hi, i’d like to use [GitHub - alanorth/hugo-theme-bootstrap4-blog: A blogging-centric Bootstrap v4 theme for the Hugo static site generator.](https://github.com/alanorth/hugo-theme-bootstrap4-blog) as theme, but i need some special .css included in all posts/entry page etc., so i found this [Add ability to insert custom code into the global \<head\>. by DeedleFake · Pull Request #17 · alanorth/hugo-theme-bootstrap4-blog · GitHub](https://github.com/alanorth/hugo-theme-bootstrap4-blog/pull/17) but somehow, it is not working.

> The change is pretty simple. I wanted to put some custom JavaScript in the of a site I’m building, but I didn’t want to have to edit the theme or make a copy of `layouts/_default/baseof.html` , since later changes to the theme may break it. This change allows code to be insterted into by creating a `layouts/partial/head-custom.html` .

i created a layouts/partial/head-custom.html, but it is not included. I echoed “TEST” in it, but its not included. What am i doing wrong?
