Project upgrade from ionic 3 to ionic 7 - css

Hi, i am updating an old ionic project to the latest version. It was clear to me that many things were going to change, but what I did not expect is that the .css from the old project would not be applied to the new one.

I don’t know if I’m missing something, but the views come out very different.

Have there been any changes to the .css as well? Can they be seen somewhere?

Thank you.

I think you will need to do a complete rewrite
