Change color of your bubble app background beyond the top and bottom edges off your page.
This applies to some browsers, (like Chrome on Mac/iPhone, Safari/Firefox on iPhone).  For example, you could have a green header on your page or your page might have gray background color — since some browsers allow you to scroll beyond the top and bottom of the page, an awkward white background can show up beyond those edges.



Change vertical and horizontal scrollbars colors or make it transparent. Also you can scroll page using xy number without reference to element.

How to use:
1- Go to "Plugins" tab
2- Go to "Browser Fill" settings
3- Add color values as per your preferences for example: #FFDD00 or lightblue
