Silk UI is essentially a set of app templates and dozens of patterns, implemented in the form of OutSystems Blocks with configuration parameters and content placeholders. Silk UI patterns can be and dragged and dropped, and nested in OutSystems IDE. This allows developers to build full mobile and web screens, just by dragging the desired patterns.
Silk UI patterns cover the most used UI patterns and interactions in mobile and web apps, to distance developers as much a possible from the need to program CSS.
