GITHUB: custom directive targeting a CSS property

I am on a task to trigger business rules at click on buttons sharing a CSS class in Angular, and I wanted to do a mini-POC on my own to check the suitability of such a solution.

So here it is: https://github.com/vinny59200/VVCUSTOMDIRECTIVE

A web page with a div containing text which ―takes a color, defined in the directive ―triggers a console log, specified in the directive. Have a good one!
