Tailwind CSS checkbox styles are not working

Question

I have a checkbox in my Next.js project and after adding some Tailwind utility classes nothing takes effect except changes to width, height and cursor. Color, bg, border, etc. don't work.

        <div className="flex py-4 m-auto w-2/3 justify-between items-start">
          <div className="w-1/7">
            <div className="border-b pb-4">
              <h1 className="mb-2 font-medium">Filter 1</h1>
              <label htmlFor="c1">
                <div className="flex group active:ring-2 ring-black rounded">
                  <input
                    id="c1"
                    type="checkbox"
                    className="rounded-full h-8 w-8 cursor-pointer bg-red-100 border-red-300 text-red-600 focus:ring-red-200"
                  />
                  <p className="pl-2 text-reg cursor-pointer group-hover:underline decoration-solid">
                    Subfilter 1
                  </p>
                </div>
              </label>
            </div>
          </div>
        </div>

cursor-pointer, h-8 and w-8 are the only utility classes that are working in the checkbox. color still defaults to blue, there's no ring appearing on focus, and bg still white.

Others elements in the example code like p, div and h1 are working perfectly.

Add tailwindcss/forms to your config file:

module.exports = {
  theme: {
    extend: {
      // ...
    },
  },
  plugins: [require("@tailwindcss/forms")],
};

You can read more about it in the docs and the GitHub repository.

Here is a working example in Tailwind Play.
