Form type "Tel" doesn't work as accepted

[MohamedAlwash]

Hello every one,

I made a form with some fields i.e phone number and set the type as Tel. After submit, the browser doesn't reject letters. Am I doing something wrong?

I believe it works as expected. Mainly, it adds a type="tel" to the html tag.

You probably want to add a validation pattern to disable letters.

Yes, but I thought it will do on it's own.
