] | [Twine](https://twinery.org/) is an open-source tool for telling interactive, nonlinear stories.
It generates a single html with multiples pages.
Maybe it is not the right tool for you but it could be useful for someone else looking for something similar. | It is, in theory, possible using `data:` scheme URIs and frames, but that is rather a long way from practical.
You can fake it by hiding some content with JS and then revealing it when something is clicked (in the style of [tabtastic](http://phrogz.net/js/tabtastic/index.html)). |
