HTML elements on exact positions on bacground image

Client created this video: https://streamable.com/ojrbwl The requirement is to recreate it exactly like that, meaning the house images must stay in the exact same positions relative to the background on all screen sizes. Client says that AI told him that its possible. However, when using background-size: cover, the background image automatically adjusts to the screen size, so naturally the elements no longer stay in the exact same positions relative to the image. Is what the client wants actually possible, or am I missing something?
