A views & CSS only solution for a previous post & next post buttons in a blog-node? I found the Previous/Next API module that lets you create previous-post &amp; next-post buttons, that you could put on any node.

For example, if you have nodes of the content type "Blog" you could put such two buttons under them in one div.

A core-only way would most likely include 2 view-blocks styled with some css (most probably display: flex; flex-wrap: wrap; etc).
This you can do easily with the Core Book module. As you can see on the any Drupal.org page for example, Drupal.org page.


  


Using Book module


You can create a Book which is like index and add the nodes in-order you want, and it will show Next and Prev as shown in above page as title of that node.
