Launch countdown timer

Hey, well done on this! It's not an easy challenge and you've clearly had a good go at the card flip animation!

Only a few suggestions from me for improvements:

1. Your numbers can't be h2s. They are changing dynamically which is a problem for the accessibility tree - assistive technology will read out all h2s on the page, so it needs to be static content. I would just have them in a span inside an outer HTML block.

2. On mid-sized screens the cards go quite small and very far apart because you're using justify-content: space-between;. instead, I suggest you set that to center and use the gap property to give the cards some space between.

Hope that helps :)

Thank you so much for taking the time to review my solution I learned a lot. I have refined the animation. I hope this is better?
