Advantages

1. options for defining your separator, and brackets
2. support for nested variants
3. There is a postCSS plugin to support css files
4. support for Vite

Reference

• Why are other similar plugins not suitable for me?
• Installation

Demonstration

jsx

Example 1 { separator = "," }:

One of the proposed syntaxes in X, which is voted for the most

Before:

const Main = () => {
	return <main className="flex mm:bg-red,text-green,hover:text-3xl">...</main>;
};

After:

const Main = () => {
	return <main className="flex mm:bg-red mm:text-green mm:hover:text-3xl ">...</main>;
};

Example 2 { separator = ",", opBracket = "(", clBracket = ")" }:

const main = () => {
  return <main className="flex supports-[not(**)]:min-height-[10.1px]:h-10,sm:h-20,md:h-30, lg:h-40,xl:h-50,hover:(pl-4,py-3) pl-3">...</main>;};

After:

const main = () => {
        return <main className="flex supports-[not(**)]:min-height-[10.1px]:h-10 supports-[not(**)]:min-height-[10.1px]:sm:h-20 supports-[not(**)]:min-height-[10.1px]:md:h-30 supports-[not(**)]:min-height-[10.1px]:lg:h-40 supports-[not(**)]:min-height-[10.1px]:xl:h-50 supports-[not(**)]:min-height-[10.1px]:hover:pl-4 supports-[not(**)]:min-height-[10.1px]:hover:py-3 pl-3">...</main>;};

css

IMPORTANT: You need to connect the PostCSS plugin

Before:

.class {
	@apply mm:bg-red,text-green;
}

After:

.class {
	@apply mm:bg-red mm:text-green;
}

Remark

1. Using SPACE for separator will result in an error. This is done for several reasons:

• more precisely in prettier-plugin-tailwindcss
• One of the posts in X by the creator of tailwindcss, talked about how incompatible this syntax is with different templates (like unoCSS)

2. The problem with auto-completion (is not displayed) (tailwindcss intelliSense) (you can solve it in the settings using: "tailwindCSS.experimental.classRegex")
3. Strange formatting of user classes - puts all classes at the beginning. But as I realized, this problem is solved https://github.com/tailwindlabs/prettier-plugin-tailwindcss/issues/228

Installation

• Webpack/next.js
• PostCSS
• Vite

Webpack/next.js

npm install --save-dev tailwindcss-multiple-classes

Creating a function and exporting it:

// transformMultipleClasses.js
import createTransform from 'tailwindcss-multiple-classes';

const transformMultipleClasses = createTransform({ separator: ',', opBracket: '(', clBracket: ')' });

export default transformMultipleClasses;

  webpack: (config, options) => {
    config.module.rules.push({
      test: /\.jsx/,
      use: path.resolve('./transformMultipleClasses.js'),
    });

    return config;
  },

IMPORTANT: use javascript to support webpack IMPORTANT: Often, everything ends with the conversion of files, but if you have any problems, try to use this:

Adding to the tailwindcss configuration:

//tailwindcss.config.js
import transformMultipleClasses from './src/transformMultipleClasses.js';

const config = {
  content: {
    files: ['./src/**/*.{js,ts,jsx,tsx,mdx}'],
    transform: {
      jsx: (content = '') => transformMultipleClasses(content),
      // You can designate for any file extension
    },
  }

  ...
}

IMPORTANT: This setting is necessary for tailwindcss to understand what classes it needs to generate in a CSS file, but it does not work as a compiler for files. Details: https://github.com/tailwindlabs/tailwindcss/issues/13705#event-12857014225 IMPORTANT: You may need it for Vite/Rollup, but if it works without it, then you don't need it

PostCSS

https://www.npmjs.com/package/postcss-tailwindcss-multiple-classes

Vite/Rollup

https://www.npmjs.com/package/rollup-plugin-tailwindcss-multiple-classes

Support Vite / Rollup

npm install --save-dev rollup-plugin-tailwindcss-multiple-classes

IMPORTANT: I advise you to install the plugin itself and the plugin for PostCSS for vite. If there is any error, install content.transform (in the installation section in webpack/next.js )

// vite.config.js
import tailwindMultipleClasses from "rollup-plugin-tailwindcss-multiple-classes";

export default defineConfig({
	plugins: [tailwindMultipleClasses({ separator: ",", opBracket: "(", clBracket: ")" }), react()],
});

IMPORTANT: This plugin ignores all files in node_modules, as well as all CSS files and its derivatives. PostCSS is used for this IMPORTANT: If you have any problems, try to rearrange this plugin and the 'react` plugin
