[MOTION THEME] How reduce slideshow width on desktop visualization?

[userwithoutname]

It's possible to change only the height of the slideshow but not the width. 

I would like to keep the original aspect-ratio of the images but size reduced (maybe 60%-75% of the original size), and keep it centered.

I'd like this modify just for desktop visualization and not for mobile one.

There are 2 slideshow on the site, the first one (first image of the page) is used as background photo, and i would like to keep that as it is. If possible I would modify only the other one in the middle of the page, the slideshow with 4 photos
