# Glassmorphism

## CSS

```css
.glass-card {
  background: rgba(255, 255, 255, 0.03);
  backdrop-filter: blur(20px);
  -webkit-backdrop-filter: blur(20px);
  border: 1px solid rgba(255, 255, 255, 0.08);
  border-radius: 20px;
}
```

## Anti-patterns

| ❌ Плохо | ✅ Хорошо |
|----------|-----------|
| `backdrop-filter` без fallback | `background: rgba()` fallback |
| `blur(2px)` — не видно | `blur(20px)` |
| Без `-webkit-` prefix | `-webkit-backdrop-filter` |
