Feedback - Build a Survey Form (almost done)

Hey,
I really need your help guys. First of all I can’t figure out how to fix 15th and 16th step to finish request. I know there is some mess in my code but I don’t know what to do.

Secondly could you advice me or show me somehow how to improve responsiveness of that project, I’m not satisfied with this at all. It works but looks terrible, and I don’t like the way I did it. Maybe there is another faster way to make it looks good on mobile and desktop?

PS Any advices welcome!

Thanks in advance :slight_smile:

EDIT: Or could you just tell me where to search mistake? Is it survey2 tag in html?
