Answer 1

Use active property when choosing the buttons...

And CSS is good but make the calculator little bit bigger than its present size.

Answer 2

functionalities to add:

memory, undo/redo, auto reset after result (on new button typed), scientist function (square root, cube root, log, cosinus, sinus, tangente and arc of three, 1/x, exponentiation, square and cube shortcut...)

handling etrors:

must avoid eval() basic solution, and handle your calculator functionalities through a real js script, rather than simply inlined functions ;P

check this one:

the styling is not excellent, but responsive and almost all functionalities enumerated previously are implemented, as a real script avoiding eval() ^^
