Zero-Shift UI: Managing Layout Stability in High-Animation Sites
High-fidelity animation shouldn't come at the cost of performance metrics. Achieving a 0.0 CLS score in an animation-heavy site like Corvix requires precise engineering.
1. Aspect Ratio Containers
By pre-defining the dimensions of WebGL canvases and animation containers, we prevent the browser from recalculating layout as assets load.
2. GSAP Performance Patterns
Using 'transform' and 'opacity' exclusively for animations ensures that the work stays on the GPU, avoiding expensive layout repaints on the main thread.
3. Critical Asset Prioritization
Ensuring that fonts and primary UI elements are hydrated before complex 3D scenes begin prevents the 'jump' effect often seen in modern web apps.
