A small bug, any markdown code block notation is converted to single block views in the Markdown viewer. I compared the view inside DevonThink 3.0.2 versus Typora and other Markdown editors using the same .md file and same .css configuration file. If this .css is needed, I could provide it.
Please send a copy of the Markdown file and the stylesheet to cgrunenberg - at - devon-technologies.com. However, DEVONthink uses MultiMarkdown, therefore both the syntax and rendering are not necessarily like in external editors.
Thx sent the example. I think the issue is that fenced code blocks (```) are passed on as code (`) entities for presentation. This is standard Markdown.
