Please have a look at the following documentation about Personalizing form rendering. What you need to do is basically add the fileds/buttons that you need and override the default css with your own stylesheet or specifications.
There have been some other posts related to CSS in web applications on this forum so don't hesitate browse through it.
Thank you, I will pursue past responses as well. After looking at the documentation, how can we also create/expand our database to include these two new data fields in our customer profile/data?
