wordpress - Resize images on a carousel

Question

I am working on a wordpress site using the Morrison hotel theme. This theme has a fairly large slider in the middle. I find it far too tall in height. However, when I decrease the height of the owl-carousel div for example, the size reduction is done well but the images are not resized. I end up with the top of the image. I guess the problem is that I want to keep my ful-width display but reduce the height... Could you give me a hint to reduce the size in height of the slider and keep the right proportion of the photos? I tried to give you a snippet here but otherwise the site address is https://hotel-restaurant-la-borie.fr/
