When you publish your story to an HTML file, you can choose between story formats. These story formats control both the basic appearance and behavior of your story, though you can customize both of these via individual changes you make to your story.

There are two main story formats to choose from:

• Jonah
  This displays your story with black text on a white background, and as a reader clicks links in your story, the text expands. A reader can review earlier passages of your story by scrolling upwards. This approach is called stretchtext.
• Sugarcane
  This displays your story with white text on a black background. Readers can only see one passage at a time, though they can use their browsers' back buttons to return to a previous passage, or use a special Rewind menu to jump back to particularly significant passages.

You can switch story formats at any time.

Both Twine and twee allow you to publish to TiddlyWiki format. This is included for backwards compatibility — both Jonah and Sugarcane are based on the TiddlyWiki codebase — but don't make for particularly compelling story experiences.
