+# 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` |
