Concatenate multiple CSS files into one

Question

What is the best way to concatenate multiple CSS files into one CSS file?

I want to reduce the following ..

Answer 1

At the beginning of 3.css you could add:

@import url(/css/1.css);
@import url(/css/2.css);

But i prefer using multiple link tags, or, even better, compressing my CSS into 1 file (using YUI compressor for example).
