tailwind-next

A TailwindCSS Plugin that lets you target subsequent-sibling or "next" element.

<div>
  <input type="checkbox" class="next-p:checked:bg-blue-500 next-h2:checked:bg-red-500">
  <p>
    Next Element
  </p>
  <h2>
    Another Element
  </h2>
<div>

Generates this CSS which gives p element or any other element that is next in line to the selector one "bg-red-500":

.next-h2\:checked\:bg-red-500:checked ~ h2 {
  --tw-bg-opacity: 1;
  background-color: rgb(239 68 68 / var(--tw-bg-opacity));
}
.next-p\:checked\:bg-blue-500:checked ~ p {
  --tw-bg-opacity: 1;
  background-color: rgb(59 130 246 / var(--tw-bg-opacity));
}

Expandable using theme/extend

module.exports = {
  content: [],
  theme: {
    extend: {
      nextTags: {
        custom: 'custom',
        ".selector": ".selector",
      },
    },
  },
  plugins: [],
}

You can even use custom class/ID selectors like .selector in example above. Which will generate:

.next-someEl\:bg-black ~ custom {
  --tw-bg-opacity: 1;
  background-color: rgb(0 0 0 / var(--tw-bg-opacity));
}

.next-\.selector\:bg-purple-500 ~ .selector {
  --tw-bg-opacity: 1;
  background-color: rgb(168 85 247 / var(--tw-bg-opacity));
}

The order of Variants when writing a class can be a bit weird but currently TW Compiles it in a "reverse" way so it is what it is... for now.
