacity=0)

其他浏览器也需要其他<代码>opacity>环境,并需要核对@Nick Craver的链接,以便有一个完整的清单。

为什么在每一带都不会增加一个孩子的包裹;与这一样(可能是一纸或四):):

<li><p>dadada</p></li>

然后,为了打断:

#menu ul li p {
 visibility: hidden;
}

#menu ul li:hover p {
 visibility: visible;
}
