[Migration from Jekyll] Best approach to provide custom templates for a blog post project

[adithyabsk]

Hello!

I'm migrating from fastpages, and I've hit a snag. I had a custom template in Jekyll that would let me automatically redirect to external blog posts using a meta refresh tag.

I've been digging into both the docs and reference page in quarto and cannot for the life of me figure out how to:

1. configure a template for a particular page to use
2. pass variables to said template

I have been able to pass html snippets to the default quarto template by setting include-after-body in a _metadata.yml file. A similar approach using include-in-header was working, but the page was too heavy and the meta refresh took too long.

Was looking for some ideas on how other folks implemented something similar.
