Styles generated by this plugin are only used if the `mode-dark` class is applied to the `<html>` element. How you do that is up to you. `dark-mode.js` is provided as an option, which is a simple script that enables dark mode from 6 PM to 6 AM in the user's timezone.

To modify the default class name, pass a configuration object to the plugin:

```javascript
plugins: [
require('tailwindcss-dark-mode')({
darkModeClassName: 'dark-mode-enabled',
})
]
```

### Available Variants

Variants for dark mode are based on [Tailwind's own variants](https://tailwindcss.com/docs/state-variants/)...
