Problem 2B. Design and implement an HTML/CSS/JavaScript calculator app that with a layout something like this: Operand 1: Operand 2: Result: + 07 Clear All To perform a calculation, enter the input operands and select the operation (+, -, *, or /) with the corresponding radio button. Then execute the calculation by clicking in the Result textfield. The ClearAll button should clear all three textfields. Write CSS code to change the font to something other than Times New Roman. Also write CSS code to set the layout and colors. Feel free to improve on the suggested layout
