Simple Liquid Glass

A tiny, zero-dependency React component that renders a beautiful “liquid” glassmorphism panel using an SVG displacement map. It supports chromatic aberration, adjustable saturation, gradient borders, a configurable semi‑transparent glass color, and automatic text color based on the surrounding background.

Features

• Liquid glassmorphism with SVG displacement
• Auto text color: detects dark/light backgrounds to keep text legible
• Custom glass color: accepts only semi‑transparent colors (rgba, hsla, hex with alpha)
• Chromatic dispersion and blur with fine‑grained controls
• Adjustable saturation to boost or tame color vibrancy
• Chromatic aberration intensity control to tune the vividness of the edge colors
• Gradient border with masking
• Responsive and content‑agnostic
• TypeScript and tree‑shakable builds (ESM and CJS)

Installation

npm install simple-liquid-glass

or with yarn:

yarn add simple-liquid-glass

Usage

Basic Usage

import React from 'react';
import { LiquidGlass } from 'simple-liquid-glass';

function App() {
  return (
    <div style={{ width: '300px', height: '200px' }}>
      <LiquidGlass autoTextColor glassColor="rgba(255,255,255,0.4)">
        <div style={{ padding: '20px' }}>
          <h2>Your Content Here</h2>
          <p>This content has a liquid glass effect!</p>
        </div>
      </LiquidGlass>
    </div>
  );
}

Advanced Usage with Custom Settings

import React from 'react';
import { LiquidGlass } from 'simple-liquid-glass';

function App() {
  return (
    <div style={{ width: '400px', height: '300px' }}>
      <LiquidGlass
        mode="custom"
        scale={200}
        radius={20}
        border={0.1}
        lightness={60}
        displace={0.5}
        alpha={0.8}
        blur={10}
        dispersion={30}
        frost={0.2}
        glassColor="rgba(255,255,255,0.4)"
        autoTextColor
        textOnDark="#ffffff"
        textOnLight="#111111"
        forceTextColor
        borderColor="rgba(255, 255, 255, 0.5)"
        className="my-glass-container"
        style={{ boxShadow: '0 8px 32px rgba(0, 0, 0, 0.1)' }}
      >
        <div style={{ padding: '30px' }}>
          <h1>Custom Glass Effect</h1>
          <p>Fully customized liquid glass morphism</p>
        </div>
      </LiquidGlass>
    </div>
  );
}

Preset Mode

The component comes with a beautiful preset that works out of the box:

<LiquidGlass mode="preset">
  <YourContent />
</LiquidGlass>

Note: In preset mode, incoming props still override the preset defaults (e.g., scale, radius, blur, etc.). On iOS, when iosBlurMode is 'auto', a minimal blur (iosMinBlur, default 2px) is applied even if blur is 0 to ensure a visible fallback effect.

Props

Examples

Card with Glass Effect

<div className="card-container" style={{ 
  width: '350px', 
  height: '200px',
  background: 'linear-gradient(135deg, #667eea 0%, #764ba2 100%)'
}}>
  <LiquidGlass radius={15} frost={0.15} autoTextColor glassColor="rgba(255,255,255,0.35)">
    <div style={{ padding: '24px', height: '100%' }}>
      <h3 style={{ marginBottom: '12px' }}>
        Glass Card
      </h3>
      <p>
        This is a beautiful glass morphism card with liquid distortion effects.
      </p>
    </div>
  </LiquidGlass>
</div>

Overlay Effect

<div style={{ position: 'relative', width: '100%', height: '400px' }}>
  <img src="background.jpg" alt="Background" style={{ width: '100%', height: '100%', objectFit: 'cover' }} />
  
  <div style={{ 
    position: 'absolute', 
    top: '50%', 
    left: '50%', 
    transform: 'translate(-50%, -50%)',
    width: '300px',
    height: '150px'
  }}>
    <LiquidGlass autoTextColor glassColor="rgba(255,255,255,0.4)">
      <div style={{ padding: '20px', textAlign: 'center' }}>
        <h2>Overlay Content</h2>
        <p>Glass effect over image</p>
      </div>
    </LiquidGlass>
  </div>
</div>

Browser Support

• Chrome (latest)
• Firefox (latest)
• Safari (latest)
• Edge (latest)

The component leverages modern CSS (backdrop-filter) and SVG filters. Older browsers may not support all effects.

Performance Tips

1. The component uses ResizeObserver to adapt to size changes efficiently
2. SVG filters are hardware-accelerated in modern browsers
3. For best performance, avoid animating the glass parameters rapidly
4. Use the preset mode for optimal default settings

Accessibility

• autoTextColor uses computed styles from the nearest opaque ancestor to decide between textOnDark and textOnLight. This helps maintain readable contrast automatically. You can set forceTextColor to enforce the computed color on deeply nested content.

Storybook

Run a live playground:

npm run storybook

Switch the Backgrounds toolbar between light/dark to see text color adapt in real time.
