How to crop image in Bootstrap3 slider?

Question

css

Tell me please.
How to make the image in the Bootstrap3 slider display full screen height and 100% width. But the proportions must be preserved (that is, the image should not stretch, but should be cropped if there is too much).
Here I am asking:

img {
  height: 100vh;
  width: 100%;
}

and the picture naturally "floats", but it is necessary that it be the entire width of the slider, and what does not fit is cut off (like the background-size: cover property)

Answer 1

object-fit: cover
