Formatting

Front matter

YAML document properties and all eight presentation modes.

Recognized input

Front matter must begin on the first line with an exact ---, end with an exact ---, and contain a YAML property mapping. source disables extraction. A later horizontal rule does not start front matter.

Configuration and styling

Save the mode in front_matter. Theme fields front_matter.title, key, value and border control the properties panel. --from selects a range of the Markdown body after front matter extraction; source line numbers retain their original positions.
