In Canada they often will require your postal code to be all uppercase and if there's a space between the um first three and the last three And sometimes they want it and sometimes they don't want it So I've become a pro at being like your postal code is invalid. The iOS keyboard likes to you know Show you certain keys based on what type of inputs you're entering. If it's not showing me the the at sign because it's not expecting this to be an email or something I'm gonna lose my mind doing that kind of stuff But either way proper inputs will validate themselves at an html level In a way that makes it so you have to do way less work.
