(This is going to be a short post today. Between getting home very late from work and then hanging out with a friend of mine I rarely see, I don’t have much time left to get this out before the day ends.)
I’ve been slowly learning the extra syntax that Twine supports from its underlining engine of TiddyWiki. Like, for example, enclosing some text with “//” will give it an Italics emphasis. Using “==” will mark it with a strike-through style.
However, unlike my learn-it-when-I-need-it approach, Leon Arnott has done a fantastic job of demonstrating nearly all possible variations of valid syntax on this page. There’s even some examples of combining in-line CSS with Twine’s own “<html>” tag to give authors an approach that doesn’t use separate stylesheet passages. I highly recommend checking out the examples as a way to further learn what Twine is capable of doing.
