Does Valo include the "fa-stack" CSS selector?

I’m trying to use the FontAwesome CSS styles but they do not seem to be rendering.

Hey Paolo, could you elaborate a bit? Are you referring to the styles that are part of FontAwesome’s official download?

Then no, I don’t think we support that out of the box. Don’t think there’s any reason why you couldn’t include those styles/files in your own project, though.
