My posts have no taxonomy or share the same date.
For each post (
layouts/post/single.html), I would like to display the previous three posts.
posts |---post-1 |---post-2 |---post-3 |---post-4 |---post-5
When visiting post-5, I would like to display links to post-4, post-3, and post-2.
When visiting post-4, I would like to display links to post-3, post-2 and post-1.
How do I approach this?
