Hey Nora,
Thanks for your follow-up. The answer to both questions you posed here is that yes, fields can be hidden and the style of the whole page can be modified.
However, while both things are possible, they would unfortunately require code customizations to implement 🙁
We cannot help with code customizations, so to implement the features you describe, you would have to write that custom code or hire a professional developer to write the code for you. We have a list of great developers here → http://m.tri.be/18k1 (and have no affiliation with any of these folks—they’re simply some well-respected names in the community that we’ve compiled to share in situations like this one).
I hope this information is helpful!
George
