Note: The browsers display format is set as per your local machines calendar format.
Since you are using input type Date browser considers its own internal datepicker.
So every browser has its own styling, which makes for a different user experience across platforms.
So it is impossible to change the format in Date Input.
As HTML5 date input specification refers to the RFC 3339 specification, which specifies a full-date format equal to yyyy-mm-dd.
This format is used by the value HTML attribute.
