HTML 两个悬停效果不起作用

HTML two hover Effects don't work

所以我正在为网站创建一个菜单,但我无法同时使用这两种悬停效果。我希望当我将鼠标悬停在名称上时,字母会变亮 + 名称下方的白色块应该淡入(不适用于活动名称)但我只得到第一个效果......

这是要看的Jsfiddle。感谢所有帮助:)

HTML:

<body>

    <div id="cssmenu">
        <ul>
            <li class='active'><a href='#'><span>Home</span></a></li>
            <li><a href='#'><span>Products</span></a></li>
            <li><a href='#'><span>Company</span></a></li>
            <li class='last'><a href='#'><span>Contact</span></a></li>
        </ul>
    </div>

</body>

如果你将 hover 添加到 #cssmenu ul li a:before class 你开始得到你想要的了吗?

像这样:

cssmenu ul li a:hover:before
