This method fetches an element with `selector`, scrolls it into view if needed, and then uses [Page.touchscreen](./puppeteer.page.touchscreen.md) to tap in the center of the element.
**Signature:**
```typescript
class Frame {
tap(selector: string): Promise<void>;
}
```
## Parameters
| Parameter | Type | Description |
| --------- | ------ | -------------------- |
| selector | string | the selector to tap. |
**Returns:**
Promise<void>
a promise that resolves when the element has been tapped.
## Remarks
If there's no element matching `selector`, the method throws an error.
