TwentyEleven Theme on iPad

A child theme was created and I’m trying to put in the best CSS values for the Q&A plugin. It was easy for the TwentyTen themes but things are not working out for the TwentyEleven.

Can someone please take a look and let me know where I am going wrong.

It looks fine on a desktop browser but it looks horrible on the iPhone and iPad. There must be some CSS tweaks escaping me.
