When you upgrade to a newer version of Pega Platform, you can update the UI Kit layer version or keep your previous version. However, if you do not update UI Kit to the latest available version, certain out-of-the-box functionalities might not work as intended.

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 UIKit, and then select the latest version by pressing the Down arrow key.

4. Next to the previous version of UI Kit, 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.

• Updating the Cosmos theme in your application

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

• 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.
