Etch-a-Sketch Rebuild

A fun JS project. Things to improve on: - The knobs will stop rotating in a particular direction after a while as continually toggling the classes is not the right way to achieve this. I have tried oh so many ways to fix it but my JS isn't good enough. Anyone have a solution shout me on twitter @ihsaan700. Thanks. - Contain the stroke within the borders. - Make it responsive....
