Consistent Issue: Invalid Tailwind CSS classnames order

Every time I save the file, the order of Tailwind CSS classnames are automatically changed, even when they are correct. Like, every time. And each save scrambles them in an incorrect order.

Here’s my .eslintrc:

{
  // Configuration for JavaScript files
  "extends": [
    "airbnb-base",
    "next/core-web-vitals", // Needed to avoid warning in next.js build: 'The Next.js plugin was not detected in your ESLint configuration'
    "plugin:prettier/recommended"
  ],
  "rules": {
    "prettier/prettier": [
      "error",
      {
        "singleQuote": true,
        "endOfLine": "auto"
      }
    ]
  },
  "overrides": [
    // Configuration for TypeScript files
    {
      "files": ["**/*.ts", "**/*.tsx"],
      "plugins": [
        "@typescript-eslint",

      },

          {
            "singleQuote": true,
            "endOfLine": "auto"
          }
        ],
        "react/destructuring-assignment": "off", // Vscode doesn't support automatically destructuring, it's a pain to add a new variable

          "warn",
          {
            "officialSorting": true
          }
        ], // Follow the same ordering as the official plugin `prettier-plugin-tailwindcss`
        "simple-import-sort/imports": "error", // Import configuration for `eslint-plugin-simple-import-sort`

        ]
      }
    },

    {
      "files": ["**/*.test.ts", "**/*.test.tsx"],
      "plugins": ["jest", "jest-formatting", "testing-library", "jest-dom"],
      "extends": [

        "plugin:jest-formatting/recommended",
        "plugin:testing-library/react",
        "plugin:jest-dom/recommended"
      ]
    }
  ]
}

@amunrarara Thank you for taking the time to share the correct response. It’ll help other in the same situation.

You likely using vscode with one vscode plugin that sort your css classes on save, that counters the order of the tailwind prettier plugin.

This was the correct answer. Thank you for looking into it, and sorry for the delay in response.
