Your task is to implement a reusable Product Card component that features a 3D tilt effect based on mouse movement and a vibrant, cycling RGB glowing border that appears only on hover. # Communication & Style Preferences - Use clear, concise technical explanations. - Provide code snippets in JavaScript (React) and CSS. - Ensure the solution handles conditional rendering safely. # Operational Rules & Constraints ## 1. 3D Tilt Effect Logic - Use `useRef` to reference the card container. - Calculate rotation based on the mouse position **relative to the card itself**, not the viewport. - Use `event.nativeEvent.offsetX` and `event.nativeEvent.offsetY` to get coordinates within the element. - Calculate the center of the card (`width / 2`, `height / 2`). - Normalize the X and Y values relative to the center. - Apply a multiplier to determine rotation intensity. - **Crucial:** Cap the rotation using `Math.min` and `Math.max` to ensure the effect is consistent and visually appealing across all cards (e.g., max 10-15 degrees). - Update state (`useState`) for `rotateX` and `rotateY` and apply it via inline styles to the card container. - Ensure `transform-style: preserve-3d` is set on the card container. ## 2. RGB Animated Border Logic - The border effect should be applied to the card container (e.g., class `.proda`). - Use CSS pseudo-elements (`::before` and `::after`) to create the glowing border. - Set the card container to `position: relative` and `overflow: hidden`. - Position pseudo-elements absolutely (`top`, `left`, `right`, `bottom` offsets) to sit behind the content (`z-index: -1`). - Apply a `linear-gradient` background containing multiple RGB colors (e.g., a long list of hex codes) to the pseudo-elements. - Set `background-size` to a large value (e.g., `400%`) to allow the animation to cycle. - Animate `background-position` (e.g., from `0% 50%` to `100% 50%`) to create the cycling color effect. - Use `filter: blur()` on one of the pseudo-elements to create the glow/blur effect. - **Visibility:** The border should only be visible on hover. Use `display: none` by default and `display: block` on `:hover`, or use opacity transitions. - Ensure the card's actual background remains white (or the intended color) and is not covered by the gradient. ## 3. Safety & Conditional Rendering - Always check if `ref.current` exists before accessing properties (e.g., `if (!cardRef.current) return`). - This prevents 'Cannot read properties of null' errors in dynamically rendered lists. # Anti-Patterns - Do not use `clientX` and `clientY` for the tilt calculation, as this causes inconsistent effects based on the card's position on the page. - Do not apply the gradient background directly to the card element itself; it must be on pseudo-elements behind the content. - Do not forget to set `z-index` correctly, or the glow will cover the card content instead of framing it. - Do not omit the `overflow: hidden` on the parent, or the glow may spill outside the intended border area. ## Triggers - create a 3d tilt card effect - add rgb glowing border to card - implement animated gradient border - fix card tilt logic for grid layout - add hover glow effect to react component
