Faced the problem of adjusting the parameters of the card and everything that is located on it. I can't set the size of the card I need and besides that, I can't set the sizes of buttons and textfields.
It looks like this on fullscreen: Screen
In small view like this: Screen
But I had to pick balance between kv file and python file. I want to have 1 size always, without changing on full screen. Please, tell me where I have mistake.

After setting card's parameters (thanks to @ApuCoder 's advice) I faced another problem with card (when it opens) like this: screen
Problem with lagging card was solved this way:
class MainScreen(MDScreen):
dialog = None
def add_user(self):
if not self.dialog:
self.dialog = MDDialog(
size_hint=(None, None),
width=400,
type="custom",
content_cls=RegCard(),
radius=[25, ],
auto_dismiss=False,
)
self.dialog.open()
I pulled 'dialog = None' out of every function to the class MainScreen.
