CSS

We are using tailwind. To set it up:

1. webpack needs a postcss-loader, which is added to webpack.config.cjs This parses through all the css and builds and AST to open up a bunch of plugins to interact with the css.
2. Because the postcss-loader, we need a postcss.config.cjs file to allow tailwind to parse through the css AST.
3. We also need tailwind.config.cjs to configure tailwind. Note that the content section is important because tailwind looks through all your HTML/JSX to extract all the classnames to generate only the css relevant to your usage.
