A responsive English-language front-end e-commerce project written in vanilla HTML, CSS and JavaScript.

• Searchable 9-product demo catalog
• Filter products by category
• Sort by ascending or descending price
• Add and remove items from cart
• Change item quantities and recalculate totals
• Persist the cart in localStorage
• Simulated checkout that saves a local order history

Open index.html in a browser or serve the directory with any static web server.

In a standalone repository, open Settings → Pages and select Deploy from a branch, main, /(root).

• index.html — storefront markup
• style.css — shared styles
• script.js — search, filtering and cart operations
• README.md — documentation

Important: This is a front-end portfolio demo, not a live shop. Checkout does not accept money, place real orders or collect card information.
