Specifying a skin for a portal
Give your portal a look that is different from the rest of the application. By setting up a separate skin for a portal, you ensure that the portal does not share the design of the application, which gives you greater creative freedom.
You can associate each of your portals with a different skin, but a single skin for the
entire application is a best practice, because it helps you maintain a single,
consistent source of branding information.
Note: You cannot specify a skin for portals
that use the Cosmos design system or Cosmos React UI components.
