Survey form project

I did my survey form project but my css code wasn’t saved. Now, when I try to edit it, it doesn’t change the style of the form. What can I do?

Welcome to our community!

Post the entire html and css code here properly formatted. Use the </> button for that purpose. Also, post a link to the challenge.

i want to place my radio and checkbox buttons one below the other but with their respective labels in front of them. but i’m not able to do it. any tips?
btw, i haven’t finish styling yet.
