- Code editor: VS Code (or any HTML editor)
- Browser: Chrome, Firefox, or Safari (for testing)
- Basic knowledge: HTML structure, CSS (flexbox/grid), JavaScript (DOM, events, arrays)
- No build tools needed - single HTML file!
Time to complete: 2-3 hours
No build tools or servers needed! This is a single HTML file that runs anywhere.
- Create a new folder called
EliteCommerce - Save the code below as
index.html - Double-click
index.htmlto open in your browser - Start shopping! (Demo login:
admin/admin123)
EliteCommerce/ ├── index.html (all HTML + CSS + JS in one file!) └── README.md (this tutorial)
No terminal needed - just open the file! Windows: Double-click index.html Mac: Right-click > Open with Chrome Or drag index.html to any browser
✅ That's it! Your e-commerce site is live instantly.
Now let's build EliteCommerce from scratch! We'll break your single HTML file into logical parts.
Create the basic folder and main HTML structure:
<title>EliteCommerce</title> ```What this does: Sets up responsive viewport and clean document structure.
Step 2: Core Layout/UI (Header + Page Navigation) Add the header and page system:
Step 3: Main Features (Products + Cart Logic) 3A: Products Array + Render Function const products = [ { id: 1, name: "Smart Watch Pro", price: 1999, emoji: "⌚", category: "electronics" } // ... more products ];
function renderProducts(productsToRender) {
document.getElementById('productList').innerHTML = productsToRender
.map(p => <div class="product-card"> <span class="product-emoji">${p.emoji}</span> <h3>${p.name}</h3> <div class="product-price">₹${p.price}</div> <button onclick="addToCart(${p.id})">Add to Cart</button> </div>).join('');
}
3B: Cart State + Add/Remove
let cart = []; // Global state
function addToCart(productId) { const product = products.find(p => p.id === productId); const existing = cart.find(item => item.id === productId);
if (existing) { existing.quantity++; } else { cart.push({ ...product, quantity: 1 }); } updateCartBadge(); // Updates cart count in header } What this teaches: Array methods (map, find), template literals, state management without frameworks.
Step 4: Styling & Finishing Touches Add your CSS variables and key animations: :root { --primary: #0066ff; /* Blue theme / --dark: #0a0e27; / Dark background */ }
.product-card { background: var(--dark-card); border-radius: 20px; transition: all 0.4s ease; /* Smooth hover */ }
.product-card:hover { transform: translateY(-10px); /* Lift effect */ box-shadow: 0 15px 50px rgba(0,0,0,0.5); } Polish features:
Login modal (demo: admin/admin123)
