## Introduction

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

Readium CSS provides: 

- a CSS normalize for EPUB contents;
- paged and scrolled views;
- default styles;
- reading modes (night, sepia, etc.);
- themes;
- user settings;
- media overlays and user highlights.

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

## Download

[You can alternatively download this documentation as an EPUB file](https://github.com/readium/readium-css/raw/master/docs/ReadiumCSS_docs.epub).

## Utilities

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

- [Typeface Tester](utils/Typeface-tester.html), to help pick fonts for reading apps or alternatives for EPUB files;
- [Dynamic Leading Tester](utils/DynamicLeading-tester.html), to find the ideal line-height for a specified font.
