Glassmorphism Pattern

Create frosted glass effects for overlays and floating UI elements.

Core Classes

// 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.

<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)

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

Subtle Glass (minimal effect)

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

Strong Glass (prominent effect)

<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

<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

<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

<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)

<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
