Prism Flow Gradient Avatar
Live Preview
A sophisticated avatar component featuring a dynamic, multi-stop animated gradient border. The design utilizes a 'double-wrap' technique to create a sharp, high-contrast ring effect that stands out against dark backgrounds. It includes a responsive layout that shifts from a vertical stack on mobile to a sleek, glassmorphic horizontal card on desktop, complete with a functional state-toggling status indicator.

Frequently Asked Questions
How is the 'double-wrap' technique implemented to prevent the animated gradient from bleeding into the central avatar image while maintaining a sharp contrast ring?
The component utilizes a nested container structure where the outer wrapper applies a conic-gradient animation with background-origin set to border-box. An inner pseudo-element or container uses a smaller inset with a solid background color to mask the center, creating a crisp 2px gap that ensures the 'Flow' gradient only occupies the border perimeter without overlapping the image mask.
What specific CSS properties are used to prevent GPU stuttering when the glassmorphism backdrop-filter is active during the mobile-to-desktop layout transition?
To optimize performance, the desktop horizontal card applies backdrop-filter: blur(12px) and saturate(180%) specifically to a layer with will-change: transform. This forces the browser to promote the glassmorphic surface to its own compositor layer, preventing expensive re-paints of the underlying animated gradient border during flexbox reflows.
Can the spring-based hover scaling be modified to support a 'pulse' effect without interfering with the status indicator's absolute positioning?
Yes, by targeting the transform-origin of the inner avatar container while keeping the status indicator as a direct child of the non-scaling outer wrapper. The spring physics (typically stiffness: 400, damping: 25) are applied to the scale property of the image mask, allowing the status bubble to remain fixed in the 'top-right' coordinate space despite the avatar's dynamic expansion.
How does the Interactive Status Toggle dynamically alter the Prism Flow Gradient's color stops and animation velocity?
The component maps the status state (Online/Away) to a set of CSS custom properties. When the state toggles to 'Away', a transition property updates --flow-speed from 2s to 8s and swaps the high-vibrancy stop-colors for a desaturated grayscale palette using a cubic-bezier(0.4, 0, 0.2, 1) timing function for the color interpolation.
How does the high-resolution image masking handle non-square aspect ratios when transitioning from the mobile vertical stack to the desktop glassmorphic card?
The image is contained within a wrapper using object-fit: cover and an aspect-ratio: 1/1 rule. The 'high-resolution' masking is achieved via a CSS mask-image: radial-gradient(circle, black 100%, transparent 100%), which ensures that regardless of the parent flex container's growth on desktop, the avatar remains a perfect circle without pixel distortion or stretching.
