A few things that need to be changed before merging:

• Enter key navigates backward after the first stage
• Back button should be to the left of the text instead of the right
• Confirm password stage should have a gap between the two fields (0.5 or 1 rem)
• Improvements in animation
  • When moving forward a step the text field should come in from the right instead of the left
  • When moving backward a step the text field should come in from the left (Like it does now)
  • When moving forward or back, the existing text field should also move out of the way instead of disappearing
