The relationship to WCAG is explained for each requirement in its respective section.
It does not mean that the rest of the WCAG techniques are not applicable. As a result, although this section can be read without deep knowledge of WCAG conformance, to implement the accessibility requirements of this specification will require an understanding of [ WCAG 2.
Level AA conformance is often cited as the benchmark for accessibility in legal frameworks and policies, for example.
Additionally, any procurer or distributor of EPUB Publications can demand higher conformance requirements than the baseline defined here. Authors consequently need to ensure they understand the requirements their content has to meet to be considered accessible in any jurisdiction or distribution context, including seeking any necessary legal advice.
Minimum conformance with this specification does not supersede such requirements, and does not offer protection from any legal liability that might arise.
For example, it is not sufficient for individual Content Documents to have a logical reading order if the publication presents them in the wrong order. Likewise, including a title for every Content Document is complementary to providing a title for the publication: the overall accessibility is affected if either is missing.
The [ WCAG 2. Technically speaking, this is possible through a combination of two factors: a pre-ingestion manipulation of the text here is where a pool of experts, leaded by Mobidys, comes in with a specific html and CSS tagging profile. And a toolbar with buttons capable of interpreting and toggle styles and multimedia according to the specifications of that profile.
Specific reading apps have been developed to optimize User Experience. There are clearly special add-ons, so that entire classes and families can enjoy sharing the same book. I am aware that these solutions fail to scale.
First of all they require clinical experts in the content creation; secondly accessibility functions live in the content. Yet, now thousands of children have access to content like never before, in a form — an illustrated book in fixed-layout — wonderfully suitable for their needs. Do not use visual-only cues such as colored text, font size or positioning as the only clue to the meaning or importance of a word or section. Do not use tables or pictures of text to control the appearance of the content.
The meaning of the content should be the same both with and without any styles or formatting applied. Include a complete table of contents in the front matter and consider smaller tables of contents at the start of each section.
This is particularly important for academic, educational, and other complex texts. Create a structure by using numbered headings in a logical structure. For other tagged structures, specify their content with the epub: Specific tags are for specific content only i. Include semantic information to describe the content of a tag.
Any content embedded in an image is not available to visually impaired readers. If the textual contents of a table or image are required for comprehension of the document, use proper and complete markup for text and tabular data, including headers and scope attributes for tables. If images of text are unavoidable, provide a description and transcription of the text and use accessible SVG.
Accessible SVG graphics allow text in images to be rendered in an accessible way. They can also make it possible to deliver tactile images electronically to blind users with appropriate devices or to help automate the creation of tactile images that can be mailed to the reader with minimum human intervention. Every image should have a description, caption or alt text unless it is solely decorative.
Page numbers are the way many people navigate within a book. For any book with a print equivalent, use the epub: Include the ISBN of the source of the page numbers in the package metadata for the book.
To make sure each word will be rendered correctly, specify the default language of the content in the root html tag.
