Maintaining consistency between a link’s appearance and its function helps users understand and navigate the ebook’s internal interface more easily.

Objectives

• Improve the identification of links and their respective functions.

Implementation

• Apply consistent styling—including color, font weight, case, and underlining—to groups of links that serve the same function.

Control

• Check that links with the same function (such as inline links, footnote references, or social media links) have a consistent visual presentation throughout the ebook.
