deck.split.js is a deckjs extension that helps you split long slide into
multiple small slides.
Just drop the whole repo into deck.js's extensions directory, then include
the script in your slide.
To split a long slide, you need to indicate position inside original slide by adding following line:
<div style="page-break-after:always"></div>Indeed, it could be any tag set with page-break-after:always style. Every
time you add this line, a new slide with the same title will be created, so you
can split your slide into pieces as much as you want.
