How to Change Videos on Scroll in a YouTube Shorts-like Design? [closed]

I’m working on a web project where I want to create a video player similar to YouTube Shorts. The idea is to have a series of videos that change automatically when the user scrolls past the current one. I’ve set up the basic HTML, CSS, and JavaScript, but I’m having trouble getting the videos to change correctly on scroll.

Here’s what I have so far:

console.log("Scroller");

// Get all video player elements
const videoPlayers = document.querySelectorAll('.video-player');

// Initialize a flag to indicate whether the user has interacted with the document
let userHasInteracted = false;

// Add an event listener to each video player to listen for user interaction
videoPlayers.forEach(videoPlayer => {
    videoPlayer.addEventListener('click', () => {
        // Set the flag to indicate that the user has interacted with the document
        userHasInteracted = true;

        // If the video is paused, play it
        if (videoPlayer.paused) {
            videoPlayer.play();
        }
    });
});

// Add an event listener to the container to detect scroll
const container = document.querySelector('.container');
container.addEventListener('scroll', () => {
    videoPlayers.forEach((videoPlayer, index) => {
        const videoOffset = videoPlayer.offsetTop;
        const videoHeight = videoPlayer.offsetHeight;
        const scrollPosition = container.scrollTop;

        // Check if the video is in view
        if (scrollPosition >= videoOffset && scrollPosition < videoOffset + videoHeight) {
            // Play the video if the user has interacted
            if (userHasInteracted && videoPlayer.paused) {
                videoPlayer.play();
            }
        } else {
            // Pause the video if it's out of view
            videoPlayer.pause();
        }
    });
});

Problem:
The video player currently covers the whole webpage, and I want it to look more like YouTube Shorts, where the video player is centered and doesn’t take up the entire screen. Additionally, the videos should change automatically when the user scrolls past the current one.

Question:
How can I adjust my code to achieve this effect? Any help or suggestions would be greatly appreciated!
