Chat illustration app, + darkmmode and animations. You'll love it!

This Is my first intermediate challenge here and I'm very happy about it, achieved good results and the best part is that it felt a little simple! Please please please, check out the dark mode. Just switch your phone to darkmode to see the dark if you can (they're no buttons to switch to dark mode yet, I don't know js yet.😅). I'm always open to reviews, advices and feedback, let me know what I did wrong. I'll appreciate 🤲🏾 Also, I had problems changing that white colour of the radio button I ended up leaving it like that, anyone has an idea of how I can do it?
