How to get question body (markdown) in the API response using filters? [duplicate]

Question

Using withbody filter as suggested in this thread (How to get Question/Answer body in the API response using filters?) returns body as HTML. How do I get the original markdown?

Answer 1

The body_markdown field in the question (or answer) categories will give you the markdown.

So, !9YdnSJ*_T would be the filter to get a question with the markdown.

What's the proper way of doing this without causing any issues with different screen sizes? I assume this a common requirement, but I haven't yet seen a good code sample. A key requirement other than having acceptable display on all screen sizes is the menu collapsibility on smaller screens.\r\n\r\nI tried just putting an IMG tag inside the A tag that has the navbar-brand class, but that caused the menu not to function properly on my android phone. I also tried increasing the height of the navbar class, but that screwed things up even more.\r\n\r\nBy the way, my logo image is larger than the height of the navbar.",
