Native styles

Most styling comes from shortcuts. A small set of native classes need no shortcut — Pandoc understands them directly, and Keystone honors them without one. This page is the complete list; any other class is rejected at build time.

Text

Wrap a run of text in a bracketed span carrying the class:

Class	Renders as	Example
.smallcaps	small caps	[Roman Senate]{.smallcaps}
.underline (alias .ul)	underline	[important]{.underline}
.mark	highlight	[note this]{.mark}

Small caps for [names and epigraphs]{.smallcaps}.

An [underlined phrase]{.underline}, or its [.ul alias]{.ul}.

A [highlighted phrase]{.mark} mid-sentence.

All three render in PDF and EPUB (and in DOCX/ODT where the word processor supports the effect). They each do one specific thing — for a different face, size, or weight, use the font shortcut instead.

Headings

Two native classes apply to a heading rather than inline text:

Class	Effect
.unnumbered	drop the heading from the numbering sequence
.unlisted	drop the heading from the table of contents

# Preface {.unnumbered}

# Colophon {.unlisted}

The two differ: .unnumbered stays in the contents but loses its number; .unlisted keeps its number but drops from the contents. See Manuscript & structure for numbering across the whole book.
