How to solve the problem of CSS filters filtering text at the same time

这篇文章主要介绍了关于如何解决CSS滤镜同时过滤文字的问题,有着一定的参考价值,现在分享给大家,有需要的朋友可以参考一下

初用CSS滤镜的朋友可能会遇到这样的问题:给p套上filter:alpha(opacity=50); 滤镜后,里面的文字也随之半透明,这种情况下,我们该怎么办呢?

经过本人查阅大量资料,实验N次终于找到了一个兼容ie6,ie7,ie8以及firefox的css透明滤镜的方法,且看我举例说明.

html代码: 

<p id=”body”> 
<span><龙哥博客>解决CSS滤镜同时过滤文字的问题</span> 
</p>
Copy after login

css代码:

<style type=”text/css”> 
#body{ border:1px solid #c00; background-color:rgba(212,0,0,0.5); background:#f00\9; filter:alpha(opacity=10); width:500px; margin:40px auto; line-height:200%; font-size:14px; padding:14px;} 
</style>
Copy after login

这样的代码并不能解决过滤文字的问题,想要不过滤文字,就必须在CSS代码里加上这行代码:

#body *{ position:relative;}
Copy after login

星号是为了让IE6和IE7执行,火狐和IE8就不执行了,火狐本身来讲就不支持IE特有的滤镜功能,所以这里没必要再加星号,怎么样?很简单吧~
