> **A lightweight, Vanilla JavaScript Web Component for liquid glass distortion effects.**

Bring your UI to life with real-time SVG displacement filters. This component simulates physical glass refraction, chromatic aberration, and depth. It works in **any** framework (React, Vue, Svelte, Angular) or plain HTML.

---

## ✨ Features

- 💧 **Real-time Liquid Distortion** – Uses advanced SVG filters to bend light.
- 🌈 **Chromatic Aberration** – Prism-like color splitting effect.
- 🎨 **Color Vibrancy** – Control brightness and saturation to make backgrounds pop.
- 🖱️ **Interactive** – Reacts to clicks and presses naturally.
- 📱 **Responsive & Auto-sizing** – Fits your content perfectly.
- 📦 **Zero Dependencies** – Pure Vanilla JS. < 5kb gzipped.
- 🛡️ **Graceful Degradation** – Falls back to standard blur on unsupported browsers.

## 🚀 Installation

### Option A: NPM (Recommended)

Best for modern build setups (Vite, Webpack, Next.js, etc.)

```bash
npm install @real-human/liquid-glass
```

### Option B: CDN (No Build)

Best for static HTML or prototyping.

```html
<script type="module" src="https://unpkg.com/@real-human/liquid-glass/dist/liquid-glass.es.js"></script>
```

---

## 💻 Usage

### 1. In JavaScript Frameworks

Import it once in your main entry file (e.g., `main.js`, `App.js`, or `index.js`).

```javascript
import '@real-human/liquid-glass';

// The component <glass-element> is now available globally!
```

### 2. In HTML

Use the tag directly. The `auto-size` attribute is the magic wand that makes it fit your content.

```html
<glass-element
    auto-size
    blur="5"
    strength="30"
    radius="25"
    saturate="1.2"
>
    <!-- Put anything you want inside -->
    <div style="padding: 2rem; color: white;">
        <h1>Liquid Card</h1>
        <p>Click me to see the effect!</p>
    </div>
</glass-element>
```

## 🎛️ Configuration

You can customize the physics and color of the glass using these attributes:

| Attribute | Type | Default | Description |
|-----------|------|---------|-------------|
| `auto-size` | `boolean` | `false` | **Recommended.** Adapts the glass size to its content. |
| `strength` | `number` | `20` | The intensity of the liquid distortion. |
| `radius` | `number` | `25` | Border radius in pixels. |
| `depth` | `number` | `10` | The simulated thickness of the glass edges. |
| `blur` | `number` | `5` | The background blur amount. Lower values = sharper ripples. |
| `background-color` | `color` | `rgba(255,255,255,0.1)` | The tint of the glass surface. Keep alpha low for clear glass. |
| `saturate` | `number` | `1.1` | Color saturation multiplier (1.0 is normal). |
| `brightness` | `number` | `1.1` | Brightness multiplier (1.0 is normal). |
| `chromatic-aberration` | `number` | `0` | Splits RGB channels (prism effect). Values 2-5 look best. |
| `debug` | `boolean` | `false` | Shows the raw displacement map for debugging. |

## 🧪 Glass Recipes

Different settings create vastly different materials.

### 🧊 Crystal Clear Water

Best for high-end UI where you want to see the background clearly with sharp liquid edges.

```html
<glass-element 
    blur="2" 
    background-color="rgba(255, 255, 255, 0.05)" 
    strength="50"
    saturate="1.2"
>
    <!-- Content -->
</glass-element>
```

### 🌫️ Frosted Ice

Best for readability when placing text over busy backgrounds.

```html
<glass-element 
    blur="15" 
    background-color="rgba(255, 255, 255, 0.4)" 
    strength="20"
>
    <!-- Content -->
</glass-element>
```

### 🌈 Prism Oil

Heavy distortion with color splitting.

```html
<glass-element 
    strength="80" 
    chromatic-aberration="5" 
    saturate="1.5"
>
    <!-- Content -->
</glass-element>
```

## 🌍 Browser Support

This component relies on **SVG Filters inside Backdrop Filter**, a cutting-edge CSS feature.

| Browser | Status | Experience |
| :--- | :--- | :--- |
| **Chrome / Edge / Arc / Brave** | ✅ Supported | Full liquid distortion & chromatic aberration. |
| **Firefox / Safari** | ⚠️ Fallback | Displays a clean, standard "Frosted Glass" effect (no liquid distortion). |

> **Note:** The component detects browser support automatically. If liquid effects aren't supported, it gracefully degrades to a standard `backdrop-filter: blur()`, ensuring your UI never looks broken.
