Le libellé de chaque lien décrit sa fonction ou la nature du contenu vers lequel il pointe
A link must specify its target, such as another paragraph within the ebook, a URL, an external resource or a JavaScript animation.
Objectives
Allow to accurately identify the nature of the link and avoid wrong actions.
Allow screen readers to specify explicit target
Improve accessibility of content to readers with disabilities.
Implementation
Unambiguously indicate the content of the target page of the link, the link function or its behavior, case in the link label (portion of text located between the and tags or in the textual alternative of the image placed between these tags, possibly combined with text libellet).
Control
In the source code of each text link or image link:
Verify that the link label explicitly designates the nature or function of the target content, or the specific function of the link.
Check, in the case of image links, that the image’s alt attribute performs this role.
