枫树林给大地铺上了红色的地毯，秋风一吹，枫叶发出哗啦啦的响声，好似在鼓掌欢庆这丰收的景象。看，那菊花，它们开得多么热烈！距么旺盛！黄的、红的、白的、紫的……一朵朵，一簇簇，迎着秋风，披着寒霜，争妍斗艳，喷芳吐香，开得到处都是，简直成了一个锦簇的世界。

代码如下:.transparent_class {filter:alpha(opacity=50);-moz-opacity:0.5;-khtml-opacity: 0.5; opacity: 0.5;}
UPDATE: I wanted to pull this post out of the archives and update it a bit because it there seems to be a good amount of interest in this subject.
Here is what each of those CSS properties is for:
- opacity: 0.5; This is the “most important” one because it is the current standard in CSS. This will work in most versions of Firefox, Safari, and Opera. This would be all you need if all browsers supported current standards. Which, of course, they don’t.
- filter:alpha(opacity=50); This one you need for IE.
- -moz-opacity:0.5; You need this one to support way old school versions of the Mozilla browsers like Netscape Navigator.
- -khtml-opacity: 0.5; This is for way old versions of Safari (1.x) when the rendering engine it was using was still referred to as KTHML, as opposed to the current WebKit.
