DESIGN METHODS FOR RESPONSIVE COMMERCIAL WEBSITE INTERFACES BASED ON MOBILE INTERACTION PATTERNS

In the current digital landscape, the success of mobile commerce is tied directly to the quality of the user interface. This study examines how shifting to a "Mobile First" philosophy fundamentally reshapes the architecture of web applications. We look beyond mere technical specifications to explore the physics of user-screen interaction—from the ergonomics of "active finger" movements to reducing page weight by stripping away bulky third-party frameworks. Our research demonstrates that leveraging native HTML5/CSS3 code alongside flexible layouts (Grid and Flexbox) creates interfaces that are not only lightning-fast but also intuitively adaptive to human behavior.
