Animation Patterns
Framer Motion Variants
// Fade in on mount
export const fadeIn = {
initial: {opacity: 0},
animate: {opacity: 1},
exit: {opacity: 0},
transition: {duration: 0.2},
}
// Slide up on mount
export const slideUp = {
initial: {opacity: 0, y: 20},
animate: {opacity: 1, y: 0},
exit: {opacity: 0, y: 20},
transition: {duration: 0.3, ease: 'easeOut'},
}
// Scale on hover (for buttons/cards)
export const scaleOnHover = {
whileHover: {scale: 1.02},
whileTap: {scale: 0.98},
transition: {type: 'spring', stiffness: 400, damping: 17},
}
// Stagger children
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>
