Making applications responsive
You should create responsive applications.
A responsive page enables you to present content so that the presentation adjusts to the size of the browser window. Intrexx can be used to design your portal and all its application pages for the three display sizes SMALL (e.g. smartphones), MEDIUM (e.g. tablets) and LARGE (e.g. desktop PCs).
