• Enter a number n and print n is an EVEN/ODD number
  • on a blue background (use a div with class box-primary) if n is EVEN
  • on an orange background (use a div with class box-warning) if n is ODD
• The title tag contains the same text as the div tag, i.e., n is an EVEN/ODD number
• The form is sent via GET and is processed on the same page (on which the form and the entered number should remain visible)
