I read the documentation, and there is a flag for enabling gradients on certain components: So maybe I am just stupid, but I don't see how this flag ($enable-gradients: true;) is supposed to do anything at all, I can find only a single reference to it in Bootstraps SASS files (.scss).
So how do i get some nice looking gradients in Bootstrap 4 without having to change all the classes like .btn-info? The presence of this flag seems to indicate that there is an elegant solution - if so I am just unable to find it..
Or maybe this variable was just created "in preparation" for themes, so they can build on top of it?
