How to put a cordova barcode scanner inside a fixed div

In my meteor, I need to implement a qr code scanner. I am trying to use cordova barcode scanner package for meteor. The scanner is running fine on the android phone. But my requirement is to put this scanner inside a fixed div, so that other actions can also be kept to perform other functions.

For example, at the top right corner in the screen, there will be a cancel button, and below that there will be an header with some text, and below that should be placed the scanner.

This whole thing will be inside a template. The problem is that when I am trying to implement this, the scanner is occupying the entire screen. I need help to achieve this goal, I have searched many forums but could not found something useful to meet my requirements.

Any help would be greatly appreciated.
