I tried to start with impress.js to create some HTML/CSS3 presentations.
Unfortunately I cannot get even the simplest example working.
<html lang="en">
<head>
<title>Impress Demo</title>
</head>
<body>
<div id="impress">
<div id="start">
<p style='width:1000px;font-size:80px;text-align:center'>Creating Stunning Visualizations</p>
<p>Impress.js</p>
</div>
<div id="slide2" data-x="-1200" data-y="0">
<p style='width:1000px;font-size:80px;'>First Slide Moves From Left To Right</p>
<p>Impress.js</p>
</div>
</div>
<script type="text/javascript" src="../js/impress.js"></script>
<script type="text/javascript">impress().init();</script>
</body>
Howver, in Firefox (tested also in Chrome) I get the following error in dev console:
Empty string passed to getElementById() @ impress.js:90
Any ideas?
Every div that you want to be a step in div#impress
should have a class="step"
added to it.
This code should work
<div id="impress">
<div class="step" id="start">
<p style='width:1000px;font-size:80px;text-align:center'>Creating Stunning Visualizations</p>
<p>Impress.js</p>
</div>
<div class="step" id="slide2" data-x="-1200" data-y="0">
<p style='width:1000px;font-size:80px;'>First Slide Moves From Left To Right</p>
<p>Impress.js</p>
</div>
</div>
