   Hands-on Project 9-5
   Sung Kim | 7-19-26 | IST-239-W01

   Purpose:
   This project uses session storage to build and display a shopping cart for a winter clothing website.
   Customers can select a product, quantity, size, and color from one of four product pages.
   Each selected item is stored in session storage and assigned a numbered cart item key.
   The shopping cart page retrieves the stored items and displays their product information in a table.

   This file controls the layout and appearance of the product pages and shopping cart page.

   Filename: styles.css
   Related: product01.html, product02.html, product03.html, product04.html, cart.html
