Creating a custom Tailwind plugin allows you to extend Tailwind's functionality with your own utility classes. This involves defining a plugin function that adds new utilities to Tailwind's core.

<!-- BEGIN COPY / PASTE -->
    const plugin = require('tailwindcss/plugin');

    module.exports = {
      plugins: [
        plugin(function({ addUtilities }) {
          const newUtilities = {
            '.text-shadow': {
              textShadow: '2px 2px 4px rgba(0, 0, 0, 0.1)',
            },
            '.text-shadow-md': {
              textShadow: '3px 3px 6px rgba(0, 0, 0, 0.1)',
            },
          };

          addUtilities(newUtilities, ['responsive', 'hover']);
        })
      ],
    };
    <!-- END COPY / PASTE -->

Additional Comment:

Use the "plugin" function from Tailwind to define your custom utilities.
The "addUtilities" function allows you to add new CSS rules, specifying variants like "responsive" or "hover".
Place this configuration in your "tailwind.config.js" file to integrate it with your Tailwind setup.
Ensure your custom utilities do not conflict with existing Tailwind classes.
