Hey people,
this is my first post plz be easy on me 
I’m working on a prototype, specific on an email login.
I want an error message to appear when the user enters the wrong email format.
The “right” format/syntax should be:
text1@text2.text3
text1: username or some other wording
text:2: host
text: com, de or somthing else
The error message should appear on “OnLostFocus” and of course, the conditions for the error message are true.
How is the case-logic I must use for this to work ?
I guess, I need variables for this ?
or
I know I could use the textfield type “email”. But is it possible to edit the style?
On default the field has a red border as long as the wrong format is entered.
friendly greetings
