# Supported classes

Our Classic theme includes styling for a range of classes. You can apply these to elements in markdown.

## Formatting

Use these classes in your markdown to create specific formatting effects.

Feature Workflow class Block or inline Explanation Supports edition suffix
Bibliography list .bibliography Block Styles a list as a bibliography, for instance at the end of an academic book. No
Box .box Block Puts the element in a box, to set it off from the rest of the text. No
Chapter number .chapter-number Block Used for a chapter number before a chapter heading. (See the tip at Bold in the chapter on Markdown for another way to handle chapter numbers. No

First paragraph .first Block For any paragraph that starts a new set of paragraphs, flush left and with a gap above it. No
Float to top .float-top Block Floats the element to the top of its page. Useful for boxes. Applies to print output only. Yes

Page break: allow .allow-break Block Allows an element to break over a page where the default styles would normally prevent that. Apply the class to the parent element. No
Page numbering restart .page-1 Block Restarts page numbering from 1. Can be added to the first block element on a page, or to the YAML header, in addition to the main style, e.g. style: halftitle-page page-1 or style: chapter page-1. Recommended for any document that starts a book interior (e.g. title page), to retain correct pagination when creating a PDF ebook with a front cover No
Poetry .verse Block Designing poetry is tricky and important. Read about how to manage this in our workflow guide. No
Pull quote .pullquote Block Displays a paragraph as a pull quote. No
Sidenote .sidenote Block or inline A sidenote appears in a sidebar to the right of the text. No

Tracking: loosen .loosen-1 to .loosen-50 Block or inline Each increment loosens the space between letters by 0.001em (1/1000 of a em). Affects print output only. Yes
Valediction .valediction Block Used for the sign-off at the end of a letter, preface or foreword. No

## Reserved classes

You may also need to create your own classes for other uses. If you do, avoid using the same already-supported class names above. You should also avoid using the following ones, which are reserved for specific structural elements.

Class name Reserved for
index The home page of a collection, used for the style value in file YAML headers
cover A front cover, which will appear in ebook editions, used for the style value in file YAML headers
halftitle-page A book’s halftitle page, used for the style value in file YAML headers
previous-publications-page A book’s list of the author’s previous publications, used for the style value in file YAML headers
title-page A book’s title page, used for the style value in file YAML headers
copyright-page copyright or imprint page, used for the style value in file YAML headers
contents-page A book’s table of contents, used for the style value in file YAML headers
dedication-page A dedication page, used for the style value in file YAML headers
epigraph-page An epigraph page, used for the style value in file YAML headers
frontispiece-page A frontispiece page, used for the style value in file YAML headers
frontmatter For other prelim pages not accounted for otherwise, used for the style value in file YAML headers
chapter A book’s default chapter page (and the global default), used for the style value in file YAML headers

## The edition suffix

If you want to produce more than one print edition of a book from the same source file, you can’t use the same classes that affect text-flow – like .tighten-1, for instance – in both editions, because the text will flow differently in each edition.

Our workflow has a way to manage that. In the print CSS file, you can specify an edition suffix. For instance, if you’re producing a schools edition of a book, you might make your suffix -schools-edn. That suffix will be appended to the end of certain class names for that stylesheet. The default .tighten-1 class will become .tighten-1-schools-edn in your final print CSS.

(It’s a good idea to start a suffix with a hyphen and use all lowercase letters, to keep your output CSS neat. Never use spaces.)

Only some classes are affected – see the table above for which ones. The most important are the classes used for tightening and loosening letter-spacing, which are mostly used to control widows and orphans in print layout.

In your markdown, then, you’d use {:.tighten-1-schools-edn} instead of {:.tighten-1}, and that class will then only have an effect on your schools edition. If you had another edition, say a large-print edition with a -large-print suffix, you’d use a {:.tighten-1-large-print} tag in the markdown. These would match the classes automatically generated in each edition’s CSS.

Of course, one element can carry both classes. For instance, you might end up with a paragraph tagged with {:.tighten-1-schools-edn .tighten-1-large-print}. That paragraph would then be tightened in both print layouts.

## Deprecated classes

Early versions of the EBW used the following classes, which are no longer supported:

• shrink
• tighten, tight, x-tight, xx-tight, xxx-tight
• loosen, loose, x-loose
