Animation Patterns
Framer Motion Variants
export const fadeIn = {
initial: { opacity: 0 },
animate: { opacity: 1 },
exit: { opacity: 0 },
transition: { duration: 0.2 },
};
export const slideUp = {
initial: { opacity: 0, y: 20 },
animate: { opacity: 1, y: 0 },
exit: { opacity: 0, y: 20 },
transition: { duration: 0.3, ease: 'easeOut' },
};
export const scaleOnHover = {
whileHover: { scale: 1.02 },
whileTap: { scale: 0.98 },
transition: { type: 'spring', stiffness: 400, damping: 17 },
};
export const staggerContainer = {
hidden: { opacity: 0 },
visible: {
opacity: 1,
transition: {
staggerChildren: 0.05,
delayChildren: 0.1,
},
},
};
export const staggerItem = {
hidden: { opacity: 0, y: 10 },
visible: {
opacity: 1,
y: 0,
transition: { duration: 0.2, ease: 'easeOut' },
},
};
Page Transition Wrapper
import { motion } from 'framer-motion';
import { ReactNode } from 'react';
interface PageTransitionProps {
children: ReactNode;
}
export function PageTransition({ children }: PageTransitionProps) {
return (
<motion.div
initial={{ opacity: 0, y: 20 }}
animate={{ opacity: 1, y: 0 }}
exit={{ opacity: 0, y: -20 }}
transition={{ duration: 0.3, ease: 'easeOut' }}
>
{children}
</motion.div>
);
}
Glass Effect Patterns
Glass Card
<div className="glass-card p-6">
<h2 className="text-lg font-semibold text-text-primary">Card Title</h2>
<p className="text-text-secondary mt-2">Card content goes here.</p>
</div>
Glass Panel (Sidebar)
<aside className="glass-panel w-64 h-screen p-4">
<nav className="space-y-2">
{/* Navigation items */}
</nav>
</aside>
Glass Modal Overlay
<motion.div
className="fixed inset-0 glass-overlay flex items-center justify-center z-50"
initial={{ opacity: 0 }}
animate={{ opacity: 1 }}
exit={{ opacity: 0 }}
>
<motion.div
className="glass-card p-6 max-w-md w-full mx-4"
initial={{ scale: 0.95, opacity: 0 }}
animate={{ scale: 1, opacity: 1 }}
exit={{ scale: 0.95, opacity: 0 }}
>
{/* Modal content */}
</motion.div>
</motion.div>
