Where should custom styles be applied in Pega for effective usage?

Applying custom styles through CSS class fields on layout and cell properties panels is the most effective method in Pega. This approach allows for a targeted and granular application of styles directly where they are needed in the user interface. By assigning CSS classes to specific layouts and cells, developers can create a more styled and responsive user interface without impacting other areas of the application. This practice enhances maintainability since style changes can be made at specific points without altering the entire skin or application configuration.

Utilizing CSS class fields ensures that the styles are modular and can easily be updated or overridden at the component level, providing flexibility in design. Moreover, it allows for the reuse of styles across different components, supporting consistency and adherence to design standards across the application.

In contrast, applying custom styles in the skin rule properties applies them globally, which may not be suitable for all elements, as local adjustments may be required. Setting styles directly in section rules or application configuration could lead to challenges in managing styles, as these methods may not provide the same level of specificity and could result in a cluttered design environment.
