Header Right Side Bar Float Left on Mobile?

Hello, I am wondering if it is possible to have the contents (e.g., images and text) of the header right sidebar text widget to float left on mobile devices. Right now they line up to the right which looks great on a normal computer screen, but not so good on the iphone. Website is not active yet. I will have to set up an admin account for you by email if you need to view it. Thanks in advance for your help. Josh
