@tailwindcss/aspect-ratio

A plugin that provides a composable API for giving elements a fixed aspect ratio.

Installation

Install the plugin from npm:

# Using npm
npm install @tailwindcss/aspect-ratio

# Using Yarn
yarn add @tailwindcss/aspect-ratio

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

// tailwind.config.js
module.exports = {
  theme: {
    // ...
  },
  plugins: [
    require('@tailwindcss/aspect-ratio'),
    // ...
  ],
}

Usage

Combine the aspect-w-{n} and aspect-h-{n} classes to specify the aspect ratio for an element:

<div class="aspect-w-16 aspect-h-9">
  <iframe src="https://www.youtube.com/embed/dQw4w9WgXcQ" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
</div>

Use aspect-none to remove any aspect ratio behavior:

<div class="aspect-w-16 aspect-h-9 lg:aspect-none">
  <!-- ... -->
</div>

Note that due to the way this currently needs to be implemented (the old padding-bottom trick) you need to assign the aspect ratio to a parent element, and make the actual element you are trying to size the only child of that parent.

Once the aspect-ratio property is supported in modern browsers, we'll add official support to Tailwind CSS itself and deprecate this plugin.

Aspect ratio classes up to 16 are generated by default:

Configuration

You can configure which values and variants are generated by this plugin under the aspectRatio key in your tailwind.config.js file:

// tailwind.config.js
module.exports = {
  theme: {
    aspectRatio: {
      1: '1',
      2: '2',
      3: '3',
      4: '4',
    }
  },
  variants: {
    aspectRatio: ['responsive', 'hover']
  }
}
