ThemeBuilder

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 ASP.NET Core 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 ASP.NET Core app
