Content/FolderName/_index.md use requires the below change to list.html.
I created a folder in /content/ and used the _index.md to display content in that folder. The theme required adding the below to list.html Line 13 start:
<div class="row pb-5">
<div class="col-12 d-flex justify-content-center">
<div class="blog-content fs-5">
{{ .Content }}
</div>
</div>
</div>
So that the content in _index.md would be displayed.
Thanks for the theme!!!
