   Hands-on Project 8-3
   Sung Kim | 7-12-26 | IST-239-W01

   Purpose:
   This project allows customers to build a custom pizza by selecting its size, crust, and toppings.
   Each topping can cover the full pizza or only its left or right side.
   Completed pizzas are stored in a shopping cart and displayed with a summary of their selections.

   This CSS file formats the pizza-building controls, layered topping preview, cart display, and overall page layout.
