What's the best way to center text?

Question

css

Good afternoon.
I have a slick slider. there is a picture in it and 2 lines of text are inserted, how can I make sure that when the screen width changes, the text always remains in the center?
at first I thought through position left / top, but then I realized that this was somehow not right.
