## Page.focus() method
This method fetches an element with `selector` and focuses it. If there's no element matching `selector`, the method throws an error.
Signature:
```typescript
focus(selector: string): Promise;
```
## Parameters
| Parameter | Type | Description |
| --- | --- | --- |
| selector | string | A [selector](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Selectors) of an element to focus. If there are multiple elements satisfying the selector, the first will be focused. |
Returns:
