        ]

OR

npm i -D postcss-elm-tailwind

### Other output formats

#### SVG

If you want to use Tailwind classes to style `SVG` you can output an `Svg` module like this:

```js
module.exports = {
  plugins: [
    require("tailwindcss"),
    require("postcss-elm-tailwind")({
      tailwindConfig: "./tailwind.config.js",
      elmFile: "src/Tailwind.elm",
      elmModuleName: "Tailwind",
      formats: {
        svg: {
          elmFile: "src/Tailwind/Svg.elm",
          elmModuleName: "Tailwind.Svg"
        }
      }
    })
  ]
};

String

If you want access to the class names themselves, you can output a String module as an escape hatch:

module.exports = {
  plugins: [
    require("tailwindcss"),
    require("postcss-elm-tailwind")({
      tailwindConfig: "./tailwind.config.js",
      elmFile: "src/Tailwind.elm",
      elmModuleName: "Tailwind",
      formats: {
        string: {
          elmFile: "src/Tailwind/String.elm",
          elmModuleName: "Tailwind.String"
        }
      }
    })
  ]
};

Other things to note

In order to get a small build, you’ll need to build Tailwind twice - once without purgecss to build TW.elm with all the classes and once with purgecss so that all the unused classes are removed from your production CSS. See how this is implemented in the demo.
