  • Card Info: This section will include product details such as the name, price, and an “Add to Cart” button.

Style with CSS for the Transition

Next, add CSS to style the product card and create smooth transitions when users hover over it. We will use the z-index property along with other CSS properties like transform and transition to create this effect.
