Stack is a presentation library
with simple, scroll-based navigation.
Scroll down to continue.
In addition to the mouse,
you can scroll with the keyboard:
use the arrow keys,
the space bar,
or page up and page down.
Multiple key presses will skip multiple slides.
You can even grab the scroll bar!
← When this bar reaches the top,
the next slide will fade in.
If you resize the window,
slide content will scale up or down
to fit automatically.
Use activate and deactivate events
to enable complex animations
only when visible.
