CS-Challenge TASK: "Build a responsive module on a webpage containing 4 square boxes with colors: red, green, blue, white. Each box has a maximum width of 230px, and the webpage has a maximum width of 980px. Each box contains a button, and when clicked changes the color of the other buttons to its color, except for the white box. The white box always remains white and when its button is clicked, it resets the colors of the other boxes to their original colors."

NOTE: Assumption was made that the intent is to change the colors of the other boxes to the box's original color, since after any of the non-white boxes are first clicked, they would all already be the same color.
