tailwind-attributes-selectors

Tailwind plugin for creating custom attributes selectors

Installation

Install the plugin from npm:

npm install tailwind-attributes-selectors

Then add the plugin to your tailwind.config.js file:

// tailwind.config.js
const config = {
  "role-dialog": ["role", "=", "dialog"],       // matches [role="dialog"]  - an element with the role attribute set to "dialog"
  "is-external-link": ["href", "^=", "http"],   // matches [href^="http"]   - an element with the href attribute starting with "http"
  "has-role": "role",                           // matches [role]           - an element with the role attribute set
}

module.exports = {
  theme: {
    // ...
  },
  plugins: [
    require("tailwind-attributes-selectors")(config),
    // ...
  ],
}

Or with the shorthand version (typesafe with IntelliSense):

// tailwind.config.js
module.exports = {
  theme: {
    // ...
  },
  plugins: [
    require("tailwind-attributes-selectors")({
      "role-dialog": ["role", "=", "dialog"],
      "is-external-link": ["href", "^=", "http"],
      "has-role": "role",
    }),
    // ...
  ],
}

Usage

Possible matcher values are those you can use in normal css and are:

• "=": equals
• "~=": contains
• "|=": starts with (note: value has to be a whole word, either alone, like lang="en", or followed by a hyphen, like lang="en-US")
• "^=": starts with (note: value can be anything)
• "$=": ends with
• "*=": contains

In your template you can use any of the keys of the config object as classes, for example (with the above config):

<div role="dialog" class="role-dialog:background-white">...</div>
<a href="https://example.com" class="is-external-link:background-white">...</a>
<div role="whatever" class="has-role:background-white">...</div>

This can became useful when working with components when you don't know which attributes will be passed to a certain component
