Hi. having just seen the excellent tutorial by @matjaz on modifying sass variables in sass files and _over riding_ (if that is the correct terminology) the default Bootstrap classes. …what is/was the usual best practice way? with vanilla framework css classes? not just or as well as sass variables? ![2018-03-06_10-25-04](https://canada1.discourse-cdn.com/flex036/uploads/pinegrow/original/2X/b/b7e19deb04afe45c594ad04c6e7ba160889f7b4a.png) I was doing 1. (funny, I thought there was a _copy too_ option too… was there in an earlier version) but, do we now use 2. instead? ---

The question is never: “What is the better/best way!” The question is: “What do I want to achieve” and then decide which way going down the road. The first is prime to overwrite an existing value, the latter for extending the existing class by a new value. Cheers Thomas
