Thank you, Septian, but I don’t quite understand, or maybe I wasn’t clear.
To use your first (“most efficient”) option, in what file do I “manually move the post navigation to the top”? I want the post navigation to be at the top not only on Mobile, (and not only when looking at one post), but ALWAYS.
It looks as if some variation of your suggested code would do that (leaving out the parts that restrict it to “Mobile”. (I’m pretty new at all this….I don’t completely understand how all these files interact – but this exercise is helping me learn.)
Best, Martha
