Responsive issue – Post "Comment" Page – day 2

Hello

As you can see in the attached photo, the post page is not centered under the header menu on the iPad. I gave the text left and right margins, so now the text shows, but the right side of the image border and the comments box is cut off still. Please find a solution to this. I hope there is some modification I can make to the code to fix this as it is really bothering me. Please help!
