How did I create this cool effect? | Video and the code is in the comments

I was applying Kevin's height 0 to auto video(https://www.youtube.com/watch?v=B_n4YONte5A) but somewhere in the code I had a couple of other issues, so I changed it a bit and solved my problem but now it's interestingly disappear to the middle 😄 I kinda love it but I don't know where it come from. I belive it has something to do with how I position div to the center (top: 50% left: 50% translateX(-50%) translateY(-50%)) but I don't know why exactly. (Now I see there is not a Tailwind tag in here, I hope I am not breaking any rules.)

The simple trick to transition from height 0 to auto with CSS

Animating or transitioning to and from height auto is, well, not really possible (though it is being worked on!), but luckily, there is actually a solution using CSS Grid that’s really easy to implement! 🔗 Links ✅ Keith J. Grant’s article on this (also includes a flexbox solution): https://keithjgrant.com/posts/2023/04/transitioning-to-height-...
