# 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
class Page {
focus(selector: string): Promise<void>;
}
```
## 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:**
Promise&lt;void&gt;
Promise which resolves when the element matching selector is successfully focused. The promise will be rejected if there is no element matching selector.
## Remarks
Shortcut for [page.mainFrame().focus(selector)](./puppeteer.frame.focus.md).
