Lottery Number Generator

This project is a web application that generates random numbers for the UK National Lottery and (optionally) checks them against recent draws. The random number generator uses the Web Cryptography API to generate numbers in as non-deterministic a way as possible.

See the example: https://www.kirkbowe.com/lotto.html

• Share the generated numbers as an image on social media
• Responsive design for various screen sizes

Technologies Used

• HTML
• CSS
• JavaScript
• Bootstrap (CSS framework)
• html2canvas (JavaScript library for rendering HTML content as canvas)

Getting Started

To run the project locally, simply open the lotto.html file in a web browser.

Alternatively, you can host the project on a web server and access it through a URL.

Usage

1. Open the lotto.html file in a web browser.
2. Optionally, adjust the "Number of Balls" and "Highest Number" fields to customize the lottery number generation.
3. Check the "Fetch recent matches?" checkbox if you want to display recent matches from the last 180 days.
4. Click the "Generate" button to generate the random lottery numbers.
5. If the "Fetch recent matches?" option was selected, the best matches from the last 180 days will be displayed in a table.
6. To share the generated numbers as an image, click the "Share Image" button.
7. On narrow screens, the generated numbers will be scaled down to fit the viewport, and the circular backgrounds will maintain their proportions.
