Content is not designated solely by its form or its position on the screen.

The separation of content and form being the fundamental principle of accessibility, the designation of content by its form or its position prejudges the reader's ability to distinguish this form or find this location.

Objectives

  • Enable the understanding of information without access to visual support or when its rendering is altered.
  • Improve the accessibility of content to people with disabilities

Implementation

  • When content is designated in the physical version of the book by a reference to its form or its position, the information in the digital version of the same work must also be available by a textual mention including a hyperlink.

Control

  • This verification concerns a wide variety of potential cases, particularly in the flow of a text where reference is made to an illustration, a graph or a table. For each content concerned, it must be ensured that references to its form or position on the screen are not the only means of identifying it. We will then use an explicit reference to an identifier (example “See figure n°1”), a link to an anchor, etc.

Validation

  • Needs to be human verified.
