Built-in Default Elements

Even without custom configuration, markdown-it-extensible ships with a comprehensive set of default elements designed for scholarly and structured work.

Default Block Containers

The following block containers are available out of the box:

Consolidated Core Minimal-Set (v2)

• grammar-box: Normative grammar rules, phonetic laws, and inflection paradigms.
• warning-box: Didactic warnings, language interference, and translation pitfalls.
• verse-box: Ślokas, mantras, sacred reading texts, and poetic meters.
• note-box: Scholarly notes, cultural background, sources, and literature references.
• indent: Structured indentation for citations, forms, and sub-derivations.
• media: Unified wrapper for images, captions, and licensing credits.
• no-header: Utility container to hide the table header (thead) for purely tabular data.

Graceful Aliasing for Legacy Containers (Backwards Compatibility)

• important → renders as warning-box
• literatur-box / literatur → renders as note-box
• compact → renders as verse-box
• metrik-schema, center, laut-table, deleteme-box (legacy containers remain functional)

Scholarly & Typography Features

Sanskrit Devanagari

Sanskrit terms are marked semantically clean with appropriate language attributes and translate="no" for screen readers and search engines:

The doctrine of 《धर्मः》 is central.
Or with double danda: 《धर्मः ||》

HTML output:

<span class="sanskrit-dev" translate="no" lang="sa">धर्मः</span>
<span class="sanskrit-dev" translate="no" lang="sa">धर्मः ॥</span>

Intra-Table Utilities (Line Breaks & Indentation)

In standard Markdown, line breaks inside table cells can be tricky. This plugin provides dedicated inline directives:

• :br renders a real <br> tag inside table cells.
• :indent renders indentation spacing.

| Term | Meaning |
| --- | --- |
| First term :br Second term | Meaning 1 :br Meaning 2 |

Highlighters

Predefined highlights:

• :sig[Text] -> <strong class="signalrot">Text</strong>
• :mark[Text] -> <mark class="marker-yellow">Text</mark>

Styling Built-in Elements

All default containers and inline elements documented above come with predefined CSS classes (e.g., .grammar-box, .note-box, .signalrot, .marker-yellow, .sanskrit-dev).

These classes are pre-styled for both light and dark mode in the bundled stylesheet markdown-it-extensible/css (theme/payer-theme.css). You can import them directly via import 'markdown-it-extensible/css' or override them in your custom stylesheet as desired.
