<h2>Hello There</h2>
<p>
reveal.js enables you to create beautiful interactive slide decks using HTML. This presentation will show you examples of what it can do.

<h2>Vertical Slides</h2>
<p>Slides can be nested inside of each other.</p>
<p>Use the <em>Space</em> key to navigate through all slides.</p>

These guys come in two forms, inline: <q cite="http://searchservervirtualization.techtarget.com/definition/Our-Favorite-Technology-Quotations">The nice thing about standards is that there are so many to choose from</q> and block:
</p>
<blockquote cite="http://searchservervirtualization.techtarget.com/definition/Our-Favorite-Technology-Quotations">
&ldquo;For years there has been a theory that millions of monkeys typing at random on millions of typewriters would
reproduce the entire works of Shakespeare. The Internet has proven this theory to be untrue.&rdquo;

<h2>Intergalactic Interconnections</h2>
<p>
You can link between slides internally,
<a href="#/2/3">like this</a>.
</p>
</section>
<section>
<h2>Speaker View</h2>
<p>There's a <a href="https://revealjs.com/speaker-view/">speaker view</a>. It includes a timer, preview of the upcoming slide as well as your speaker notes.</p>
<p>Press the <em>S</em> key to try it out.</p>
<aside class="notes">
Oh hey, these are some notes. They'll be hidden in your presentation, but you can see them if you open the speaker notes window (hit 's' on your keyboard).
</aside>
</section>
<section>
<h2>Export to PDF</h2>
<p>Presentations can be <a href="https://revealjs.com/pdf-export/">exported to PDF</a>, here's an example:</p>
<iframe data-src="https://www.slideshare.net/slideshow/embed_code/42840540" width="445" height="355" frameborder="0" marginwidth="0" marginheight="0" scrolling="no" style="border:3px solid #666; margin-bottom:5px; max-width: 100%;" allowfullscreen> </iframe>
</section>
<section>
<h2>Global State</h2>
<p>
Set <code>data-state="something"</code> on a slide and <code>"something"</code>
will be added as a class to the document element when the slide is open. This lets you
apply broader style changes, like switching the page background.
</p>
</section>
<section data-state="customevent">
<h2>State Events</h2>
<p>
Additionally custom events can be triggered on a per slide basis by binding to the <code>data-state</code> name.
</p>
<pre><code class="javascript" data-trim contenteditable style="font-size: 18px;">
Reveal.on( 'customevent', function() {
console.log( '"customevent" has fired' );
} );
</code></pre>
</section>
<section>
<h2>Take a Moment</h2>
<p>
Press B or . on your keyboard to pause the presentation. This is helpful when you're on stage and want to take distracting slides off the screen.
