## Implementation Instructions
|
|
|
|
### 1. Add New Files to HTML
|
|
|
|
Add before closing `</body>` tag in all HTML files:
|
|
|
|
```html
|
|
<!-- Error Handler (First) -->
|
|
<script src="/assets/js/error-handler.js"></script>
|
|
|
|
<!-- Enhanced API (Before other scripts) -->
|
|
<script src="/assets/js/api-enhanced.js"></script>
|
|
|
|
<!-- Existing scripts -->
|
|
<script src="/assets/js/shop-system.js"></script>
|
|
<script src="/assets/js/cart.js"></script>
|
|
<script src="/assets/js/state-manager.js"></script>
|
|
|
|
<!-- Accessibility (Last) -->
|
|
<script src="/assets/js/accessibility.js"></script>
|
|
```
|
|
|
|
### 2. Add Responsive CSS
|
|
|
|
Add in `<head>` section:
|
|
|
|
```html
|
|
<link rel="stylesheet" href="/assets/css/responsive-fixes.css" />
|
|
```
|
|
|
|
### 3. Add Main Content ID
|
|
|
|
For skip link functionality, add to main content area:
|
|
|
|
```html
|
|
<main id="main-content">
|
|
<!-- Page content -->
|
|
</main>
|
|
```
