You have just started as a front-end developer at your new job. Your first project is to make a simple calculator website. Your responsibility is to create the user interface for the calculator code other developers have already written.
You will need to add buttons for the numbers 0-9, each operation (addition, subtraction, multiplication, division, total), and a clear button. You may change the HTML as you need, but there must be a tag with the id screen
to display the output.
You may style the calculator as you see fit, although a grid layout for the buttons is preferred.
