Create a handler for the slider’s
change event. As the value of the
slider changes, show the number next to the label for the
slider.
As an extra challenge, change the color of the number (or the label) to reflect the intensity of the caffeine strength. Use green for weaker coffee, yellow for regular strength coffee, and red for very strong coffee.
