A responsive web app is a type of web application that is designed to automatically adjust its layout and design in order to provide an optimal viewing and interaction experience on any device, regardless of its screen size or resolution. This means that a responsive web app will look and function well on both desktop computers and mobile devices such as smartphones and tablets. The goal of a responsive web app is to make the user experience as seamless and consistent as possible, no matter what device the user is using to access the app.


Although VisualNEO Web uses absolute positioning, it's possible to create real responsive Apps by using the included BootStrap CSS classes.
It's also possible to rescale your application to fill the screen by using FitAppToScreen command.


From version 21.12.26 a Flexbox based grid system is available too.
