If this is too much off topic feel free to move my questions to a new topic.
What then is good and future proof shortcode style—particularly for shortcodes you may intend to publish in a theme:
- Always use
{{%
—unless you really do not want any markdown rendered to HTML? (As an example the cupper theme uses{{% codePen VpVNKW %}}
.) - Always use
{{< />}}
—if required withmarkdownify
—and only use{{%
if there is markdown in the shortcode html file itself?
