Object fit utilities decide how an image or video fills its box: object-fit-contain shows all of it, object-fit-cover fills the box and crops, object-fit-fill stretches, object-fit-scale only shrinks and object-fit-none keeps the natural size. Responsive variants like object-fit-md-cover switch per breakpoint.
1All object-fit values
contain, cover, fill, scale and none on the same wide image in square frames.
