title: Merge multiple CSS files together with import
body: <p>I have like 10 CSS files, all of these files are imported into a main.css file, I asked myself if it is possible to like merge all of these imported files together. Now I got a main.css which includes just imports, what I want is a main.css file which includes just CSS from all other files, optionally in different sections with comments that includes the file name. Do you know what I mean and is there any solution?</p>
