Hello Telerik-Team,

Since we design now our themes for the application through the Themebuilder we found some missing features that regards the usage of native css functions.

It is very simple to set up the theme with the default components, but yesterday we started with custom components. Soon we found it that no css functions where supported at your end.

For calculating the right amount of rem and  repeat grid colums it would be great to have it in one place, instead of manipulating CSS code after we've already exported the theme and implemented it into our application.

Hello Telerik Team,

We are currently using ThemeBuilder to design our application themes. While the tool is incredibly straightforward for styling default components, we encountered a limitation when working with custom components: native CSS functions currently do not appear to be supported.

Specifically, we need the ability to use functions like calc() (for calculating accurate values) and repeat()(for CSS grid columns) directly within the ThemeBuilder interface.

Because these functions are not supported, we currently have to manually manipulate the CSS code after exporting the theme and integrating it into our application. Adding support for native CSS functions would allow us to keep all styling centralized in one place and eliminate these manual post-export workarounds.

Could you let us know if supporting native CSS functions is something that could be added to your roadmap?

Thank you,

Anthony Timmel
