Raw HTML & Front Matter

tags: [markdown, docs]

<!-- Front matter (YAML between --- delimiters) is a static-site-generator
     convention (Jekyll, Hugo, etc.), not part of core Markdown/CommonMark.
     It's parsed separately from the body content below it. -->

Most renderers pass raw HTML through untouched for anything Markdown's
syntax doesn't cover:

<details>
<summary>Click to expand</summary>

Hidden content here — Markdown syntax still works INSIDE the HTML block.

CommonMark & Renderer Differences

The original Markdown spec left several edge cases ambiguous, so implementations (GitHub, Markdown.pl, various editors) diverged over time. CommonMark was created as a strict, unambiguous specification to reduce this fragmentation — GitHub Flavored Markdown (GFM, which adds tables, task lists, strikethrough, and autolinks) is built on top of CommonMark. If a document renders differently across two tools, it's often a genuine historical spec ambiguity rather than a bug.
