Here's a basic implementation for the `index.html` file, which serves as the main HTML file for your static shopping list application:
```html
Shopping List
Shopping List
```
### Key Components:
- **Input Field**: Users can type the name of the item they wish to add to the shopping list.
- **Add Item Button**: Clicking this button will trigger a JavaScript function to add the item to the list.
- **Unordered List (`
`)**: This is where the shopping list items will be dynamically added and displayed.
- **Link to CSS**: Includes a link to `styles.css` for styling purposes.
- **Script Inclusion**: Includes the `app.js` file, where the JavaScript logic for adding and removing items will be implemented.
