Usage

Specify an element’s transform origin using the origin-{keyword} utilities.

<img class="origin-center transform rotate-45 ..."> <img class="origin-top-left transform rotate-45 ..."> <img class="origin-bottom-right transform rotate-45 ..."> <img class="origin-left transform rotate-45 ...">

Responsive

To control the transform-origin of an element at a specific breakpoint, add a {screen}: prefix to any existing transform-origin utility. For example, use md:origin-top to apply the origin-top utility at only medium screen sizes and above.

<img class="origin-center md:origin-top ...">

Customizing

Origin values

By default, Tailwind provides transform-origin utilities for all of the built-in browser keyword options. You change, add, or remove these by customizing the transformOrigin section of your Tailwind theme config.

  // tailwind.config.js   module.exports = {   theme: {   extend: {   transformOrigin: { + '24': '6rem', + 'full': '100%',   }   }   }   }

Learn more about customizing the default theme in the theme customization documentation.

Variants

By default, only responsive variants are generated for transform-origin utilities.

You can control which variants are generated for the transform-origin utilities by modifying the transformOrigin property in the variants section of your tailwind.config.js file.

For example, this config will also generate hover and focus variants:

 // tailwind.config.js  module.exports = {   variants: {   extend: {  // ... +  transformOrigin: ['hover', 'focus'],   }   }  }

Disabling

If you don't plan to use the transform-origin utilities in your project, you can disable them entirely by setting the transformOrigin property to false in the corePlugins section of your config file:

 // tailwind.config.js  module.exports = {   corePlugins: {  // ... +  transformOrigin: false,   }  }
