Page-level Configuration Reference

This page documents the [extra] front-matter keys Tapestry reads on individual pages (e.g. content/about.md, a blog post). These override their site-level equivalents where noted. For Zola's own standard front matter (title, description, date, updated, authors, draft, weight, slug, path, template, insert_anchor_links, [taxonomies], and so on), see Standard Zola front matter at the bottom of this page.

sidebar#

+++
title = "My Page"
# [extra]
# sidebar = "sidebar-snippet.md"   # custom content
# sidebar = false                  # force off
+++

The single-article template's columns 9–12 sidebar region is content-driven, not unconditionally reserved:

• Left unset, a sidebar renders automatically once the page has 2 or more headings, as an "on this page" table of contents.
• Set to a string, that path is loaded as a colocated Markdown snippet (relative to the page's own directory) and rendered into the sidebar instead of/alongside the auto TOC.
• Set to false, no sidebar renders regardless of heading count or a custom snippet, and the article reclaims the full 12 columns.

stylesheets#

+++
[extra]
stylesheets = ["css/one-off-page-style.css"]
+++

Additive with the site- and section-level stylesheets — see site-configuration.md. All three levels' stylesheets are linked together, not just the most specific one.

katex#

+++
[extra]
katex = true
+++

Overrides the site- and section-level katex setting for this page only — see site-configuration.md for the full precedence chain. An explicit true/false here always wins over whatever is set at the section or site level.

social_media_image#

+++
[extra.social_media_image]
path = "share-card.png"
alt_text = "A diagram of the proposed architecture."
+++

• path is a colocated image (relative to the page's own directory), automatically resized to 1200×675 and emitted as og:image / twitter:card meta tags.
• alt_text is optional but recommended; it becomes og:image:alt.
• If unset, the page falls back to the section-level social_media_image (see section-configuration.md), if any.

Quick reference#

Standard Zola front matter#

Keys like title, description, date, updated, authors, draft, weight, slug, path, template, insert_anchor_links, and [taxonomies] are standard Zola front matter, not Tapestry-specific — see Zola's own page content documentation for the full reference.
