## 📝 CSS Media Queries Used

@media (max-width: 768px) {
    /* Flex layouts adjust */
    /* Navigation becomes horizontal */
}

/* Mobile Styles - iPhone XR Target */
@media (max-width: 414px) {
    /* Full responsive mobile layout */
    /* Icon-only navigation */
    /* Full-width forms */
    /* Horizontal scroll tables */
}
```

---

## 🛠️ If You Need Further Customization

### To Modify Breakpoints
Edit `assets/style.css` and `assets/responsive.css`:
- Change `@media (max-width: 414px)` for different mobile sizes
- Add new breakpoints as needed

### To Adjust Spacing
Look for:
- `padding: 10px` → adjust for more/less space
- `gap: 8px` → adjust spacing between elements
- `min-width: 44px` → adjust touch target size

### To Modify Colors
Edit `:root` variables in `assets/style.css`:
```css
:root {
    --negative: rgb(209, 54, 54);
    --positive: rgb(255, 196, 0);
    /* ... other colors ... */
}
```

## 📞 Troubleshooting

### Sidebar not collapsing on mobile?
- Ensure `assets/script.js` is loaded
- Check browser console for JavaScript errors

### Forms overflow on mobile?
- Verify `responsive.css` is linked
- Check for `width: 100%` on input fields

### Tables not scrolling?
- Ensure table-responsive styles are active
- Check `.table_wrap` has `overflow-x: auto`

### Modals too small/large?
- Check modal max-width in `modal_style.css`
- Adjust padding and font sizes as needed
