I am NOT a programmer and I don't know a lot of HTML. Yet I am playing around with pieces of code to try to customize the TiddlyWiki I am using for my novel. Today, I've achieved one tweak. I've added a plugin that allows the reader to adjust the font size. I didn't create it, of course. I'm a codes scavenger.
I spent most of the afternoon trying to figure out how to automatically indent the first line of every paragraph. I still can't figure it out.
