Obsidian Helix Spring
Live Preview
A premium dark neomorphic loader that combines the tactile depth of soft-shadow UI with a fluid SVG-based spring animation. The component features a realistic compression effect on a multi-layered coil path, housed within a deeply recessed neomorphic card. Designed for high-end technical interfaces, it uses a subtle color palette of deep charcoal and indigo accents to convey a sense of precision and advanced engineering. The responsiveness is handled through SVG viewBox scaling and CSS transform-origin anchors.

Frequently Asked Questions
How does the Obsidian Helix Spring maintain a constant stroke width during the vertical compression of the coil path?
The component utilizes the 'vector-effect: non-scaling-stroke' CSS property on the SVG path. This ensures that while the scaleY transformation compresses the helix along the Y-axis from the 'transform-origin: center bottom' anchor, the indigo stroke itself does not flatten or lose its structural weight.
What CSS configuration creates the deep neomorphic recession within the charcoal surface?
The 'deeply recessed' effect is generated using a combination of multiple 'inset' box-shadows. Specifically, a heavy dark inset shadow (e.g., 10px 10px 20px #050505) defines the cavity depth, while a subtle highlight inset shadow (e.g., -5px -5px 15px #2a2a2e) defines the upper-left rim, creating the tactile neomorphic 'pit' appearance.
How is the indigo glow optimized to prevent frame drops during the animation's peak oscillation?
Rather than using standard box-shadows which trigger expensive paint cycles, the glow is implemented via 'filter: drop-shadow()' on a hardware-accelerated layer. By applying 'will-change: transform, filter' to the helix container, the browser offloads the indigo glow rendering to the GPU, maintaining a consistent 60fps.
How can the text-cycling animation be synchronized with the mechanical timing of the spring's rebound?
The text-cycling uses a keyframe animation that mirrors the 'animation-duration' and 'animation-iteration-count' of the helix. By sharing a 'cubic-bezier(0.25, 0.1, 0.25, 1.0)' timing function, the text transitions trigger exactly at the moment of maximum spring extension, reinforcing the physical logic of the UI.
For high-density dashboard layouts, how does the component handle scaling without losing its neomorphic detail?
The component employs 'aspect-ratio' locking and SVG viewBox scaling. The neomorphic shadows are defined using relative 'em' or '%' units for blur and spread, allowing the entire card to shrink for mobile or sidebar views while the depth-to-size ratio remains visually consistent with the indigo helix's proportions.
