In the context of web application design, “responsive” implies that the application adjusts its layout and functionality based on the user’s device and screen size. A responsive design utilizes flexible grids, images, and CSS media queries to ensure optimal viewing experiences across desktops, tablets, and smartphones. This approach enhances usability by preventing the need for users to zoom or scroll excessively. The goal of a responsive web application is to provide a consistent and user-friendly experience, regardless of the device used to access it.
