Advanced Features

These optional features activate automatically when specific patterns are detected in your content.

Drop Cap Images (WordPress)

Add decorative initial images (medieval manuscript style) to your WordPress posts. The image floats left as a visual drop cap while the first letter remains in the HTML for SEO.

Usage: Name your image file with enluminure in the path:

![[Assets/enluminure-A.png]]

Your article content starts here...

Or specify in frontmatter:

---
enluminure: Assets/drop-caps/letter-A.png
---

The image will be:

• Uploaded to WordPress
• Positioned as a floating drop cap (200px max-width)
• Set as the featured image and Open Graph image (Rank Math)
• Removed from inline content to avoid duplication

Note: This feature only activates when "enluminure" appears in an image path. Regular images are unaffected.

Bilingual Publishing (WordPress + Polylang)

Publish French and English versions of your content simultaneously using the Polylang plugin.

1. Enable in Settings:

• Go to WordPress server settings
• Enable "Polylang" in the Multilingual section
• Configure category mappings for each language

2. Write bilingual content using callouts:

> [!info]- 🇫🇷 Titre français
> Votre contenu en français ici.
>
> Plusieurs paragraphes sont supportés.

> [!info]- 🇬🇧 English Title
> Your English content here.
>
> Multiple paragraphs are supported.

3. Publish: The plugin will create two linked WordPress posts (one FR, one EN) with proper Polylang language tags.

Note: This feature only activates when both 🇫🇷 and 🇬🇧 callouts are present and Polylang is enabled.
