If anyone’s interested, I’d be happy to organize a session introducing basic HTML and CSS. All you’d need to participate in this is a laptop with a good ol’ text editor and a browser. We can cover basic HTML markup and CSS syntax, and maybe end with some presentation/discussion of resources for going further.
If it turns out there isn’t enough time or space to do this, but folks are interested in it, we could always find time to talk in between sessions, or after the event.
