+# @tailwindcss/aspect-ratio
+
+A plugin that provides a composable API for giving elements a fixed aspect ratio.
+
+
+## Installation
+
+Install the plugin from npm:
+
+```sh
+npm install -D @tailwindcss/aspect-ratio
+```
+
+Then add the plugin to your `tailwind.config.js` file, and disable the `aspectRatio` core plugin to avoid conflicts with the native `aspect-ratio` utilities included in Tailwind CSS v3.0:
+
+```js
+// tailwind.config.js
+module.exports = {
+  theme: {
+    // ...
+  },
+  corePlugins: {
+    aspectRatio: false,
+  },
+  plugins: [
+    require('@tailwindcss/aspect-ratio'),
+    // ...
+  ],
+}
+```
+
+## Usage
+
+Combine the `aspect-w-{n}` and `aspect-h-{n}` classes to specify the aspect ratio for an element:
+
+```html
+<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:
+
+```html
+<div class="aspect-w-16 aspect-h-9 lg:aspect-none">
+  <!-- ... -->
+</div>
+```
+
+When removing aspect ratio behavior, if nested elements have `w-{n}` or `h-{n}` classes, ensure they are re-declared with a matching breakpoint prefix:
+
+```html
+<div class="aspect-w-16 aspect-h-9 lg:aspect-none">
+  <img src="..." alt="..." class="w-full h-full object-center object-cover lg:w-full lg:h-full" />
+</div>
+```
+
+Note that due to the way this currently needs to be implemented ([the old padding-bottom trick](https://css-tricks.com/aspect-ratio-boxes/)) 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](https://developer.mozilla.org/en-US/docs/Web/CSS/aspect-ratio) 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:
+
+| Width | Height |
+| --- | --- |
+| `aspect-w-1` | `aspect-h-1` |
+| `aspect-w-2` | `aspect-h-2` |
+| `aspect-w-3` | `aspect-h-3` |
+| `aspect-w-4` | `aspect-h-4` |
+| `aspect-w-5` | `aspect-h-5` |
+| `aspect-w-6` | `aspect-h-6` |
+| `aspect-w-7` | `aspect-h-7` |
+| `aspect-w-8` | `aspect-h-8` |
+| `aspect-w-9` | `aspect-h-9` |
+| `aspect-w-10` | `aspect-h-10` |
+| `aspect-w-11` | `aspect-h-11` |
+| `aspect-w-12` | `aspect-h-12` |
+| `aspect-w-13` | `aspect-h-13` |
+| `aspect-w-14` | `aspect-h-14` |
+| `aspect-w-15` | `aspect-h-15` |
+| `aspect-w-16` | `aspect-h-16` |
+
+## Configuration
+
+You can configure which values and variants are generated by this plugin under the `aspectRatio` key in your `tailwind.config.js` file:
+
+```js
+// tailwind.config.js
+module.exports = {
+  theme: {
+    aspectRatio: {
+      1: '1',
+      2: '2',
+      3: '3',
+      4: '4',
+    }
+  },
+  variants: {
+    aspectRatio: ['responsive', 'hover']
+  }
+}
+```
+
+## Compatibility with default aspect-ratio utilities
+
+Tailwind CSS v3.0 shipped with [native aspect-ratio](https://tailwindcss.com/docs/aspect-ratio) support, and while these new utilities are great, the `aspect-ratio` property isn't supported in Safari 14, which still has [significant global usage](https://caniuse.com/mdn-css_properties_aspect-ratio). If you need to support Safari 14, this plugin is still the best way to do that.
+
+While it's technically possible to use the new native `aspect-ratio` utilities as well as this plugin in the same project, it doesn't really make a lot of sense to do so. If you're able to use the new native aspect-ratio utilities, just use them instead of this plugin, as they are a lot simpler and work much better.
+
+However, if you do want to use both approaches in your project, maybe as a way of transitioning slowly from the plugin approach to the new native utilities, you'll need to add the following values to your `tailwind.config.js` file:
+
+```js
+module.exports = {
+  // ...
+  theme: {
+    aspectRatio: {
+      auto: 'auto',
+      square: '1 / 1',
+      video: '16 / 9',
+      1: '1',
+      2: '2',
+      3: '3',
+      4: '4',
+      5: '5',
+      6: '6',
+      7: '7',
+      8: '8',
+      9: '9',
+      10: '10',
+      11: '11',
+      12: '12',
+      13: '13',
+      14: '14',
+      15: '15',
+      16: '16',
+    },
+  },
+}
+```
+
+This is necessary, as the default `aspectRatio` values are overwritten by this plugin's values.
