SyntaxError: Unexpected token, expected ";" for .css files using Prettier

Question

I am trying to use Prettier with eslint and TypeScript. When I am running npm run prettier -- --list-different all of my css files are getting the error SyntaxError: Unexpected token, expected ";". I am thinking it is an issue with the way I have my parsing set up, but cannot seem to get it to work. This is my current setup.

.eslintrc

{
  "parser": "@typescript-eslint/parser",
  "parserOptions": {
    "ecmaVersion": 2018,
    "sourceType":  "module",
    "ecmaFeatures":  {
      "jsx":  true
    }
  },
  "extends": [
      "plugin:@typescript-eslint/recommended",
      "plugin:react/recommended",
      "prettier/@typescript-eslint",
      "plugin:prettier/recommended"
  ],
  "rules": {
    "no-console": "warn",
    "@typescript-eslint/explicit-function-return-type": ["warn", {"allowExpressions": true}]
  },
  "settings": {
      "react" : {
        "createClass": "createReactClass",
        "pragma": "React",
        "version":  "detect"
      }
  },
  "env": {
    "browser": true
  }
}

.prettierrc

{
  "arrowParens": "avoid",
  "bracketSpacing": true,
  "htmlWhitespaceSensitivity": "css",
  "insertPragma": false,
  "jsxBracketSameLine": false,
  "jsxSingleQuote": false,
    "parser": "babel",
    "printWidth": 120,
    "proseWrap": "always",
    "requirePragma": false,
    "semi": true,
    "singleQuote": true,
    "tabWidth": 2,
    "trailingComma": "none",
    "useTabs": false        
}

css file

body {
  margin: 0;
  padding: 0;
  font-family: sans-serif;
}

package.json (just in case)

{
  "name": "my-app",
  "version": "0.1.0",

  },
  "browserslist": [
    ">0.2%",
    "not dead",
    "not ie <= 11",
    "not op_mini all"
  ]
}

I have tried adding overrides to the .prettierrc and .eslintrc files like this but it did not work.

"overrides": [{
    "files": "*.css",
    "options": {
        "parser": "babel"
     }
}]

.eslintignore file was helpful: stackoverflow.com/a/64931551/470749 — Ryan

Turns out I needed to add the overrides to the .prettierrc file with the parser set to css. I was using the wrong parser, trying things like postcss-scss instead. It would look like this.

"overrides": [
  {
    "files": "*.css",
    "options": {
      "parser": "css"
    }
  }
]

Documentation is here: https://prettier.io/docs/en/options.html#parser
