Underlining is reserved for links.

Browsing the web has ingrained the habit of associating underlined content with links. By highlighting content that is not a link, there is a risk of causing unnecessary clicks. Please note, this rule does not require you to underline your links.

Objectives

• Avoid unnecessary clicks on underlined content perceived as hyperlinks.
• Make it easier to identify links.

Implementation

• Do not use underlining for simple text or elements that are not links.

Control

• In each file containing underlined content:
  • Identify underlined texts in the ebook;
  • Check the nature of this content to verify whether they are indeed hyperlinks.

Validation

• Needs to be human verified.
