> We should also look at historical discussion around `<input type=tel>`, as HTML opted not to enforce any structure. See https://html.spec.whatwg.org/multipage/input.html#telephone-state-(type=tel):telephone-state-(type=tel)-2: > Unlike the _URL_ and _E-mail_ types, the _Telephone_ type does not enforce a particular syntax. This is intentional; in practice, telephone number fields tend to be free-form fields, because there are a wide variety of valid phone numbers. Systems that need to enforce a particular format are encouraged to use the `pattern` attribute or the `setCustomValidity()` method to hook into the client-side validation mechanism. -- You are receiving this because you are subscribed to this thread.
