How can I align background image on a specific side. (Especially on mobile device) / IronTemplates

WPBakery doesnt have the option to align background as we want but we can add one of those extra class in the "extra class name" field to customize the background position.

bg-left-top
bg-left-center
bg-left-bottom
bg-right-top
bg-right-center
bg-right-bottom
bg-center-top
bg-center-center
bg-center-bottom
