`post:after` should work if you want to add new elements to the bottom of a post. Note that you have a space between `post:` and `after`.

I think this is related to what you’re trying to do.

> Posts are [widgets](https://meta.discourse.org/t/a-tour-of-how-the-widget-virtual-dom-code-in-discourse-works/40347) which means what you’re trying to do will involve a bit more work that just adding html. Discourse themes have the ability to [decorate widgets](https://meta.discourse.org/t/developer-s-guide-to-discourse-themes/93648#heading--4-c-6) so you can leverage on that. Decorating a widget is explained in the link above so let’s focus on what you’re trying to do - add markup after the first post in every topic. Start by adding the markup to all posts. So something like this \<script type="text/discourse-plugin" version="0.8"\> api.decorateWidget("post:after", helper =\> { …

If you still have problems, then please post the rest of the code you’re using.
