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:
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:
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:
## 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.

> Safely get a dot-notated path within a nested object, with ability to return a default if the full key path does not exist or the value is undefined
### Why?
Smallest possible implementation: only **130 bytes.**
You could write this yourself, but then you'd have to write [tests].
Supports ES Modules, CommonJS and globals.
### Installation
`npm install --save dlv`
### Usage
`delve(object, keypath, [default])`
```js
import delve from 'dlv';
let obj = {
a: {
b: {
c: 1,
d: undefined,
e: null
}
}
};
//use string dot notation for keys
delve(obj, 'a.b.c') === 1;
//or use an array key
delve(obj, ['a', 'b', 'c']) === 1;
delve(obj, 'a.b') === obj.a.b;
//returns undefined if the full key path does not exist and no default is specified
delve(obj, 'a.b.f') === undefined;
//optional third parameter for default if the full key in path is missing
delve(obj, 'a.b.f', 'foo') === 'foo';
//or if the key exists but the value is undefined
delve(obj, 'a.b.d', 'foo') === 'foo';
//Non-truthy defined values are still returned if they exist at the full keypath
delve(obj, 'a.b.e', 'foo') === null;
//undefined obj or key returns undefined, unless a default is supplied
delve(undefined, 'a.b.c') === undefined;
delve(undefined, 'a.b.c', 'foo') === 'foo';
delve(obj, undefined, 'foo') === 'foo';
```
### Setter Counterparts
- [dset](https://github.com/lukeed/dset) by [@lukeed](https://github.com/lukeed) is the spiritual "set" counterpart of `dlv` and very fast.
- [bury](https://github.com/kalmbach/bury) by [@kalmbach](https://github.com/kalmbach) does the opposite of `dlv` and is implemented in a very similar manner.
