# SSRIMS Mobile Responsive Implementation Guide

## How to Add Responsive CSS to All Pages

To ensure the responsive CSS is loaded on all pages, add this line to the `<head>` section of each PHP/HTML file:

```html
<link rel="stylesheet" href="../assets/responsive.css">
```

### Pages that Already Have Responsive Updates:
✓ views/start.php
✓ views/auth.php  
✓ All modals (modal_style.css updated)

### Files That Need the responsive.css Link Added:
Add `<link rel="stylesheet" href="../assets/responsive.css">` to:
- views/Dashboard.php
- views/Inventory.php
- views/Accounts.php
- views/Accounts_archive.php
- views/Inventory_archive.php
- views/Categories.php
- views/Logs_pricing.php
- views/Logs_restocking.php
- views/Logs_transactions.php
- views/Point_of_sale.php
- views/Product_registrations.php

### Quick Implementation:
1. Open each major view file
2. Find the `<head>` section
3. Add this line right after other stylesheets:
   ```html
   <link rel="stylesheet" href="../assets/responsive.css">
   ```
