<a id="function-getPageStyles">

### `getPageStyles() → Array<string | object>` _(internal)_

Harvests all web page styles, for instance, to allow re-using them in an `<iframe>` preserving the look of the content.

The returned data format is as follows:

```typescript
[
	'p { color: red; ... } h2 { font-size: 2em; ... } ...',
	'.spacing { padding: 1em; ... }; ...',
	'...',
	{ href: 'http://link.to.external.stylesheet' },
	{ href: '...' }
]
```

**Note**: For stylesheets with `href` different than window origin, an object is returned because accessing rules of these styles may cause CORS errors (depending on the configuration of the web page).

#### Returns

* `Array<string | object>`
