Load different CSS files for different browsers

[Sehboo]

I also posted this in C# group, but haven't received the answer.

I have a CSS file which shows things perfectly in IE, but it doesn't
work in Opera. If I change the CSS file for opera then it doesn't work

in IE. We only support these two browsers.

What I need to do is find out which browser I am in. If it is IE then
load CSS1. If I am in opera then load CSS2.


it is a C# web application


How would I do this?


thanks
