Editor for Jekyll Content

I’m not a Jekyll user.
I answered in a similar topic today, where I stated what I use.

What I do is prioritize my readers, so my editor in Obsidian can look like a mess but it’s fine if the rendered content online reflects my intentions. So you can type in whatever template format you need – which will do nothing in Obsidian – but once out online, it will do something for you. What I do is %%comment out%% what I don’t want to be seen online – I can do that with the Digital Garden I use. Not knowledgeable about your template’s powers.
