Any way to inject styling into an AngularJS template in a contributed directive -

I am using a helpful tutorial that includes a template. I will use that template as ng-style directive In the template, I want to modify the use of a function to set styles on specific elements (i.e. set a background color based on a value within the conditionally stated direction).

Now, I can easily modify the ng-style instructions of the template which easily override the template in the template. However, given that the Directorate has its own separate area, I do not know which function I can say that I can define without modifying the definition of the definition.

Is there one way, the instructions that I can use in my override ng-style template, or b) whether my nG-style instructions have to be written in such a manner that they (or global) ) Can you use the $ radius?
