Children Variant Plugin for Tailwind CSS

Requirements

This plugin requires Tailwind CSS 1.2 or later. If your project uses an older version of Tailwind, you should install the latest 1.x version of this plugin (npm install tailwindcss-children@1.x).

Installation

npm install tailwindcss-children

Usage

// tailwind.config.js
module.exports = {
  variants: {
    display: ['children', 'default', 'children-first', 'children-last', 'children-odd', 'children-even', 'children-not-first', 'children-not-last', 'children-hover', 'hover', 'children-focus', 'focus', 'children-focus-within', 'focus-within', 'children-active', 'active', 'children-visited', 'visited', 'children-disabled', 'disabled', 'responsive'],
  },
  plugins: [
    require('tailwindcss-children'),
  ],
};

The above configuration would generate the following CSS:

.children\:block > * {
  display: block;
}

.block {
  display: block;
}

.children\:first\:block > :first-child {
  display: block;
}

.children\:last\:block > :last-child {
  display: block;
}

.children\:odd\:block > :nth-child(odd) {
  display: block;
}

.children\:even\:block > :nth-child(even) {
  display: block;
}

.children\:not-first\:block > :not(:first-child) {
  display: block;
}

.children\:not-last\:block > :not(:last-child) {
  display: block;
}

.children\:hover\:block > :hover {
  display: block;
}

.hover\:block:hover {
  display: block;
}

.children\:focus\:block > :focus {
  display: block;
}

.focus\:block:focus {
  display: block;
}

.children\:focus-within\:block > :focus-within {
  display: block;
}

.focus-within\:block:focus-within {
  display: block;
}

.children\:active\:block > :active {
  display: block;
}

.active\:block:active {
  display: block;
}

.children\:visited\:block > :visited {
  display: block;
}

.visited\:block:visited {
  display: block;
}

.children\:disabled\:block > :disabled {
  display: block;
}

.disabled\:block:disabled {
  display: block;
}

/* etc. */

Which you can then use in your HTML like this:

<ul class="children:block children:not-first:border-t children:border-gray children:hover:bg-gray">
  <li>
    First item
  </li>
  <li>
    Second item
  </li>
  <li>
    Last item, this one doesn't have a bottom border
  </li>
</ul>

You can also override children: classes on specific children if needed:

<ul class="children:block children:bg-gray">
  <li>
    First item
  </li>
  <li class="bg-red">
    Second item, this one has a red background
  </li>
  <li class="bg-blue">
    Third item, this one has a blue background
  </li>
  <li>
    Last item
  </li>
</ul>

The above depends on the order of the generated CSS, so make sure to add the default variant after the children one in the array of variants (as well as the hover variant after the children-hover variant if you want to override a children:hover:* utility, etc.).
