Figured it out. Here is the whole code that is working now.
Tiggzi('mobilecontainer1').css('background-image','url("' + Tiggzi.getImagePath('Poster_Background_Only_1024_Light.jpg') + '")');
Tiggzi('mobilecontainer1').css('background-repeat','no-repeat');
Tiggzi('mobilecontainer1').css('background-size','cover');
Hello! Thank you for sharing code
My background image doesn't adapt to the different screens.
I load this code:
$('div[dsid="mobilecontainer1"]').css('background-image',
'url("https://dl.dropboxusercontent.com/u/1...")')
$('div[dsid="mobilecontainer1"]').css('background-size','cover');
but I get this result. 
How do i re-size a background image to fit the screen?

When I try to cover the entire screen with my background image it gets cut off on larger screen sizes. Like this... 
How do I get the image to proportionally resize to every screen size? The image I am using is 970 px x 970 px so it should be large enough no matter what screen size.
