Create a sudoku game that is just one HTML/CSS file.

Bash/sed

Once a general HTML file is generated, a bash script modifies the file for a given puzzle input. I don't really recommend this approach, but if you are learning bash then you can see some simple commands in action. I encourage you to try to make the script faster - there is plenty of room for improvement. I would certainly suggest not doing dozens of search and deletes

HTML

The index.html file is a generated file, so don't change it (any changes will be overwritten when you run script.js). Modify the template.html file.

CSS

A lot of CSS to run the game is included in the generated HTML file. Modify the style.css file to change the styling.

JavaScript

The script.js file generates the static file. You will need the nunjucks module and then just run node script.js to generate the index.html file.

It converts sudoku puzzle string into the game. The string is 81 characters. Nine characters for the first row from left to right, then nine for the second row, etc... Empty cells are represented by "."

You can modify the logic to accept different formats if needed.

This version of the script includes four not-necessary features that are nice to have. The numbers given from the start are bolded and should be impossible to erase. Any illegal moves (2 of the same number in a row, column, or 3x3 block) are blocked. Once all 9 of a given number have placed in the puzzle, that number in the selection bar at the top will be greyed out. Once the player has completed the puzzle, a message appears.
