Adding endnotes in a blog post

I would like to have endnotes in a blog post, where you can click on the number and be taken to the endnote; and then click on an arrow/other symbol and be taken back to your original spot in the post. See this post for an example - the links within the essay don't work, hence this post: 

https://www.speculativeinsight.com/essays/men-who-respect-witches-1

Can anyone suggest how I might make this work? 

You try this

The problem with this is that a code block can't be in the middle of a paragraph of text, as far as I can see - so I can have an anchor link to a heading, as I have now done: 

https://www.speculativeinsight.com/essays/men-who-respect-witches-1

... but I can't have a link to a specific footnote, nor can I have a link BACK to the text that you just left. Unless there is some way to do this in the middle of a text block?

Suppose you have a Text Block

You can split text to both Text Blocks, then add Code Block between both

But if the footnote needs to go at the end of a sentence, NOT the end of a paragraph, that doesn't solve the problem. Like this: 

The increasing gap between the rich and poor can lead, as The Spirit Level argues, to conflict and unrest.[1] The limited opportunities afforded to... 

I've managed to link the [1] to the bottom of the page, where the endnote is. I cannot, however, make the note at the bottom of the page link BACK to that text near the top of the page. 

An unfortunate work around might be to create a section styling the end notes how you want and then save that and drop it in each time you create a blog post.

Hi @Helloparkerg - as far as I can tell that doesn't help with the issue of sending people BACK to their place in the text? See what I mean here: https://www.speculativeinsight.com/essays/men-who-respect-witches-1 - I can send the reader to the bottom of the page, for the footnote text, but I don't know how to have a link at the end of the footnote text to send them back up the page, to the place they left. (Which is usually in the middle of a paragraph.)
