Thank you! This is so helpful. The construction of how the blocks fit together on the posts (home) page is what I was stuck on. I really appreciate your attention. I did get it to work. Many, many thanks!
Thanks for the quick & helpful reply. This is on the posts page, not a single post. Would I need to add a query loop?
Thanks, I actually found a non-code fix. I went to Menu Theme > Mobile Menu > enabled Sub Menu – Force Full Width. That fixed it.
