Expected behavior

Being able to write something like .button{ @extends btn; ... }

Actual behavior Getting build errors regarding dependencies for the ng-uikit-pro ng module.

I want to build off of your libraries but there are undefined varibales that are causing compilation errors.

I have import statements at the top of my styles.css file that cover all of the base sass files as well as the material libaries.

Is it possible to extend your scss files?
