Glassmorphism Pattern

Create frosted glass effects for overlays and floating UI elements.

Core Classes

tsx

// Standard glassmorphic container
<div className="bg-black/20 backdrop-blur-md border border-white/10">
  ...
</div>

Variations

Dark Overlay (on images/media)

Best for controls overlaid on images or video.

tsx

<div className="bg-black/20 backdrop-blur-md border border-white/10 rounded-full px-3 py-2">
  {/* Content */}
</div>

Light Overlay (on dark backgrounds)

tsx

<div className="bg-white/10 backdrop-blur-md border border-white/20 rounded-xl px-4 py-3">
  {/* Content */}
</div>

Subtle Glass (minimal effect)

tsx

<div className="bg-black/10 backdrop-blur-sm border border-white/5 rounded-lg px-3 py-2">
  {/* Content */}
</div>

Strong Glass (prominent effect)

tsx

<div className="bg-black/40 backdrop-blur-lg border border-white/20 rounded-2xl px-5 py-4">
  {/* Content */}
</div>

Token Reference

Property	Light Glass	Standard	Strong
Background	`bg-black/10`	`bg-black/20`	`bg-black/40`
Blur	`backdrop-blur-sm`	`backdrop-blur-md`	`backdrop-blur-lg`
Border	`border-white/5`	`border-white/10`	`border-white/20`

Common Use Cases

Carousel Indicators

tsx

<div className="absolute bottom-3 left-1/2 -translate-x-1/2">
  <div className="flex items-center gap-2 px-3 py-2 rounded-full bg-black/20 backdrop-blur-md border border-white/10">
    {/* Indicator dots */}
  </div>
</div>

Floating Action Button

tsx

<button className="fixed bottom-6 right-6 p-4 rounded-full bg-black/20 backdrop-blur-md border border-white/10 hover:bg-black/30 transition-colors">
  <Icon className="w-6 h-6 text-white" />
</button>

Tooltip/Popover

tsx

<div className="absolute top-full mt-2 px-3 py-2 rounded-lg bg-black/30 backdrop-blur-md border border-white/10">
  <span className="text-white text-sm">Tooltip content</span>
</div>

Navigation Bar (over hero)

tsx

<nav className="fixed top-0 left-0 right-0 z-50 bg-black/10 backdrop-blur-md border-b border-white/10">
  {/* Nav content */}
</nav>

Text Contrast

When using glassmorphism, ensure text has sufficient contrast:

Background Opacity	Text Color
`bg-black/10` - `bg-black/20`	`text-white` or `text-white/90`
`bg-black/30` - `bg-black/40`	`text-white`
`bg-white/10` - `bg-white/20`	`text-white` or `text-zinc-100`

Performance Note

backdrop-blur can impact performance on lower-end devices. Consider:

Using smaller blur values (backdrop-blur-sm) for frequently updated elements
Avoiding large glassmorphic areas that cover significant viewport
Testing on mobile devices

Checklist

Background has transparency (e.g., bg-black/20)
backdrop-blur-* applied for frosted effect
Subtle border with transparency (border-white/10)
Text has sufficient contrast
Border radius matches design language
Tested on lower-end devices for performance
