Does gulp-concat work with css?

Question

css

It is necessary to put all sorts of css libraries into one file and I remembered about concat . In the examples there is js everywhere ... but is he friends with css?
I know about gulp-concat-css, but the sourcemap support in the first plugin attracts.
Maybe someone has something to advise? And in general, all sorts of bootstrap.min.css, slick.min.css, ... will not break if they are put together?
