Help with CSS to make Q&A responsive

I added these additional CSS rules to Q&A settings (Ari suggested them in an older thread) I also made width inputs in the settings area blank.

#question-form textarea.wp32, #answer-form textarea.wp32{width: 99% !important;}

This makes the Q&A area http://acnemantra.com/questions "somewhat" responsive.

The question titles are still not wrapping around fully on my phone.

The sidebar overlaps the whole Q&A area and just makes everything messy.

I'd like the sidebar area to wrap to the bottom of the Q&A section on smaller screens.

My theme is fully responsive and I cannot afford the Q&A section to not be so too. Please help!!

Thanks!
