In WorkWithPlus for Web 15 you will be able to allow end-users to change at runtime the following customizations:
- Font size
- Background style (dark or light)
To have this functionality available, you have to enable it by running the Design System Wizard (WorkWithPlus > for Web > Design System Wizard).
If you have already run Design System Wizard, you should select 'Current Design System', then in step 2 you will see Change color, Change background style, and Change font size options. Then in step 10, by clicking on the 'IMPORT DESIGN SYSTEM' button, a window will appear where you can select 'Import only needed objects' and only the objects necessary to have the new functionality will be imported.
