So, does the end span tag only works inside the tag it is commanded to be functional?

Answer 1

You are welcome,
Have I understand your question correctly?
Have you tried in code playground? What finding did you get?

Answer 2

I read again and again and I don't quite understand your question.

But if I must make a guess, your question is about the sequence of tags

Case I
<p> <span> content </span> </p>

Case ii
<p> <span> content </p> </span >

Case iii
</span><p><span> content </p>

Instead of telling you what is right and what is wrong, actually a better way is :
You can put them in code playground and experiment them 😉
