💡 Frontend Tip
Optimize CSS animations
Use will-change to hint the browser for GPU acceleration. Example:
.card {
transform: translateY(0);
transition: transform 0.3s ease;
will-change: transform;
}
Reduces layout thrashing, improves performance for dashboards, modals, or scrolling lists. Avoid overusing to prevent memory overhead.
