Design systems help you introduce consistency to the applications that you build. By choosing to use a design system, you can scale your designs to maintain a unified presence across a number of platforms with less effort.

A design system is a library of patterns and rules that determine how an interface responds to user interaction. Design systems contain the best practice guidelines, operational assets, and UI components that are required to deliver the interface. For example, a design system might include a reusable table component that supports sorting, filtering, and grouping. You can source every table in your application from that component, which means that every table in the application can have the same basic architecture and rely on consistent rules to model user interactions.

Some organizations develop proprietary design systems to unify the presentation, behavior, and structural rules of their application interfaces. However, most businesses rely on the design system that is provided by Pega. Either approach helps improve consistency, and creates a system that is easier to upgrade and maintain.

• 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 UI Kit in your application

  Ensure that your application includes a modern, responsive, and consistent UI by updating the out-of-the-box UI Kit layer in your application stack.

• 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.
