Ejemplos de Uso

Implementación Básica

// Inicializar tarjetas animadas
const cards = new TarjetasAnimadas('.cards-container');

// Añadir event listeners
window.addEventListener('addToCart', (e) => {
  // Manejar añadir al carrito
  console.log('Añadido al carrito:', e.detail.product);
});

Gestión Dinámica de Tarjetas

// Añadir nueva tarjeta
const newCardHTML = `
  <div class="card product-card">
    <!-- Contenido de la tarjeta -->
  </div>
`;
cards.addCard(newCardHTML);

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

// Ordenar tarjetas por precio
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;
});

Estilización Personalizada

/* Tema personalizado de tarjeta */
.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);
}
