Thanks for the article and making this gist. Using Sass mixins for utility classes in order to keep things leaner and simpler than say Tachyons or Tailwind is a great idea! Only thing I wondered, as I can't see any easy way to do this, would it be at all possible to also incorporate @media queries in this mixin for handy breakpoint changes to your utilities?
This is great, Sarah. Do you have any ideas for how to modify this to support passing multiple attributes to the mixin? For instance, I'm iterating through our spacing scale and creating .padding-x-<size> classes that would include both padding-left and padding-right attributes.
