EASY: Reproduce an existing single webpage

The project is to reproduce the following webpage: [login to view URL], with the following requirements: 1. Same responsive layout, except that the menu bar bar on top should desapear. 2. The paragraph above the two white field should be deleted. 3. The bottom bar should remain, with the following text: "All rights Reserved". 4. The form fields should not be named "Width Of Child Element In px" and " Width Of Parent Element In px", but they should be: "First value"; "Second Value"; "Third Value". 5. You'd have therefore three form fields instead of two. 6. The automated result in the "Total: %" space should be named "Result: %". 7. The calcul that should be automatically computed in the Result field (keeping the same smooth design effect on the original website) must be: (Second Value / First Value)^(1/Third Value)-1 Please let me know should you have any question.
