# Page.setViewport() method
|
|
|
|
`page.setViewport` will resize the page. A lot of websites don't expect phones to change size, so you should set the viewport before navigating to the page.
|
|
|
|
In the case of multiple pages in a single browser, each page can have its own viewport size.
|
|
|
|
#### Signature:
|
|
|
|
```typescript
|
|
class Page {
|
|
abstract setViewport(viewport: Viewport): Promise<void>;
|
|
}
|
|
```
|
|
|
|
## Parameters

|
|
|
