ThemeBuilder Overview

Updated on Dec 10, 2025

The ThemeBuilder is an online tool that enables you to create custom themes and instantly preview how the components will look. The tool generates a CSS file that you can use in your Kendo UI app instead of a built-in theme.

Visit the ThemeBuilder documentation to learn how to:

• Create a custom theme
• Migrate custom themes to new component versions automatically or manually
• Export and use a theme in your Kendo UI app
