How can I make my banner slides responsive on both mobile and desktop?

[FlavioMello]

Hello, I would like my current banners to be responsive, that they adapt to mobile and desktop size.

I currently use the Refresh theme, but I haven't started editing my store yet, so if I need to change that's fine.

If possible : I would also like, if possible, to have a way to click on the slides, to take them to the other page, without the need for a button.

Thanks for any answers.
