Topic: I am developing a nested form in rails

I am developing a nested form in rails - a user model that has many answers and answers belong to users, there is also a question model.

but what i am trying to do is have a nested form where a user can have many answers - builder works fine for this 3.times {} etc.. but the problem is I have 30 questions and I need to be able to style each question seperatly some questions are yes no some are multiple choice with 4 answers some have 10 answers, I have tried styling the entire for with js but but this seems really messy and just does not feel right for something that should be so simple.

I have been back and forth on this for weeks so please I hope someone can help me.

Kind Regards Jon
