my questions are:

1. what kind of css file this?
2. how reformat looks clean , nice regular css file?

that normal css file. has been minified.

you can unminify css files running them through "beautifiers".

they're called "unminifiers".

typically, "minify" code when you're ready move production in order make file size smaller.
