This project, at times, is a little complicated. Based on my assumptions that I will not use the WordPress Classic Editor and will use Gutenberg and the Block editor, and the default theme, it has made it such that I can’t use a couple of the plugins that might have made this more straightforward. I also wanted to try to use the WordPress blocks to accomplish this.

I succeeded in replying to this post. To do so I used a combination of blocks and HTML in a Custom HTML block. Ideally, I would have been able to add a class to each block and avoid the HTML. But I think that this compromise is a practical solution.

I have placed the classes on groups (divs) and placed the posts URL and class in the custom HTML. Screenshot below.

The result was a reply that was posted to Mastodon with the assistance of https://brid.gy by Ryan Barrett. Ryan has answered a lot of questions along the way.

There are multiple resources that helped with finding out how to do this.

This was part of the plan but I was inspired today because of Tantek Çelik’s post on the six year anniversary of Webmentions.
