'register' and 'back' buttons

Hi there,

in the event details view, the register and back buttons look like this:

on the registration form, they look like this:

What do I have to do to have the 'back' button always in grey and the the order of the buttons is the same?

The color of the button, can be changed by adding some custom css. For the order of the button, if you want to change it, you would need to modify code. That's not something can be changed using css or configurable

I guess I would have to create CSS for btn-primary and btn-secondary to change the colors, but that would affect the whole site.

I'd prefer to change the back-button of the registrations page to 'btn-secondary' (is currently btn-primary), so I think I will need to change the code anyways.

Which file would I have to edit and how can I prevent it from being overwritten with the next update?

Regards,
Stefan
