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 reported 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 an unnumbered heading from the contents

# Preface {.unnumbered}

# Colophon {.unnumbered .unlisted}

.unnumbered alone keeps the heading in the contents without a number; adding .unlisted takes it out. PDF ignores .unlisted without .unnumbered, so it alone draws a warning. DOCX and ODT list every heading either way. See Manuscript & structure for numbering across the whole book.
