Of course. Let's give those recommendation cards a powerful, modern, and professional look that suits the Dongcheng power tool brand.

This new design introduces several enhancements:
*   **Modern Card Shape:** A clean white background with a subtle border and rounded corners.
*   **Interactive Hover Effect:** The card will gently lift and cast a shadow when a user hovers over it, creating a dynamic feel.
*   **Image Zoom:** The product image will slightly zoom in on hover, drawing attention to the product.
*   **Professional Typography:** The product title is made bolder and clearer. Prices are styled to easily distinguish between the sale price and the original price.
*   **Refined Colors:** Using a palette of clean whites, strong grays, and an accent color for sales and prices to match a professional brand identity.
*   **Updated Navigation Arrows:** The slider arrows are restyled to be cleaner and more modern.

Here is the complete, updated CSS. Simply replace all the old CSS for this section with the code below.
