This specification, EPUB Content Documents 3.0, defines profiles of HTML5, SVG, and CSS for use in the context of EPUB® Publications. This specification is one of a family of related specifications that compose EPUB 3, the third major revision of an interchange and delivery format for digital publications based on XML and Web Standards. It is meant to be read and understood in concert with the other specifications that make up EPUB 3: The EPUB 3 Overview [EPUB3Overview], which provides an informative overview of EPUB and a roadmap to the rest of the EPUB 3 documents. The Overview should be read first. EPUB Publications 3.0 [Publications30], which defines publication-level semantics and overarching conformance requirements for EPUB Publications. EPUB Open Container Format (OCF) 3.0 [OCF3], which defines a file format and processing model for encapsulating a set of related resources into a single-file (ZIP) EPUB Container. EPUB Media Overlays 3.0 [MediaOverlays30], which defines a format and a processing model for synchronization of text and audio. This specification supersedes Open Publication Structure (OPS) 2.0.1 [OPS2]. Refer to [EPUB3Changes] for information on differences between this specification and its predecessor.
Abstract
Overview
ISO/IEC TS 30135-3:2014 - EPUB Content Documents 3.0 - defines the profile of HTML5, SVG and CSS to be used inside EPUB 3 digital publications. Issued as part of the ISO/IEC TS 30135 series, this technical specification is one component of the EPUB 3 family and is intended to be read alongside sibling documents such as the EPUB 3 Overview, EPUB Publications 3.0, EPUB Open Container Format (OCF) 3.0 and EPUB Media Overlays 3.0. The spec replaces the earlier OPS 2.0.1 definition and establishes content- and reading-system-level conformance rules for XHTML content documents, navigation documents, SVG content, stylesheet profiles and scripted content in EPUB publications.
Key topics and requirements
- Content profiles: Defines an XHTML Content Document profile based on HTML5 (XHTML syntax) and a restricted subset of SVG 1.1 for inline and standalone vector graphics.
- CSS profile: Uses CSS 2.1 as a baseline and incorporates selected CSS3 modules and EPUB-specific CSS constructs (fonts, writing modes, media queries, multi-column, ruby, speech-related properties).
- Conformance rules: Specifies document and file properties (XML conformance, schema validity, recommended .xhtml extension) and enumerates where HTML5 behavior is inherited or constrained.
- Reading system behavior: Defines required processing semantics for EPUB Reading Systems, including a simplified processing model that does not mandate support for scripting, HTML5 forms or the full HTML5 DOM. Reading systems must honor EPUB-specific deviations and constraints.
- EPUB extensions: Adds EPUB-specific HTML5 extensions such as semantic inflection (the epub:type attribute), content switching elements (epub:switch, epub:case, epub:default), epub:trigger, and navigation document constraints (nav element types like toc, page-list, landmarks).
- Accessibility & media: Covers Text-to-Speech (TTS) and interaction with ARIA where applicable; defines scripted content and the optional JavaScript epubReadingSystem object (e.g., hasFeature).
Applications and who uses it
- Publishers and content authors: to create EPUB 3 publications that are portable, accessible and conformant across reading systems.
- Reading-system developers: to implement correct processing, layout and feature support for EPUB content documents, navigation, SVG, CSS profiles and media overlays.
- Tooling and conversion vendors: to validate, generate and optimize EPUB 3 packages (OCF containers) and to ensure compliance with EPUB Content Documents requirements.
- Accessibility specialists: to implement semantic markup, TTS support and ARIA integration for accessible e‑books.
Related standards
- EPUB 3 Overview, EPUB Publications 3.0, EPUB Open Container Format (OCF) 3.0, EPUB Media Overlays 3.0 (sibling ISO/IEC TS 30135 parts).
- Underlying web standards referenced: HTML5, SVG 1.1, CSS 2.1 / CSS3 modules.
Keywords: ISO/IEC TS 30135-3:2014, EPUB3, EPUB Content Documents 3.0, HTML5, SVG, CSS profile, EPUB navigation, reading system conformance, epub:type, accessibility.
