Updating the Cosmos theme in your application

Updated on December 13, 2022
Applicable to Theme Cosmos applications

Build your application by using the latest UI tools. By ensuring that the Theme Cosmos ruleset is up to date, you provide your application with a modern and responsive interface.

Theme Cosmos is the section-based version of the Cosmos design system, a low-code front-end system that provides a complete presentation layer with information architecture, interactions, and accessibility. Theme Cosmos represents a complete toolkit for UX development in case management applications.

After you update Pega Platform to the latest version, all new applications that use Theme Cosmos default to the most current version of the ruleset. Existing applications keep the previous ruleset version until you update it manually.

Caution: Updates to the Theme Cosmos ruleset might require development effort. For example, after an update, the styling or behavior of your application might change, which requires you to refactor and modify some of your custom CSS and sections to be in sync with the latest ruleset.

  1. In the header of Dev Studio, click the name of the application, and then click Definition.
  2. In the Built on applications section, click Add application.
  3. In the new row, enter Theme-Cosmos, and then select the latest version by pressing the Down arrow key.
  4. On the right side of the field with the previous version of Theme Cosmos, click the Delete icon.
  5. Click Save.
  • Skins

    Skins help you style the graphic elements of your interface, such as borders and backgrounds, separately from the content. This approach ensures greater consistency, promotes reuse, and provides you with tools to make quick changes to the graphic design of your application.

  • Managing Cosmos UI settings in case designer

    Adjust the Cosmos-based user interface of your application to the needs of your organization. By changing Cosmos settings, you can control case-level fields and case behavior to make the interface cleaner or more informative, according to your preferences.

  • CSS helper classes

    CSS helper classes are snippets of code that introduce minor formatting changes to your UI. If your application has many formats of the same type, and these formats vary only slightly, using CSS helper classes can save you development time by limiting the number of customized skin formats.

  • Uploading custom font files

    Ensure that your user interface meets the branding requirements of your company by adding new fonts to Pega Platform. Your custom font files can comprise standard fonts or icon fonts, which you can then add to the default icon set for your application.

  • Login screen customization

    You can customize the appearance of the login screen and other screens that unauthenticated users access, to maintain design consistency with your company's style guidelines.
