Glacial Peak 3D Accordion
Live Preview
A high-end accordion component featuring a 'Mountain' theme. It blends glassmorphism with dynamic 3D physics. The interface utilizes Anime.js for spring-based motion, providing a tactile, organic feel to the expansion mechanics. A subtle 3D tilt follows the user's cursor, creating depth and immersion, while the semi-transparent layers evoke the crystalline structure of glacial ice. Perfect for adventure-themed websites or premium portfolios.

Frequently Asked Questions
How does the Glacial Peak 3D Accordion calculate the dynamic rotation values for the 3D perspective tilt without causing visual jitter during rapid mouse movement?
The component utilizes a normalized coordinate system where the mouse position is mapped between -1 and 1 relative to the container's center. These values are passed into a CSS variable-driven transform: rotateX() and rotateY() function. To prevent jitter, the values are smoothed using a linear interpolation (LERP) coefficient of 0.1 within a requestAnimationFrame loop, ensuring the 3D glassmorphic layers transition fluidly even with erratic cursor paths.
What specific Anime.js parameters are defined in the spring physics configuration to simulate the 'tactile' organic expansion of the accordion panels?
The expansion mechanics leverage the Anime.js spring function with a configuration of 'spring(1, 90, 15, 2)'. This translates to a mass of 1, stiffness of 90, damping of 15, and an initial velocity of 2. This specific balance creates a slight overshoot upon opening, mimicking the physical elasticity of ice under pressure before settling into the fully expanded state, while the 'height' property is animated simultaneously with 'opacity' for a seamless reveal.
How are the backdrop-filter and CSS linear gradients layered to maintain the crystalline glassmorphism effect without breaking the 3D transform-style: preserve-3d context?
The component employs a stacked pseudo-element strategy. The ::before element handles the 'backdrop-filter: blur(15px) saturate(180%)' to create the frosted effect, while the ::after element applies a 'linear-gradient(135deg, rgba(255,255,255,0.3) 0%, rgba(255,255,255,0) 100%)' to simulate light refraction. By setting 'transform-style: preserve-3d' on the parent and 'translateZ(1px)' on the content layers, we prevent the browser from flattening the transparency effects during the tilt interaction.
In the mobile-first implementation, how is the micro-interaction on the chevron handled when the 3D tilt is disabled for performance on low-end handheld devices?
When a touch-primary device is detected via media queries or feature detection, the 3D mouse-tracking logic is bypassed in favor of a 2D CSS transition. The chevron's micro-interaction remains dynamic by using a 'transform: rotate(180deg) scale(1.2)' keyframe animation triggered by the 'aria-expanded' state. This ensures that the 'Mountain' theme's tactile feedback is preserved through scale and rotation rather than depth, maintaining a high-end feel on mobile hardware.
Can the mountain-themed accents be programmatically color-shifted for a 'volcanic' or 'sunset' variant without refactoring the core Anime.js logic?
Yes, the component is built using CSS Custom Properties (Variables) for the primary accent colors, such as '--glacier-primary' and '--peak-highlight'. The linear gradients and SVG mountain masks reference these variables. By updating these variables at the root level or via a theme-provider class, the spring-based expansion and 3D tilt physics remain untouched while the visual aesthetics transition to a 'volcanic' palette using deep reds and oranges.
