That would mean digging into your entire project to find out what’s causing the problem.
Rather, I’d like to see the carousel in isolation so that it becomes easier to single out the bug relating to this specific component. You can do so by replicating just the carousel-related code to something like CodePen and see if you’re getting the same bug. If you are, I can look at it and hopefully make a helpful suggestion. If you’re not, then something else on your project is interfering with the carousel and you can start switching other scripts off to find out what’s causing the issue.
