div tags added for adsense not rendering properly in iphone/ipad

Hi, I created div tags to display google ads on left sidebar and on top (just below the header). Rendering is fine in desktop. But when I open my site in ipad/tablet/iphone/any smartphone, rendering is not proper. http://ladieskitty.net I need to resolve this issue urgently. Have been looking at css since morning and couldn't come up with a solution. One thing I know is that I need to put different versions of these div tags under all @media tags. PS: I have not created a child theme, which I am sure is going to be your first feedback. That of course is in pipe-line. Please help me resolve the issue at hand. Really appreciate your time and help. Thank you for creating such a fantastic theme. Regards Kanika
