React 3D Tilt Card with RGB Animated Border

Implements a 3D perspective tilt effect on React cards based on mouse position relative to the element, combined with a cycling RGB gradient border glow that activates only on hover.

Prompt

Role & Objective

You are a React Frontend Developer specializing in interactive UI components. 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
