+# Pull Request: Fix Copy-Code Console Error
+
+## 📝 Description
+
+This PR fixes the console error in the copy-code utility that was generating unnecessary noise when no code content was found to copy. The changes improve cross-browser compatibility and provide user-friendly visual feedback instead of developer-focused console errors.
+
+**Key Improvements:**
+- Replace console.error with user-friendly visual feedback
+- Add secure context check for modern clipboard API
+- Enhance fallback method for older browsers and HTTP contexts
+- Add mobile device support with setSelectionRange
+- Implement visual success/error states on copy buttons
+- Improve error handling with graceful degradation
+
+Fixes console noise when copy operation fails and ensures copy functionality works across all browsers including Firefox, Safari, and older browser versions.

+## 🧪 Testing Performed
+
+### 📱 Browser Compatibility
+
+- [x] Chrome (Version: Latest)
+- [x] Firefox (Version: Latest)
+- [x] Safari (Version: Latest)
+- [x] Edge (Version: Latest)
+- [x] Mobile Chrome (Device: Android/iOS)
+- [x] Mobile Safari (Device: iOS)
+

+- [x] Tablet (768px - 1199px)
+- [x] Mobile (320px - 767px)
+
+### ✅ Test Cases
+
+1. Copy code blocks in modern browsers (Chrome, Edge, Firefox)
+2. Copy code blocks in older browsers with clipboard API disabled
+3. Copy code blocks on mobile devices
+4. Test copy functionality over HTTP vs HTTPS
+5. Test with malformed code blocks (missing data-code attribute)

+## 💭 Additional Notes
+
+This fix addresses the user experience issue where developers would see console errors during normal website usage. The new implementation:
+
+1. **Gracefully handles all browser scenarios** without generating console noise
+2. **Provides immediate visual feedback** to users about copy success/failure
+3. **Maintains backward compatibility** with older browsers
+4. **Improves mobile experience** with enhanced text selection
+
+The changes are minimal and focused, ensuring no breaking changes to existing functionality while significantly improving the user experience across all browsers and devices.
+
+## 🔧 Technical Details
+
+### Before (Issues):
+```javascript
+if (!codeContent) {
+  console.error('No code content found to copy'); // ❌ Console noise
+  return;
+}
+```
+
+### After (Fixed):
+```javascript
+if (!codeContent) {
+  showErrorFeedback(button, 'No content to copy'); // ✅ User feedback
+  return;
+}
+```
+
+### Cross-Browser Compatibility:
+- **Modern browsers (HTTPS)**: Uses `navigator.clipboard.writeText()`
+- **Older browsers / HTTP**: Falls back to `document.execCommand('copy')`
+- **Mobile devices**: Enhanced with `setSelectionRange()` for better text selection
+- **Failed operations**: Visual feedback instead of console errors
