How to change viewing settings?

On laptops and computers via a Chrome browser:

1. Use the zoom in and out buttons
2. Click “page layout” to switch between 1 and 2 page view or to rotate the page  

On iPads, iPhones and Android tablets and smartphones:

1. Use two fingers to zoom in and out, like you do with photos
2. Pinch the screen to return to full page view
3. You can also use the app in landscape mode (make sure that screen rotation is enabled in your device’s settings)
