Pyro uses UnoCSS for styling, both internally and for user code. By default, the configuration that Pyro uses for UnoCSS looks something like:

import { presetUno } from "https://esm.sh/@unocss/preset-uno@0.58.0";

export default {
  presets: [
    presetUno({
      dark: "media",
    }),
  ],
};

Some users would prefer to have more UnoCSS features. This is supported with zero extra configuration outside of just making the file! At the top level of your site, just add a uno.config.ts file. Below is an example of configuring UnoCSS to add the presetTypography plugin. Make sure not to import from the main uno package, as that is unsupported.

// uno.config.ts
import { presetUno } from "https://esm.sh/@unocss/preset-uno@0.58.0";
import { presetTypography } from "https://esm.sh/@unocss/preset-typography@0.58.0";

export default {
  presets: [
    presetUno({
      dark: "media",
    }),
    presetTypography(),
  ],
};
