Vintage Digital Drip
Live Preview
A sophisticated loading component that merges the aesthetic of a retro terminal with modern glassmorphism. It features a custom-built canvas pixel-rain system that mimics the 'Matrix' effect but filtered through a warm sepia lens. The design incorporates SVG turbulence filters to create a tactile film-grain texture, evoking a sense of nostalgic technology. The interface is encased in a semi-transparent glass card with a terminal-style header, providing a high-contrast yet soft visual experience suitable for creative portfolios or historical archives.

Frequently Asked Questions
How does the canvas-based pixel rain system manage frame rates and CPU overhead when layered beneath the glassmorphic backdrop-filter?
The component utilizes a requestAnimationFrame loop that renders to an offscreen canvas to minimize main-thread painting. To mitigate the high GPU cost of combining backdrop-filter: blur() with SVG turbulence, the canvas resolution is dynamically scaled by a factor of 0.75, which reduces the pixel-shading workload while the sepia filter masks the slight loss in sharpness.
Which specific SVG filter primitives are used to generate the film-grain texture, and can they be throttled for low-power devices?
The grain is generated using feTurbulence with a high baseFrequency (0.65-0.80) and feColorMatrix to limit the noise to the alpha channel. For low-power devices, the component uses a 'reduced-motion' media query that swaps the dynamic SVG filter for a static noise PNG pattern, significantly reducing the per-frame recalculation of the filter stack.
How can the --vint-sepia-primary and --glass-blur variables be adjusted to prevent the amber-toned pixel rain from failing WCAG contrast requirements?
The component is built with a --contrast-buffer variable that automatically increases the terminal text opacity as the --sepia-intensity increases. By adjusting the --vint-sepia-primary HSL values, users can shift the hue while the system maintains a 7:1 contrast ratio by calculating the luminosity of the underlying canvas-drip via a CSS color-mix function.
Does the progressive loading text state support dynamic injection of console logs from external asynchronous fetch requests?
Yes, the component exposes a text-sequencer method that accepts an array of strings or a Promise stream. It uses a character-by-character typing simulation with a variable delay (50ms-200ms) to mimic legacy terminal speeds, allowing you to pipe real-time server-side status updates directly into the glass card's terminal header.
How does the mobile-first CSS logic handle the '100vh' viewport bug in browsers like Safari while maintaining the fixed-aspect ratio of the terminal header?
The component uses a custom --vh property calculated via a resize listener to define the glass card's height, ensuring the terminal header doesn't get cut off by browser chrome. The pixel-rain canvas is set to 'object-fit: cover', allowing the animation to scale without stretching the individual 'drips' when transitioning from portrait to landscape orientations.
