Thank you so much. I have given the next-post column block a name and then added the following in my CSS

.wp-post-nav-next-column-block {text-align: right;}

And bingo. I have a lovely right aligned next-post button. Big smiles!

So further to this. I am still experiencing the frustration of not being able to right align my right hand navigation button.

Further to my previous post on the subject, I am using the Gutenberg editor and I have the shortcode inside columns, inside a group which also includes the post content.

It looks to me that the flexbox is causing me problems but I might be wrong?

Brilliant! Thanks for your prompt reply.
