tailwindcss-z-index-map

tailwindcss-z-index-map is currently only tested with v3 of TailwindCSS.

A plugin for TailwindCSS that grants the ability to configure a set of z-map utility classes that remove the need for magical z-index numbers. Instead, define an array of classes in your Tailwind config in order from smaller z-index to larger.

Installation

Install the plugin from npm.

# Using npm
npm install tailwindcss-z-index-map

# Using yarn
yarn add tailwindcss-z-index-map

Then add the plugin to your tailwind.config.js file. Define your z-index map in the theme object.

// tailwind.config.js
module.exports = {
  theme: {
    zIndexMap: ["lowest-item", "middle-item", "highest-item"],
  },
  plugins: [require("tailwidcss-z-index-map")],
};

This will result in the following utility classes being generated:

.z-map-lowest-item {
  z-index: 1;
}

.z-map-middle-item {
  z-index: 2;
}

.z-map-highest-item {
  z-index: 3;
}

If you were to add another item in the middle of the map in the future, .z-map-highest-item would increase to a z-index of 4.
