问题描述

如何为跨浏览器透明度提供背景？

How to give cross browser transparency to background only?

我想给予 ul {background：}背景透明只是不想在 ul li a {} 透明。

I want to give transparency to background of ul { background: } only don't want to make text inside ul li a {} transparent.

ul {
    filter: alpha(opacity=50); /* internet explorer */
    -khtml-opacity: 0.5;      /* khtml, old safari */
    -moz-opacity: 0.5;       /* mozilla, netscape */
    opacity: 0.5;           /* fx, safari, opera */
}

推荐答案

您可以使用RGBA颜色。我已经为你做了一个例子：

you can use RGBA colors. I have made up an example for you:

http：/ /jsfiddle.net/ypaTH/

ul {
 background: rgba(255, 255, 255, 0.5) //white with opcaity of 50%
}

ul li {
 color: #fff;
 background: rgba(0, 0, 0, 0.5) //black with opcaity of 50%
}

这里是IE和兼容列表的解决方法：
