Empty box on last post

[berat]

There is a simple problem with the box that links to previous/next articles in a blog post. If we are in the last post, the next post box is empty, if we are in the first post, the previous post box is empty. I am not a designer, but if there is no previous/next post here, if we make the width of the other box 100%, maybe we can fill the gap here.

If there is any request or design file, I would be happy to develop it.
