### Adding Interactivity with JavaScript
To make the canvas interactive, use the Signature Pad library. This library enables users to draw on the canvas, clear it, undo strokes, and save their signatures as images.
**Event Handling:**
- **Clear Button**: Clears the canvas.
- **Undo Button**: Undoes the last stroke.
- **Save Buttons**: Saves the signature as PNG or JPEG.
- **Color Picker**: Changes the pen color.
### Hosting the HTML File
Once your HTML file is ready, upload it to your web hosting service. Ensure all resources, including the Signature Pad library, are correctly linked.
## SEO Best Practices
To improve the SEO of your Canvas Signature Pad page, follow these best practices:
1. **Title Tag**: Use a descriptive, keyword-rich title. Example: "How to Integrate a Canvas Signature Pad into Your Website".
2. **Meta Description**: Add a meta description summarizing the content.
3. **Headings**: Use proper heading tags (H1, H2, etc.) to structure your content.
4. **Alt Text for Images**: Provide descriptive alt text for any images you include.
5. **Internal and External Links**: Link to relevant internal pages and high-authority external sites.
