I moved from Jekyll to Zola and it's been great until I started tinkering with templates and stuff recently. Single binary and simple themes were main reasons to choose this. Wanted a feature that wasn't present in the version I started with (about 2 years ago). So, I got the newest version and a few things broke subtly (ex: syntax highlighting). Which led me to tinkering (I don't know much about HTML/CSS/etc).
It was actually good to try a few things almost blindly and then slowly narrowing with a bit more thought process. Been a long time since I had such fun investigating unknown codebase. This even helped me move my post processing scripts to templates. And then I went a step further by reading about meta tags (things like image, description, etc) and adding them via an extra variable in the post frontmatter.
