The label of each link describes its function or the nature of the content to which it points.

The label of a link must specify its target, whether for example another paragraph within the ebook, a URL, an external resource or even a JavaScript animation.

Objectives

• Allow the nature of the link to be precisely identified and avoid erroneous actions.
• Allow screen readers to indicate the target explicitly
• Improve the accessibility of content to people with disabilities.

Implementation

• Indicate unambiguously the content of the target page of the link, the function of the link or its behavior, if applicable, in the wording of the links (portion of text located between the tags and or in the textual alternative of the image placed between these tags, possibly combined with the textual wording).

Control

• In the source code of each text link or image-link
  • Check that the wording of the link explicitly designates the nature or function of the targeted content, or even the specific function of the link;
  • Check, in the case of image links, that the alt attribute of the image plays this role.

Validation

• Needs to be human verified.
