Use the jinja2 templating to generate the index.html file from template.html. The syntax is similar to nunjucks.
A template file called template.html is used to eventually create the index.html file with the final game.
A lot of the CSS is generated automatically, but the style.css file can be modified like normal CSS to change the appearance of the page.
