Platform Compatibility & Differences

GitHub (GFM):

GitHub renders frontmatter as an informational table at the top of markdown files.

Discord Chat:

Discord does not parse frontmatter; it displays as plain text with hyphens.

Reddit:

Not parsed on Reddit.

Jupyter Notebooks:

Not parsed in standard Jupyter (Jupyter uses cell metadata instead).

  1. Copy the ready-to-use YAML Frontmatter syntax snippet below.
  2. Inspect the rendered live preview in both light and dark themes.
  3. Review platform compatibility differences for GitHub, Discord, Reddit, and Jupyter notebooks.
  4. Check common pitfalls and copy formatted snippets directly.

Common Mistakes & Troubleshooting

  • Placing frontmatter anywhere other than line 1 of the file.
  • Using tabs instead of spaces for indentation in YAML keys.

Frequently Asked Questions

Must frontmatter always be at the very top of the file?

Yes! The opening `---` must be on line 1, column 1, with no blank lines or characters before it.
