html - 影响文本的CSS不透明度过渡

Question

我的导航栏有问题..尝试仅使用 html 和 css 复制“Dragon interactive”导航(这仍然是新的，所以我还不能处理 javascript 或 jquery!!)。 由于渐变背景上的过渡在 css 上不可用，我尝试了不透明度......对于背景来说似乎工作得很好但是当鼠标悬停时导航栏文本消失了!任何想法家伙如何简单地克服这个问题!!(仅限 css :p) html

<div class="wrapper">
<div class="container"><ul class="menu" rel="sam1">
<li class="active"><a href="#">Acceuil</a></li>
    <li><a href="service.html"><span>Services</span></a></li>
    <li><a href="#">assistance</a></li>
    <li><a href="http://www.ats.dz" target='_blank'>Produits</a></li>
    <li><a href="#">Contacts</a></li>
</ul>
</div></div>

好吧，这是因为这条线:

ul li a:hover {
    opacity:0;
}
