Many websites today are designed with a mobile-first approach, but this can lead to issues when the pages are viewed on desktop devices. The content can appear overly large and stretched out, resulting in long pages that require more scrolling. This design trend, known as content dispersion, can have negative effects on usability, including increased cognitive load and interaction costs, difficulty understanding content, and user frustration. Content dispersion is a result of combining mobile-first design, minimalism, and large imagery. While content dispersion can have some positive effects, such as reducing information overload, it is important for designers to evaluate how their designs render on desktop and prioritize important content.
