Service Studio 5.1 Help
You can apply styles to all widgets in your web screens, emails, and web blocks. For that, edit the Web Style Sheet and define the styles that are to be applied.
The style sheet can be:
Internal: The style sheet that you use at development time and runtime is the same. The style sheet is internal in the sense that you cannot change the location and the file name; it is managed internally by Agile Platform. You can only change the styles of the style sheet. The use of an internal style sheet is the default option available in Service Studio.
Learn more about the Internal Style Sheet.
External: The style sheet is loaded only at runtime and you cannot use it while designing your Mobile Web screens; at development-time, the style sheet that is used is the internal one.
