Introduction

Readium CSS is a set of reference stylesheets for EPUB Reading Systems, starting with Readium 2.

Readium CSS provides styles for reflowable text:

• paged and scrolled views;
• a “patch” for HTML5 Suggested Rendering specific to publications (e.g. extra styles for hyphenation, breaks, etc.);
• default styles for unstyled ebooks;
• reading modes (day, night, and sepia);
• themes;
• user settings;
• media overlays and user highlights;
• a set of baselines and recommendations for accessibility, overrides, and internationalization.

Readium CSS is currently in alpha (version 1.0.0-beta.1).

Utilities

We’ve been using house-made web apps during ReadiumCSS that we made available in the project’s repo:

• Typeface Tester, to help pick fonts for reading apps or alternatives for EPUB files;
• Dynamic Leading Tester, to find the ideal line-height for a specified font.
