Carousel would not scale evenly

[compensato]

Hi, i have a quesiton in regard to the carousel: i made a fullscreen slideshow for the homepage of my website https://www.alessandrocugola.com/
i set the frame in a way that it fills the full screen: however when i start scaling down and playing with the browser window size, a white strip appear at the bottom. is there a way to avoid that, and make the carousel visual content always fills in the browser window? i attach a screenshot to see the white strip
