Design and Customize with Meridian Styling Tools

Progress ThemeBuilder by Telerik is a comprehensive visual design tool that accelerates user interface customization for Telerik and Kendo UI web components. ThemeBuilder enables you to style virtually every appearance-related property of the UI components, from top-level elements to the smallest of details, without requiring direct CSS manipulation. It integrates with existing development processes and allows developers to create, modify, and maintain consistent and visually appealing themes across applications. This tool significantly reduces the time and effort required for UI customization and makes it easy to align them with branding and design specifications.

The Progress ThemeBuilder 2026 Q2 update introduces support for the new Meridian theme, giving developers greater flexibility to design and customize modern user interfaces through an integrated theming workflow. With access to updated styles, components, and design tokens directly within ThemeBuilder, teams can more easily create polished and consistent application experiences that align with the latest Kendo UI design system. The update also streamlines theme management and customization, helping developers accelerate UI development while maintaining visual consistency and brand alignment across projects.
