Some Website Post Not Responsive in IE and mobile.

A nice day to you, I hope you can help with my website viewing.
Issue: Some of the post are not showing as responsive in IE and mobile. The post are all while, and looking like it is in a frame - there is no navigation to other pages or the main page. It just has a previous and next button.

Hopefully you can recreate the issue and assist, this does not happen with every post, just random ones.
