Suppose you want your Twine game to have that classic feel to it. You want pages to snap into place instantly, without even a moment of fade-in. All business. 90s web style. So sudden that it's like the game can read your thoughts.
Well, here's some CSS code that suppresses the default fade-in transition between passages:
.passage { opacity:1 !important; }
All this code does is remove functionality, which is why it's pretty simple. It will also work with Jonah as well as Sugarcane.
