Which design practice emphasizes using similar designs for similar pages?

The practice that emphasizes using similar designs for similar pages is visual consistency. This design principle focuses on creating a coherent look and feel throughout an application or website, ensuring that users can quickly understand and navigate the interface. By applying uniformity in colors, typography, spacing, and layout across similar pages, users can leverage their previous experiences and familiarity with the interface, leading to a more intuitive user experience.

Visual consistency helps to establish a clear structure and hierarchy, giving users confidence that they know how to interact with various elements on different pages. This is especially important in applications where users frequently switch between different sections, as a consistent design aids in reducing cognitive load and improving usability.

In contrast, user-centric design focuses on tailoring the experience based on user needs and feedback, which may not always result in a uniform appearance across similar pages. The other practices, like adaptive layouts and responsive design, pertain more to how layouts adjust to different screen sizes and devices rather than ensuring visual similarities across similar pages.
