Usage Examples

Basic Implementation

// Initialize animated cards
const cards = new AnimatedCards('.cards-container');

// Add event listeners
window.addEventListener('addToCart', (e) => {
  // Handle add to cart
  console.log('Added to cart:', e.detail.product);
});

Dynamic Card Management

// Add new card
const newCardHTML = `
  <div class="card product-card">
    <!-- Card content -->
  </div>
`;
cards.addCard(newCardHTML);

// Filter cards
cards.filterCards(card => {
  return card.classList.contains('product-card');
});

// Sort cards by price
cards.sortCards((a, b) => {
  const priceA = parseFloat(a.querySelector('.current-price').textContent.replace('$', ''));
  const priceB = parseFloat(b.querySelector('.current-price').textContent.replace('$', ''));
  return priceA - priceB;
});

Custom Styling

/* Custom card theme */
.card.custom-theme {
  background: linear-gradient(135deg, #667eea 0%, #764ba2 100%);
  color: white;
}

.card.custom-theme .card-title {
  color: white;
}

.card.custom-theme .card-description {
  color: rgba(255, 255, 255, 0.8);
}
