Now that's the core element used by impress.js.
That's the wrapper for your presentation steps. In this element all the impress.js magic happens.
It doesn't have to be a `<div>`. Only `id` is important here as that's how the script find it.
You probably won't need it now, but there are some configuration options that can be set on this element.
To change the duration of the transition between slides use `data-transition-duration="2000"` giving it
a number of ms. It defaults to 1000 (1s).
You can also control the perspective with `data-perspective="500"` giving it a number of pixels.
It defaults to 1000. You can set it to 0 if you don't want any 3D effects.
If you are willing to change this value make sure you understand how CSS perspective works:
https://developer.mozilla.org/en/CSS/perspective
But as I said, you won't need it for now, so don't worry - there are some simple but interesting things
right around the corner of this tag ;)

Again, we use a `data-` attribute, this time it's `data-scale="4"`, so it means that this
element will be 4 times larger than the others.
From presentation and transitions point of view it means, that it will have to be scaled
down (4 times) to make it back to its correct size.

And now it gets really exciting! We move into third dimension!
Along with `data-x` and `data-y`, you can define the position on third (Z) axis, with
`data-z`. In the example below we use `data-z="-3000"` meaning that element should be
positioned far away from us (by 3000px).
-->
<div id="tiny" class="step" data-x="2825" data-y="2325" data-z="-3000" data-rotate="300" data-scale="1">

This step here doesn't introduce anything new when it comes to data attributes, but you
should notice in the demo that some words of this text are being animated.
It's a very basic CSS transition that is applied to the elements when this step element is
reached.
At the very beginning of the presentation all step elements are given the class of `future`.
It means that they haven't been visited yet.
When the presentation moves to given step `future` is changed to `present` class name.
That's how animation on this step works - text moves when the step has `present` class.
Finally when the step is left the `present` class is removed from the element and `past`
class is added.
So basically every step element has one of three classes: `future`, `present` and `past`.
Only one current step has the `present` class.

Hint is not related to impress.js in any way.
But it can show you how to use impress.js features in creative way.
When the presentation step is shown (selected) its element gets the class of "active" and the body element
gets the class based on active step id `impress-on-ID` (where ID is the step's id)... It may not be
so clear because of all these "ids" in previous sentence, so for example when the first step (the one with
the id of `bored`) is active, body element gets a class of `impress-on-bored`.
This class is used by this hint below. Check CSS file to see how it's shown with delayed CSS animation when
the first step of presentation is visible for a couple of seconds.
...
And when it comes to this piece of JavaScript below ... kids, don't do this at home ;)
It's just a quick and dirty workaround to get different hint text for touch devices.
In a real world it should be at least placed in separate JS file ... and the touch content should be
probably just hidden somewhere in HTML - not hard-coded in the script.
Just sayin' ;)
-->
<div class="hint">
<p>Use a spacebar or arrow keys to navigate</p>
</div>
<script>
if ("ontouchstart" in document.documentElement) {
document.querySelector(".hint").innerHTML = "<p>Tap on the left or right to navigate</p>";
}
</script>
