PING Coming Soon Page: Did I make it responsive and accessible enough?

Hello everyone! 👋

I love doing all these challenges and finished another one, it's my ninth one! 🎉

I have been self-learing HTML and CSS since May 2021 and I want to become a developer, so any constructive criticism is very welcome. 😊

❓️ Specific Questions ❓️

1. I wanted to make this one as responsive as possible. I think I managed to do that, but please give me tips on how to improve or point out things where I did a good job.

2. I tried to take accessibility into account when making this page. I have no experience with it, so please tell me what I did right and where I can improve.

Thank you very much for any support you can give me. I love all the small tips and tricks the community gives me. 🙏

Have a nice day! 🙋‍♂️
