标签: css hover

当前我的鼠标指针如果红色框中有点它还在做悬停功能,但我需要的是我只需要悬停在红色框中,它开箱即可隐藏菜单。

这是来自JSfiddle http://jsfiddle.net/KECN7/

的源代码

这是我的html源代码

     <ul id="menu">
        <li>
            <a href="#" class="btn-function"></a>
            <ul>
                <li><a href="' . wp_logout_url(home_url()) . '">Logout</a></li>
                <li><a href="#">Account Settings</a></li>
                <li><a href="#">Terms & Policies</a></li>           
            </ul>
        </li>
    </ul>

问题是您是将红色框应用于a元素,而是对(较大的)li父元素执行操作。

您可以将选择器更改为(Fiddle):

#menu li a:hover + ul, #menu li a + ul:hover{
    display: block;
    z-index: 99;    
}

由于aul之间存在死角,这不是一个完美的解决办法,但最好的选择是让a占用整个空间。 li
