I have been playing around with many flat file CMSs - Baun, Phile and Pico to mention a few. I like the idea of TWIG templates and crisp, clear markdown along with the concept of using meta data in the .md file to provide instructions to the Twig template. My initial thought was that I could combine these capabilities in a powerful way with a CSS3 framework such as Bulma to create crisp, clean, modern web pages. Howver, there is consistently the same issue - as far as I can tell you can define only one content block in a markdown file. To apply varying styling to different parts of the content you need to dip down into HTML which I can do but I cannot really expect my content developers to do. Is there a simple flatfile CMS that does allow multiple content blocks in markdown.
For the benefit of anybody who runs into this question. I have now evaluated many flatfile CMS alternatives. The clear winner is Grav. With Grav you can create multiple content blocks, embed sub pages etc.
